Buying Off-Plan – VEFA

Understanding VEFA in Luxembourg

VEFA, or Vente en l’État Futur d’Achèvement, is the French term used for the purchase of a property before it is fully completed. It is commonly called “buying off-plan”.

In Luxembourg, this type of purchase is regulated by law and defines the rights and obligations of both the developer and the buyer.

With a VEFA, the buyer becomes the owner of the land and of the building as construction progresses. The price is paid gradually, according to the progress of the works, while the developer remains responsible for the construction until the property is completed and handed over.


How does buying off-plan work?

1. Choose your future home

You choose your home based on the plans, project description, specifications and included features.

Depending on the stage of the project, you may also have the possibility to choose certain finishes or make some personal adjustments.

2. Sign the notarial deed

The purchase of a property under construction is completed through a notarial deed.

The deed sets out the main details of the purchase, including:

  • the description of the property;
  • the purchase price;
  • the payment schedule;
  • the expected delivery date;
  • the conditions of the sale;
  • and the applicable guarantees.

It also states whether the price can be revised and, if so, under which conditions.

3. Pay according to the progress of the works

One of the main principles of a VEFA is that the construction price is paid progressively, as the work progresses.

The law sets rules for these payments, and the exact payment schedule is included in the notarial deed.

This means that you do not have to pay the full construction price at once.

4. Construction of your future home

Once construction begins, the developer carries out the project according to the contractual documents.

You can follow the progress of the construction and see your future home gradually take shape.

5. Handover and reception of your home

Once the works are completed, the property is handed over to the buyer.

A reception inspection is carried out to check the condition of the property and, where necessary, record any defects or outstanding items.


A guarantee to protect the completion of the project

Luxembourg law provides, for the relevant sales of properties under construction, a completion guarantee or, under the conditions provided by law, a refund guarantee.

Completion guarantee

A financial institution can provide a completion guarantee. Under the terms of the guarantee and the applicable law, it is intended to ensure that the funds needed to complete the building are available if the developer is unable to fulfil its obligation to complete the project.

Refund guarantee

Under the conditions provided by law, the completion guarantee can be replaced by a guarantee allowing the buyer to recover the payments already made if the sale is cancelled because the property cannot be completed.


What happens after delivery?

The reception of the property is an important step in the purchase.

It allows the buyer and the developer to check the condition of the property and, where necessary, record any defects or outstanding items.

Luxembourg law also provides for specific legal responsibilities and guarantees for construction defects, depending on the type and nature of the works concerned.


What if the property is part of a residence?

If your property is part of a building or residence with several owners, the purchase also includes documents relating to the co-ownership of the building.

These documents define, among other things:

  • the private areas;
  • the common areas;
  • the shares of each owner;
  • and the rules governing the co-ownership.

The co-ownership regulations also set out the rules for the use and management of the common areas.


Why buy off-plan?

A brand-new home

You are buying a new property designed and built according to the requirements applicable to the project.

A home designed for today

The property is designed with current expectations for comfort, insulation, energy performance and modern equipment in mind.

Progressive payments

The construction price is paid gradually, according to the progress of the works and the terms of the sales contract.

A clear contractual framework

VEFA is regulated by Luxembourg law, with specific rules concerning the contract, payments and guarantees.

The opportunity to personalise your home

Depending on the stage of construction, you may have the opportunity to choose certain finishes or options and make your future home more personal.


Before signing: what should you check?

Before committing to your purchase, we recommend carefully reviewing:

  • the sales contract;
  • the plans;
  • the specifications;
  • the description of the finishes and equipment;
  • the purchase price and payment schedule;
  • the delivery date;
  • any price revision conditions;
  • the guarantees provided for in the contract.

Your notary and your financial institution can also help you review the contract and prepare your financing.

Financing Your Property Purchase

Plan your financing with confidence

Buying a property is an important financial commitment. Before making a decision, it is essential to prepare a clear and realistic financing plan.

Your budget should take into account the purchase price, acquisition costs, your personal contribution, your mortgage and any financial assistance you may be entitled to.

A well-prepared financing plan helps you understand your budget and your monthly payments, and allows you to approach your property purchase with greater peace of mind.


What costs should you plan for?

The purchase price is the main cost, but it does not always represent the total cost of your project.

Your budget may also include:

  • registration and other acquisition costs;
  • notary fees;
  • mortgage and financing costs;
  • outstanding balance insurance;
  • possible bank fees;
  • options or upgrades not included in the purchase price;
  • certain connection or landscaping costs, depending on the project.

For a new property, the included features and services are described in the contractual documents and specifications.


The purchase price and VAT

Under certain conditions, Luxembourg applies a reduced VAT rate of 3% to the creation or renovation of a home intended as a main residence.

This can be particularly relevant when buying a new property or a property under construction.

The conditions for applying the 3% VAT rate depend on the buyer’s situation and the type of property.


Your personal contribution

Your personal contribution is the amount of money you invest directly into your property project.

It may come from your savings and, depending on your situation, from certain financial assistance schemes.

The amount required depends on several factors, including:

  • the purchase price;
  • acquisition costs;
  • the amount the bank is willing to finance;
  • your income;
  • your existing financial commitments;
  • your family situation;
  • your repayment capacity.

There is therefore no single required level of personal contribution for every buyer.


The mortgage loan

A mortgage loan is usually the main source of financing for a property purchase.

Before approving a loan, the bank will assess your financial situation and your ability to make the repayments.

The amount you can borrow, the duration of the loan, the guarantees required and the other conditions depend on your personal situation and the property project.

We recommend comparing different offers and looking at the overall cost of the loan, rather than only the advertised interest rate.


Fixed or variable interest rate?

Choosing the right interest rate is an important part of your financing plan.

Fixed interest rate

The interest rate remains fixed for the period specified in the loan agreement.

This provides greater visibility over your monthly payments and the cost of the loan during that period.

The conditions for early repayment or changing the loan may vary depending on the agreement with your bank.

Variable interest rate

The interest rate may change during the loan period according to the conditions set out in the agreement.

A variable rate may allow you to benefit from lower interest rates if market conditions become more favourable. However, it also means that the cost of your loan may increase if interest rates rise.

A combination of both

Some banks offer financing solutions combining fixed and variable interest rate periods.

The right solution depends on your financial situation, your plans and your ability to accept possible changes in interest rates.

There is no single solution that is right for every buyer.


Government assistance

Depending on your income, family situation and the characteristics of your property, you may be eligible for various housing assistance schemes in Luxembourg.

These may include:

  • the home ownership subsidy;
  • the savings subsidy;
  • the interest subsidy;
  • the State guarantee;
  • certain energy-related subsidies.

The eligibility conditions and amounts depend on each scheme and may change over time.

We recommend checking the assistance available to you when preparing your financing plan.


Build your financing plan

A financing plan compares the total cost of your project with the funds available to finance it.

TOTAL PROJECT COST

Purchase price

  • Acquisition costs
  • Financing costs
  • Possible options and improvements

SOURCES OF FINANCING

Personal contribution

  • Mortgage loan
  • Possible government assistance

The aim is to make sure that your available resources cover the full cost of the project while keeping your monthly repayments at a level that suits your financial situation.


Before making a commitment

Before signing your purchase, we recommend asking your bank or financial advisor for a personalised financing simulation.

This will help you assess:

  • your borrowing capacity;
  • the amount of personal contribution required;
  • your monthly repayments;
  • the loan duration;
  • the overall cost of the financing;
  • the guarantees required;
  • and any government assistance you may be entitled to.

Good financing preparation is the first step towards a successful property purchase.

Property Taxation in Luxembourg

Key tax benefits to know before buying a property

Buying a property in Luxembourg involves various taxes and fees. However, when a property is intended to be your main and personal residence, certain tax benefits may significantly reduce the cost of your purchase.

The two main schemes to know are the “Bëllegen Akt”, which reduces registration and transcription duties, and the 3% VAT rate, which may apply to certain new construction or renovation projects.

These are two separate tax schemes, each with its own conditions.


Registration and transcription duties

When buying a property in Luxembourg, the standard registration and transcription duties are 7% of the purchase price:

  • 6% registration duty
  • 1% transcription duty

These duties are generally paid when the notarial deed is signed.

For buyers purchasing a property as their main and personal residence, the Bëllegen Akt may reduce these costs, subject to the applicable conditions.


The Bëllegen Akt

A tax credit for your main residence

The Bëllegen Akt is a tax credit on registration and transcription duties. It is available, under certain conditions, to individuals buying a property for their personal residence.

The tax credit is currently limited to:

€40,000 per buyer

When several buyers purchase a property together and each meets the eligibility requirements, each buyer may benefit from their own tax credit.

A minimum amount of €100 in registration and transcription duties remains payable in all cases.


Which properties can qualify?

The Bëllegen Akt may apply to:

  • a house;
  • an apartment;
  • a building plot intended for your main residence;
  • a property under construction;
  • certain related outbuildings, such as a garage or garden.

The property must be intended to become your main, personal and effective residence.

Secondary residences, holiday homes and properties intended for rental or commercial use are generally not eligible.


Occupancy conditions

To benefit from the Bëllegen Akt, the buyer must personally and effectively occupy the property.

The property must be occupied:

  • within 2 years from the date of the notarial deed;
  • within 4 years when buying a building plot or a property under construction.

It must then be occupied continuously for at least 2 years.

In certain situations, an extension of the occupancy period may be requested from the AED with a written and justified request.


What happens if the conditions are not met?

If the conditions are not respected before the minimum occupancy period has been completed, the tax credit may have to be repaid in full, together with legal interest.

The buyer must also inform the Administration of Registration, Estates and VAT (AED) of any transfer or change in the use of the property within the required period.


How do you apply for the Bëllegen Akt?

The application is made by the notary when the notarial deed is signed.

The deed includes the buyer’s request and the commitments concerning the personal use of the property.

The tax credit can be used all at once. If the duties due on a purchase are lower than the available tax credit, the remaining amount may, under the applicable conditions, be used for future acquisitions until the credit has been fully used.


The 3% VAT rate

A reduced VAT rate for creating or renovating a home

Luxembourg applies a super-reduced VAT rate of 3% to certain construction and renovation work for a property intended as a main residence, subject to the applicable conditions.

The standard VAT rate is 17%.

For eligible projects, the difference between the standard rate and the 3% rate can therefore represent a significant tax benefit.


A tax benefit of up to €50,000 per home

The total VAT benefit is limited to:

€50,000 per home created or renovated

This limit applies per property, not per buyer.


How does the 3% VAT rate work?

Depending on the project and the circumstances, the 3% VAT rate can be applied directly or obtained through a refund.

Direct application of the 3% rate

For eligible construction or renovation work, the 3% VAT rate can be applied directly when the required approval has been obtained from the AED.

The application must be made before the relevant work begins.

VAT refund

If the 3% rate cannot be applied directly, the buyer may, where the conditions are met, request a refund of the difference between the VAT paid and the 3% rate from the AED.

The total tax benefit remains limited to €50,000 per home created or renovated.


An important condition: main residence

The VAT benefit is linked to the use of the property as a main residence.

The property must meet the conditions set by the applicable VAT rules.

If a property is used both as a main residence and for another purpose, the tax benefit may be granted in full if the area used as the main residence represents more than three quarters of the total area. Otherwise, the benefit may be granted proportionally.

The benefit may have to be repaid if the property is no longer used as a main residence in circumstances covered by the rules.


Bëllegen Akt and 3% VAT: two different tax benefits

The Bëllegen Akt and the 3% VAT rate are two separate schemes.

The Bëllegen Akt is a tax credit that reduces the registration and transcription duties when purchasing a property. It can reach €40,000 per buyer, subject to the applicable conditions.

The 3% VAT rate applies to certain construction and renovation operations for a property intended as a main residence. The total tax benefit is limited to €50,000 per home created or renovated.

Each scheme has its own rules and eligibility requirements.


What should you check before buying?

When buying a property for your main residence, it is important to check:

✓ the registration and transcription duties
✓ your eligibility for the Bëllegen Akt
✓ whether the 3% VAT rate can apply to your project
✓ the occupancy conditions
✓ any other government assistance you may be entitled to

These tax benefits can represent a significant financial advantage and should be considered when preparing your overall financing plan.


Plan your purchase with confidence

Every situation is different. The taxes and benefits applicable to your purchase depend on the type of property, its intended use and your personal circumstances.

Your notary can calculate the exact taxes applicable to your purchase and check the conditions for the different tax benefits.

Housing Assistance in Luxembourg

Government support for your property purchase

The Luxembourg State offers several financial support schemes to help households buy or build their main home.

Depending on your income, household situation and the characteristics of your property, you may be eligible for a home ownership incentive, savings subsidy, interest subsidy or State guarantee.

Some of these schemes can be combined, subject to the conditions of each programme.


Home Ownership Incentive

Financial support for buying or building your main home

The Home Ownership Incentive (Prime d’accession à la propriété) is a financial contribution from the Luxembourg State for people buying or building a home in Luxembourg with a mortgage.

The amount depends on the income and composition of your household and can range from:

€500 to €10,000

For a semi-detached house, the incentive is increased by 15%.

For a terraced house or a property in a condominium, the increase is 40%.

The main conditions include:

  • the property must be located in Luxembourg;
  • it must be your main and permanent residence;
  • it must be financed with a mortgage;
  • you must meet the applicable income and household conditions.

You must normally apply within one year from the date of the notarial purchase deed or the VEFA deed.

The property must generally be occupied as your main and permanent residence for at least 2 years after the incentive is paid. If the property cannot yet be occupied when the incentive is granted, you have up to 3 years to move in.

An interesting benefit for semi-detached houses

For buyers of a qualifying semi-detached house, the 15% increase can provide an additional financial benefit.

This can be particularly relevant when preparing the financing of a new semi-detached house.


Savings Subsidy

Support for buyers who have built up savings

The Savings Subsidy (Prime d’épargne) may be available if you have saved money specifically to finance the purchase or construction of your home.

It can reach:

€5,000 per beneficiary

To qualify, you must have saved your own funds with the same financial institution for at least one year and invest at least 90% of the eligible savings in the financing of your home.

A maximum savings period of 10 years can be taken into account.

The subsidy corresponds to 10% of the increase in savings per calendar year, with a maximum of €500 per year.

The Savings Subsidy is linked to the Home Ownership Incentive: you must have received the Home Ownership Incentive and meet its conditions.


Interest Subsidy

Help with the cost of your mortgage

The Luxembourg State may provide an Interest Subsidy (Subvention d’intérêt) to reduce the monthly cost of a mortgage used to buy, build or improve a home that serves as your main and permanent residence.

The subsidy rate depends on your household income and composition and can currently range from:

0.25% to 3.50%

For the calculation of the subsidy, mortgage loans are taken into account up to:

€200,000

This amount is increased by €20,000 per dependent child, up to a maximum amount of:

€280,000

The exact amount of the subsidy depends on your personal circumstances and the conditions applicable to your loan.


State Guarantee

Additional support when financing your home

When applying for a mortgage, banks normally require financial guarantees, such as personal funds and a mortgage on the property.

Under certain conditions, the Luxembourg State can guarantee part of your mortgage loan.

The maximum State guarantee is currently:

€303,862

The guarantee can be used for a loan intended to purchase, build or renovate a home in Luxembourg, subject to the applicable conditions.

The bank providing the mortgage must have signed an agreement with the Luxembourg State allowing it to use this guarantee.

The property must become your main and permanent residence.

Specific conditions also apply regarding your savings and your ownership of other properties.


Energy-related assistance

The Luxembourg State also offers various financial support schemes for energy efficiency and renewable energy.

These schemes can support certain technical installations and energy-related improvements, depending on the type of project and the applicable technical requirements.

For a newly built home, it is important to check the eligibility of the specific equipment included in the project. Not every energy-related subsidy automatically applies to a new construction.

The applicable conditions may depend on the technology, the date of the work or order and the technical requirements in force.


Can these subsidies be combined?

Some housing assistance schemes can be combined.

For example, the Home Ownership Incentive can be combined with other capital subsidies, subject to the applicable conditions.

However, there is an overall limit for certain capital subsidies.

The total amount of the Home Ownership Incentive, Savings Subsidy, Improvement Subsidy and Energy Renovation Improvement Subsidy is currently limited to:

€35,000 per beneficiary

This limit applies to the capital subsidies covered by the scheme.

The State Guarantee and the Interest Subsidy are separate mechanisms and should not be confused with this capital subsidy limit.


Who can benefit?

Housing assistance is not automatically available to every buyer.

Your eligibility may depend on:

✓ your household income
✓ the composition of your household
✓ your personal and financial situation
✓ whether you own another property
✓ the type of property you are buying
✓ your mortgage
✓ and whether the property will be your main and permanent residence

Each subsidy has its own conditions and application procedure.


How do you apply?

Applications for the main housing assistance schemes are submitted to the Single point of contact for housing assistance (Guichet unique des aides au logement).

Some applications have specific deadlines. For example, the Home Ownership Incentive must generally be requested within one year of the relevant purchase or VEFA deed.

It is therefore advisable to check the applicable conditions before making your purchase and as early as possible in your financing process.

The Luxembourg government’s official housing portal also provides information, online services and appointment options for housing assistance.


Prepare your financing carefully

Government assistance can represent a significant contribution to your property project.

However, these subsidies should be considered as part of your overall financing plan, rather than as guaranteed funding.

Before making a commitment, we recommend checking your eligibility and discussing your financing with your bank or financial advisor.

Insurance & Guarantees

Protecting your home and your investment

Buying a new home is an important investment. Different types of insurance and legal guarantees can help protect you, your family and your property.

It is important to distinguish between insurance related to your financing and legal guarantees related to the construction of your home.


Outstanding Balance Insurance

Protecting your family in the event of death

Outstanding Balance Insurance (assurance solde restant dû) is designed to cover all or part of the remaining mortgage balance if the insured person dies, according to the terms of the insurance policy.

This type of insurance can provide important protection for your family by reducing or settling the remaining mortgage debt.

Depending on the financing solution, your bank may require this type of insurance.

The cost and coverage depend on factors such as:

  • the amount borrowed;
  • the duration of the loan;
  • your age;
  • your health and personal situation;
  • and the level of coverage selected.

Your bank or insurance provider can explain the available options and the conditions of the policy.


Insurance linked to your financing

When arranging a mortgage, the bank may require certain guarantees or insurance depending on your financial situation and the loan.

The exact requirements can vary from one bank to another.

We recommend checking these requirements early in the financing process so that the related costs can be included in your overall budget.


Construction Guarantees

Legal protection for your new home

When buying a newly built property, Luxembourg law provides specific legal responsibilities for construction defects.

These responsibilities depend on the type and nature of the work concerned.

For major works, the seller-constructor is generally liable for 10 years from the acceptance of the property, and in certain cases the period can be longer. Major works may include structural elements, the roof, certain external walls, foundations and other important parts of the building.

For minor works, the liability period is generally 2 years from acceptance. These may include certain interior elements such as woodwork, doors, window frames, radiators or wall finishes.

The exact legal responsibility depends on the nature of the defect and the part of the building concerned.

The 10-year guarantee

The term “10-year guarantee” is commonly used to describe the liability period applicable to major works.

It is important, however, to understand that this is a legal construction liability, rather than simply an insurance policy covering every problem that may occur during ten years.

The applicable rules depend on the type of defect, the work concerned and the circumstances of the case.

The 2-year guarantee

For minor works, the legal liability period is generally 2 years from the acceptance of the property.

This may cover certain non-structural elements of the building.

If you identify a defect after moving into your home, it is important to report it promptly and keep a written record of the issue and any communication concerning its repair.


The completion guarantee

When buying a property under construction through a VEFA, the sales contract must include the guarantee of completion of the building.

This guarantee is designed to protect the buyer if the developer is unable to fulfil its obligation to complete the project, according to the conditions set out in the guarantee and the contract.

Under the conditions provided by law, a refund guarantee may also be used instead of a completion guarantee.

This protection is one of the important features of buying a property under VEFA in Luxembourg.


The acceptance of your property

The acceptance of the property is an important stage in the purchase of a new home.

It allows the buyer and the developer to check the condition of the property and, where necessary, record any defects or outstanding items.

We recommend keeping the acceptance report and all documents relating to any subsequent repairs or interventions.

The date of acceptance is also an important reference point for the legal construction responsibilities described above.


Several levels of protection

When buying a new home, several forms of protection may apply:

Financing
→ mortgage guarantees and, where applicable, outstanding balance insurance.

Construction
→ legal responsibilities for major and minor works.

VEFA
→ completion or refund guarantee, according to the applicable legal and contractual arrangements.

Acceptance
→ a formal record of the condition of the property when it is handed over.

Together, these mechanisms provide an important level of protection for the buyer of a new property.


At Trend House

At Trend House, we believe that buying a new home should be a clear and transparent process.

We provide our buyers with the documents relating to their property and remain available throughout the different stages of the project.

A new home is more than a purchase. It is an investment in your future.

Energy Performance

A more comfortable home, with lower energy needs and built to last

Energy performance is an essential part of a new home. It affects energy consumption, indoor comfort and the overall quality of the building.

A high-performance home combines several elements: good insulation, airtight construction, high-performance windows, efficient heating systems and, depending on the project, the use of renewable energy.


Understanding energy ratings

In Luxembourg, the energy performance of a building is assessed through its Energy Performance Certificate (EPC), also known as the Energy Passport.

The Energy Passport provides different ratings that show the building’s energy performance.

It takes into account factors such as:

  • primary energy consumption;
  • the energy performance of the building;
  • heating requirements;
  • CO₂ emissions;
  • the characteristics of the building envelope;
  • and the technical systems installed.

The better the energy rating, the higher the level of energy efficiency of the building.


A high-performance building envelope

The first step towards good energy performance is to reduce heat loss.

A well-designed building envelope combines:

✓ effective thermal insulation
✓ good airtightness
✓ high-performance windows
✓ high-performance glazing
✓ a design that helps reduce thermal bridges

The aim is simple: to keep heat inside during winter and limit overheating during summer, while maintaining a comfortable indoor environment.


Comfort in every season

Energy performance is not only about reducing energy consumption.

A well-insulated and properly designed home can also provide greater everyday comfort.

A high-performance building envelope can help to:

  • maintain a more stable indoor temperature;
  • reduce the feeling of cold walls;
  • limit drafts;
  • improve comfort during winter;
  • reduce heating needs;
  • improve comfort during hot periods.

Energy performance therefore contributes directly to the quality of life inside the home.


Efficient energy systems

Technical systems also play an important role in the overall performance of a home.

Depending on the project, new homes may include solutions such as:

Heat pump

A heat pump efficiently provides heating by using energy from the outside environment.

It is particularly well suited to modern, energy-efficient new homes.

Low-temperature heating

Combined, for example, with underfloor heating, a low-temperature system distributes heat evenly throughout the home while operating at relatively low water temperatures.

Mechanical ventilation

In highly energy-efficient and airtight buildings, properly designed ventilation helps maintain good indoor air quality and control humidity.

Depending on the project, a ventilation system with heat recovery can also help reduce energy losses caused by air renewal.


A complete approach to energy performance

Energy performance does not depend on a single piece of equipment.

It results from the combination of several elements:

Insulation + airtightness + high-performance windows + orientation + efficient technical systems + ventilation

This overall approach helps create a home that is both energy-efficient and comfortable to live in.


Energy performance and running costs

An energy-efficient home generally requires less energy to maintain a comfortable indoor temperature.

This can help reduce energy costs, although actual consumption always depends on how the home is used, the desired indoor temperature, the occupants’ habits and weather conditions.

It is therefore important to distinguish between the building’s calculated energy performance, as shown in the Energy Passport, and its actual energy consumption, which depends on how the home is used.


An investment for the future

Energy performance is also an important factor in the long-term value of a property.

Energy requirements are evolving, and buyers are increasingly paying attention to:

  • energy costs;
  • thermal comfort;
  • indoor air quality;
  • the use of renewable energy;
  • the quality of the building envelope;
  • and the environmental impact of the home.

Choosing an energy-efficient new home therefore also means anticipating the expectations and requirements of tomorrow.


At Trend House

At Trend House, we pay particular attention to the quality of the building envelope, energy efficiency and the comfort of the occupants.

Each project is designed according to its specific characteristics, its location, its architecture and the energy requirements that apply to it.

The exact performance of each property is shown in its Energy Passport and in the technical documents for the project.

An energy-efficient home is, above all, a home that is comfortable to live in.

Discover our projects and their energy performance.

The energy performance, equipment and technical features vary from one project to another. The information on this page is general and does not replace the Energy Passport or the technical documents relating to each property.

The Steps in Your Purchase

From your first visit to receiving the keys

Buying a new home is an important step. At Trend House, we want to support you throughout your project and provide clear information about the property, its features, the purchase conditions and the progress of the construction.

Here are the main steps involved in buying a new property.


1. Discover your future home

Everything starts with discovering the project.

The plans, floor areas, location, architecture, specifications, equipment and energy performance allow you to get a clear idea of your future home.

For each project, the available documents provide detailed information about the property and the features included.

When buying off-plan, the plans and specifications are particularly important documents to review before making a commitment.


2. Plan your budget

Before committing to your purchase, it is important to determine your financing capacity.

Your budget should take into account:

  • the purchase price;
  • acquisition costs;
  • your personal contribution;
  • your mortgage;
  • any options or upgrades;
  • and any government assistance you may be entitled to.

Your bank or financial advisor can help you prepare a financing plan based on your personal situation.


3. Reserve your property

Once you have chosen your future home, a reservation may, depending on the project, allow you to formally express your interest in the property.

The terms and conditions of the reservation depend on the project and the contractual documents involved.

For a VEFA purchase, the preliminary contract and the notarial deed are subject to specific legal rules. It is therefore important to carefully review the documents before signing.


4. Prepare your purchase with your notary

The purchase of a property is formalised through a notarial deed.

Your notary checks the legal aspects of the transaction and prepares the deed required to complete the purchase.

For a property under construction, specific documents and information are required, including the plans and specifications and, where applicable, the documents relating to the co-ownership.

Your notary is your main contact for any legal questions regarding the purchase.


5. Sign the sales deed

For a VEFA purchase, the notarial deed sets out the main terms of the purchase, including the property, its price, the payment schedule, the expected delivery date and the applicable conditions.

The ownership of the land and the building is transferred according to the rules applicable to VEFA, while the future parts of the building become the buyer’s property as construction progresses.

Payments are made progressively according to the progress of the works and the terms of the sales deed.


6. Follow the progress of the construction

Once construction begins, your future home gradually takes shape.

Depending on the project and its stage of construction, you may have the opportunity to make certain choices regarding finishes or personalisation.

Payments are made according to the terms set out in the sales deed and the progress of the works.


7. Prepare for your move

As the construction nears completion, it is time to prepare for your move.

This is the right time to:

  • organise your move;
  • arrange your home insurance;
  • plan any furniture or interior work;
  • arrange the contracts and services for your new home;
  • prepare your change of address.

For properties in a co-ownership, you will also receive the relevant information concerning the common areas and the management of the building.


8. The handover and acceptance of your home

Once the property is completed, the acceptance of the property takes place.

This allows you and the developer to check the condition of the property and, where necessary, record any defects or outstanding items.

It is important to keep the acceptance report and any documents relating to subsequent work or repairs.

The acceptance date is also an important reference point for the legal guarantees and construction responsibilities that apply after delivery.


9. Receiving the keys

Once the conditions for delivery have been met, the keys to your new home are handed over to you.

You can then take possession of your house or apartment and begin a new chapter in your life.

Your new home is ready for you.

Property Purchase Documents

The key documents for your new home

Buying a new property involves several important documents. Each one has a specific purpose and helps you understand the characteristics of your future home, the features included, the purchase conditions and the building’s energy performance.

Taking the time to review these documents before signing helps you have a clear understanding of what you are buying, what is included in the price and what each party is responsible for.


The plans

The plans allow you to visualise your future home and understand how it is organised.

They show, among other things:

  • the layout of the rooms;
  • floor areas;
  • main dimensions;
  • doors, windows and access points;
  • the location of equipment;
  • terraces, balconies or private gardens;
  • parking spaces and garages, depending on the project.

For an off-plan purchase, the plans are an essential document for understanding the property before construction is completed.

The contractual plans should be reviewed together with the specifications and other sales documents to understand exactly what is included.


The specifications

The specifications describe the materials, equipment, installations and finishes planned for the property.

They may include details about:

  • floor and wall finishes;
  • doors and windows;
  • bathroom fittings;
  • heating;
  • ventilation;
  • electrical installations;
  • kitchen equipment, when included;
  • outdoor areas;
  • façade materials.

This document helps you understand what is included in the purchase price and what may be available as an option or upgrade.

An important document to review

For an off-plan purchase, the specifications are particularly important. They should be read together with the plans and the sales deed.


The Energy Performance Certificate

The Energy Performance Certificate (EPC), also known as the Energy Passport, provides information about the energy performance of the building.

It allows you to understand the energy characteristics of the property and its technical systems.

The Energy Passport shows the energy ratings of the building and the information used to determine its energy performance.

For a new property, it is therefore an important document for understanding the building’s energy efficiency.

Actual energy consumption may nevertheless vary depending on how the property is used by its occupants.


The notarial deed

The notarial deed is the legal document that formalises the purchase of the property.

For a VEFA purchase, the deed sets out the main terms of the transaction, including:

  • the identification of the property;
  • the purchase price;
  • the payment schedule;
  • the expected delivery date;
  • the planned features and specifications;
  • the applicable guarantees;
  • and the other contractual conditions.

The notarial deed is one of the most important documents in your purchase and should be carefully reviewed before signing.

Your notary is your main contact for any legal questions regarding its content.


The completion guarantee

For a VEFA purchase, Luxembourg law provides for a completion guarantee or, under the conditions provided by law, a refund guarantee.

The completion guarantee is intended to protect the buyer if the seller is unable to fulfil its obligation to complete the building, according to the terms of the guarantee and the applicable law.

The document relating to this guarantee is therefore an important part of the purchase documentation.


Co-ownership documents

When your property is part of a residence or building with several owners, you will also receive documents relating to the co-ownership of the building.

These documents define, among other things:

  • the private areas;
  • the common areas;
  • the ownership shares;
  • the rules applying to the use of the common areas;
  • and the rights and responsibilities of the co-owners.

The co-ownership regulations set out the rules for the management and use of the building.

These documents are particularly important for understanding your responsibilities and obligations as a future owner.


The acceptance report

Once construction is completed, the acceptance of the property takes place.

An acceptance report records the condition of the property at the time it is handed over and, where necessary, lists any defects or outstanding items identified during the inspection.

This document is important because it provides a record of the condition of the property when it was accepted.

It should be kept together with the other documents relating to your purchase.

The acceptance date is also an important reference point for the legal guarantees and construction responsibilities that apply after delivery.


Keep your documents safely

We recommend keeping all documents relating to your property, including:

✓ the notarial deed
✓ the plans
✓ the specifications
✓ the Energy Passport
✓ the guarantee documents
✓ the co-ownership documents, where applicable
✓ the acceptance report
✓ documents relating to any repairs or work carried out after delivery

These documents may be useful throughout the life of your property, particularly when carrying out work, requesting repairs or selling the property in the future.


Additional documents depending on your project

Not every property purchase involves exactly the same documents.

The documents provided may vary depending on the type of property, the purchase process, whether the property is part of a co-ownership and the specific characteristics of the project.

The contractual documents for each project are the reference documents for determining the exact features, specifications and obligations that apply.


Clear information for your purchase

At Trend House, we want every buyer to have the information they need to understand their future home and the conditions of their purchase.

Plans, specifications, energy documents and contractual documents together provide a clear picture of your future property.
