The Complete Guide to Buying Property in Luxembourg: From Your First Search to Getting the Keys

Buying a property involves much more than visiting a few homes and signing a deed at the notary’s office. From defining your budget and finding the right property to viewings, mortgage approval and administrative formalities, there are several important steps to follow.
In this guide, we explain step by step how to buy a property in Luxembourg, helping you approach your real estate project with confidence and peace of mind.
1. Determine your budget
Before starting your property search, it is essential to determine your budget accurately. This will help you establish a realistic price range based on your financial situation, assess your borrowing capacity with a bank, determine the personal contribution you can provide and anticipate the additional costs associated with purchasing property in Luxembourg, such as notary fees, registration duties and potential banking fees.
Good financial preparation will allow you to approach your property purchase with confidence and avoid unpleasant surprises later in the process.
Iris tip: We recommend contacting your bank or a trusted financial institution to obtain a simulation of your borrowing capacity.
2. Start your property search
Once your budget has been clearly defined, you can start searching for your future property. In Luxembourg, several specialised real estate portals offer a wide selection of apartments, houses and plots of land for sale.
These platforms are an excellent starting point for comparing properties currently available on the market, refining your search criteria and identifying properties that match the budget established in step 1.
The most popular property portals include:
* atHome.lu
* Immotop.lu
You can also activate email alerts on these platforms to be notified as soon as a new property matching your criteria is published.
Iris tip: We also recommend contacting our team and sharing your search criteria with us. Thanks to our property portfolio and current sales mandates, we may be able to present certain properties before they are published on the major real estate portals, giving you an advantage over other potential buyers.
3. You have found a property you like: what next?
Before contacting the seller or real estate agency, take a few minutes to analyse the listing carefully. Read the complete property description, as some important information may not always appear correctly in the standard fields provided by property portals.
Take a closer look at the property's location and surroundings using tools such as Google Maps to get a first impression of the neighbourhood. Check whether nearby amenities, transport links and the general environment meet your needs.
Does the property match your criteria and can you already imagine yourself living there? The next step is simple: contact the real estate agency and arrange a viewing as soon as possible.
Iris tip: Whenever possible, contact the real estate agency by phone. A telephone call will often allow you to arrange a viewing more quickly than an email and can reduce the risk of another potential buyer visiting the property before you.
4. The viewing: one of the most important steps
Punctuality is important for both you and the real estate agent. Arriving on time ensures that everyone has enough time to view the property properly and discuss any questions.
Once there, the real estate agent will show you the property in detail. Pay close attention to the information provided and do not hesitate to ask questions. If anything is unclear, ask for clarification. It is essential to understand the property's characteristics before considering an offer.
Use the viewing to check whether the information in the listing corresponds to the property itself, particularly the living area, year of construction, materials, finishes and overall condition.
When viewing a house, ask about any renovation work that may be required or has already been completed. When buying an apartment in Luxembourg, it is highly advisable to request the minutes of the last three co-ownership general meetings. These documents may reveal planned or approved works, disputes or other important decisions concerning the building.
You should also ask about practical matters such as the property's availability, co-ownership charges, fixtures and equipment included in the sale, and any potential easements affecting the property.
Having this information will help you assess the property properly and make an informed decision.
Iris tip: Ask the real estate agent which property documents are available before making your final decision.
5. The viewing went well and you want to buy
If the property meets your expectations, the next step is usually the sale agreement, known in Luxembourg as the *compromis de vente*.
The sale agreement formalises the agreement between the seller and the buyer. It contains the essential terms of the transaction, including the final purchase price, details of both parties, an exact description of the property, any conditions precedent such as obtaining mortgage financing, the expected deadline for signing the notarial deed, the choice of notary and the agreed date for taking possession of the property.
Once signed, the sale agreement legally binds both parties. It is therefore essential to read it carefully and ensure that all agreed conditions have been correctly included before signing.
Iris tip: Take the time to choose your notary carefully. The notary's role is to ensure the legal security of the transaction and answer your questions through to the signing of the authentic deed. Make sure you fully understand every clause before committing yourself.
6. Obtaining your mortgage approval
Once the sale agreement has been signed, it is time to finalise your financing. Send your bank all the documents required to prepare and assess your mortgage application.
As part of its assessment, the bank will generally review your financial and professional situation, income, personal contribution, signed sale agreement and documents relating to the property.
Once your financing has been approved, inform your real estate agent that you have received your mortgage approval. We also recommend sending a copy by email as soon as you receive it.
This is an important step because it allows the agent to complete the transaction file and forward it to the notary. The notary can then prepare the authentic deed and arrange a signing date with all parties.
Iris tip: Do not limit yourself to your usual bank. Contact several banks or financial institutions and compare their mortgage offers. Look beyond the interest rate and consider application fees, early repayment conditions, possibilities for renegotiating the loan, insurance and other associated services. A thorough comparison can result in significant savings over the lifetime of your mortgage.
7. The notary and the handover of the keys
The big day has finally arrived.
Once the file has been prepared, the notary normally sends the parties a draft of the authentic deed a few days before the signing. This gives everyone the opportunity to review the document carefully and ensure that the terms agreed in the sale agreement have been correctly reflected.
On the day of the appointment, the parties meet at the notary's office to sign the authentic deed. The notary reviews the main provisions, explains the relevant clauses and answers any remaining questions.
After the deed has been signed and the purchase price paid, the transfer of ownership is officially completed: you are now the owner of your new property.
Then comes the moment most buyers have been waiting for: receiving the keys.
Depending on the terms agreed in the sale agreement, the keys may be handed over immediately after signing the authentic deed or on another date agreed between the seller and buyer. This marks the end of several weeks or months of searching and administrative procedures – and the beginning of a new chapter.
Iris tip: Arrange your home insurance before signing the authentic deed. In most cases, the policy should be effective from the day you become the owner. When receiving the keys, make sure you receive all keys, access badges, remote controls, access codes and relevant property documents, including manuals, warranties and plans. You should also record the water, gas and electricity meter readings immediately after the handover.
