A first purchase goes wrong in predictable ways, and almost all of them come from doing the right things in the wrong order. What follows is the sequence we would use.
1. Fix the total budget before you look at anything
Not the asking price you can afford, the total you can afford. That means the price plus registration and transcription duties at 7 per cent, less whatever Bëllegen Akt credit you can genuinely claim, plus notary fees in the region of 1 to 1.5 per cent, plus a valuation, plus insurance from the date of the deed, plus moving. Write the number down. Every subsequent decision refers back to it.
Two people buying together should establish early whether the deed will record a joint acquisition in indivision, because that structure is what allows both individual tax credits to be used.
2. Get written pre-approval from more than one bank
A verbal indication is not a pre-approval. Ask for it in writing, from at least two lenders, and compare more than the headline rate: the fixed-rate period, the early-repayment terms, the required contribution and whether the offer is conditional on moving your salary account. Residents are commonly asked for 10 to 20 per cent of the price as a contribution; non-residents are frequently asked for 20 to 30 per cent.
Do this before viewings, not after. In a tight market the seller who receives two comparable offers takes the one that looks financeable, and a written pre-approval is what makes yours look that way.
3. Choose the commune before the property
Luxembourg City, the surrounding communes and the cross-border options represent genuinely different trade-offs in price, space, schooling and commute, not simply different postcodes. Decide which trade-off you are making before you fall in love with a floor plan, because a good property in the wrong commune is a decision you live with every weekday morning for a decade.
Test the commute in person, at the real hour, in both directions. Twenty minutes at eleven in the morning and forty-five at eight are the same road.
4. View properly
Go twice, at different times of day. Look at what does not photograph: storage, the entrance and stairwell, the state of the common areas, where the bins go, natural light in the rooms you will use in the evening, noise from the street and from the building itself, and the last five minutes of the walk home after dark.
In an apartment, ask about the heating system and its age, the energy performance certificate, the insulation and windows, whether the building has a lift and what the annual service charge actually covers. In a house, add the roof, the boiler, the electrics and any structural work in the last twenty years.
5. Read the co-ownership file before you offer
For an apartment this is the step most first-time buyers skip and most experienced buyers insist on. Ask for the last three years of service-charge accounts, the reserve-fund position and the minutes of the last two general meetings. You are looking for a specific thing: work that has been discussed or voted but not yet paid for. A facade, a roof or a lift renovation agreed before your purchase becomes your bill after it.
Read the co-ownership regulation too. It governs what you may do with the property, including whether short-term letting is permitted.
6. Commission an independent valuation
On a shortlisted property, an independent valuation referencing actual transaction data rather than portal asking prices typically costs a few hundred to around 1,200 EUR. Against a purchase of several hundred thousand, it is inexpensive insurance, and it gives you something concrete to negotiate with.
7. Treat the compromis as the real commitment
The compromis de vente binds you. Everything you need must be in it before you sign, and the financing condition is the one that matters most: a clause suspending the sale if your mortgage is refused within a defined period. Also settle in the compromis what is included in the sale, the handover date, who bears which costs and the position on any work in progress.
Engage a notary early, ideally before you find the property. Notary involvement is mandatory and the notary verifies title and encumbrances, but the notary is not there to negotiate on your behalf. Understanding the document before you are asked to sign it under time pressure is your responsibility, and it is much easier to discharge in a calm week than in a rushed one.
8. The deed, and the two years that follow
At the notarial deed the balance is paid, the duties are settled, the credit is applied and the keys change hands. The Bëllegen Akt tax credit currently stands at 40,000 EUR per buyer, 80,000 EUR for a couple buying jointly, applied by the notary directly against the registration and transcription duties owed; a government proposal announced in July 2026 would raise this to 45,000 EUR per buyer, but it was still working through parliament at the time of writing, so confirm the figure in force with your notary rather than assuming the higher one applies. Whichever ceiling applies, remember the condition attached to it: the property must be occupied as your own primary residence, from possession or within two years. Letting it out instead means repaying the credit with interest. Our guide to the Bëllegen Akt covers the mechanics in full.
In the first month after the deed, set up the building insurance, register with the commune, take meter readings in writing and introduce yourself to the syndic. None of it is difficult; all of it is easier immediately than six months later.
The mistakes we see most often
Budgeting on the price rather than the total. Signing a compromis without a financing condition. Assuming a tax credit ceiling from an article rather than confirming it with the notary. Valuing a property from portal listings alone. Skipping the co-ownership accounts. And viewing once, in sunshine, at eleven on a Saturday.
None of these are exotic. They are simply the steps that feel optional when a market is moving quickly and a seller is applying pressure, which is exactly when they are worth most.
New-build and off-plan purchases
A significant share of what is on the market in and around Luxembourg City is sold off-plan, before or during construction. The structure is different from a resale: payment is staged against construction progress rather than settled in one instalment, and the contract carries completion guarantees and defect periods that a resale does not. A reduced VAT rate can apply to work on a primary residence, subject to authorisation and to a cap, and it is applied for rather than granted automatically.
Two questions are worth asking early on any off-plan purchase. First, what exactly is included in the finish, because the specification sheet, not the show apartment, is the contractual document. Second, what happens to your position if delivery slips, since a delay affects your rent, your notice period at your current address and your mortgage offer at the same time.
A realistic timeline
From first serious viewing to keys, a straightforward resale purchase in Luxembourg commonly runs two to four months, with the gap between the compromis and the deed accounting for most of it. An off-plan purchase runs to the construction schedule and can be a year or more. Plan your current lease around the real timeline rather than the optimistic one; three months' tenant notice is the figure to work back from.
Editorial note: Rates, tax credit ceilings and lending conditions change, and every transaction differs. This checklist is a framework, not advice on a specific purchase. Confirm current figures with your notary, your bank and the relevant authority.
