Buying Guide

Judging an asking price in Luxembourg before you make an offer

Price per square metre is where most buyers start and it settles almost nothing, because in a co-ownership two apartments at the same rate can carry very different obligations attached to the building behind them.

Make the surfaces comparable first

Before any comparison is meaningful, strip the headline figures back to habitable surface. Luxembourg listings mix total surface, habitable surface, terraces, balconies, cellars and parking lots, and a property advertised at 110 m² including a 15 m² terrace and a 10 m² cave is an 85 m² apartment. Running a price per square metre on unnormalised numbers produces a comparison that is wrong before it starts.

Then adjust for what the rate conceals: floor level and lift, orientation, the proportion of surface consumed by circulation, ceiling height, whether a parking lot is included, and the size of the cave. Two apartments at €11,000 per square metre, one on a fourth floor without a lift facing north, are not the same purchase.

The second price, which is the building

A buyer in a copropriété acquires a share of common parts expressed in millièmes and a set of collective obligations. Three documents put a number on them.

The reconciled charges accounts for two completed years, which show what the building actually costs to run rather than what the monthly provision suggests. The minutes of the last three general assemblies, which show what has been voted, what has been postponed and what is being argued about. And the balance and annual contribution of the fonds de travaux, compulsory in every Luxembourg co-ownership since 1 August 2023 and set at a floor per square metre of energy reference surface graded by the building's insulation class.

An apartment priced 5% below a comparable one, in a building with a thin fund and a facade approaching renovation, is not cheaper. It is the same price with the invoice deferred and the timing decided by other owners.

Acquisition costs, and how they distort comparisons

Duties are 7% of the price, being 6% registration and 1% transcription, with regulated notary emoluments of roughly 1% to 1.5% plus VAT, disbursements and any mortgage deed on top. Against the duties sits the Bëllegen Akt: €40,000 per buyer and €80,000 for a couple acquiring together, permanent since July 2025, conditional on personal occupation as principal residence from entry into possession or within two years, with a minimum €100 of duty always payable.

Because the credit is a fixed amount rather than a percentage, it changes the shape of the comparison. On a €500,000 apartment bought by a couple with full credit available, €35,000 of duty is entirely absorbed. On a €1,200,000 property, €84,000 of duty is only partly absorbed. The effective cost of acquiring rises with the price in a way the headline rate does not show, and it is the single most common omission we see in buyers' spreadsheets.

Total acquisition costs commonly land between roughly 8% and 13% of the price for owner-occupiers after the credit, and materially higher for investors, who cannot claim it at all.

What the energy class now does to value

The energy passport used to be a running-cost indicator. It is now also a financing variable: properties classed A to C tend to attract the best lending conditions, while F to H generally triggers a stricter analysis with the necessary works folded into the financing plan.

That has two effects on price. It narrows the pool of buyers who can finance a poorly performing property, which is a negotiating argument. And it means the works are not optional in the way they once were, because a lender may require them to be budgeted rather than deferred.

The same logic runs at building level through the compulsory works fund, whose minimum contribution is graded by the building's thermal insulation class. A poorly insulated building is a higher standing obligation, by law, than a well-insulated one.

Building the offer

Three numbers, kept separate:

• The price, benchmarked on normalised surface against genuinely comparable properties in the same district, adjusted for floor, lift, orientation and parking.
• The acquisition cost, calculated with your actual Bëllegen Akt position rather than a generic 7%, and remembering that these costs are normally excluded from the financing and must come from your own funds.
• The building liability: known voted works, the state of the fund, and any arrears.

Present the offer on the price alone, and use the third number as reasoning rather than as an arithmetic deduction. A quotation from a named trade or a line in the assembly minutes is an argument. A general observation that the building looks tired is not, and sellers here have heard it.

Three questions we are asked

How much below asking is realistic? It depends entirely on how long the property has been listed and on whether its energy class narrows the buyer pool. Time on market and financing friction are the two things that actually move a Luxembourg seller.

Should I get a valuation? Your lender will require one, and it is done for the bank rather than for you. If the decision is finely balanced, an independent view is money well spent.

Is it worth offering on two properties at once? No. An accepted offer in Luxembourg leads to a compromis de vente, which is a binding contract with no general cooling-off period. Treat an offer as a commitment, because that is what it becomes.

What the transaction costs mean for holding period

Acquisition costs in Luxembourg are front-loaded, and that changes the arithmetic of a short hold more than most buyers expect.

An owner-occupier paying somewhere between 8% and 13% of the price to acquire needs the property to appreciate by roughly that amount, plus selling costs, simply to break even in nominal terms. On a five-year horizon in a flat market, that is a real risk rather than a theoretical one. On a fifteen-year horizon it is close to irrelevant.

Two adjustments follow. If your assignment in Luxembourg is genuinely open-ended, the arithmetic of buying is strong, particularly with a full Bëllegen Akt credit absorbing the duties. If there is a realistic chance of leaving within three or four years, renting and investing the difference deserves an honest comparison rather than a dismissal, because the transaction friction here is substantial in both directions.

The same logic argues for weighting resale characteristics in the offer: floor level and lift, a second bedroom rather than a large single one, parking, and an energy class that does not narrow the future buyer pool. Those features cost money now and they determine how quickly you can exit later.

Where the negotiating leverage actually is

Three factors move a Luxembourg seller, and none of them is enthusiasm.

Time on market. Ask how long the property has been listed and whether the price has already been reduced. A listing that has run for months in a district with normal turnover has a reason, and identifying it is more productive than guessing at a discount.

Financing friction. A poor energy class narrows the pool of buyers who can finance the property without folding works into the loan. That is a real constraint on the seller's market, and it is a legitimate argument supported by the passport rather than by opinion.

Documented liability. Works voted at the general assembly and not yet called for are an existing obligation attaching to the lot. A line in the minutes is an argument; an impression that the building looks tired is not.

Present the offer on price alone and keep the reasoning separate. Once an offer is accepted it leads to a compromis de vente, which is binding, so the moment to be rigorous is before rather than after.
