Investing in luxury real estate in Luxembourg: the wealth guide

Why Luxembourg, for a wealth investor

Luxembourg''s residential market is one of Europe''s most defensive and one of the least commented. A small territory, land rationed by municipal master plans, twenty years of positive net demography, a reserve currency, explicit taxation: the combination produces an asset that, over a long cycle, compares favourably to a core sovereign-bond allocation — with patrimonial optionality on top.

The Observatoire de l''Habitat published its note no. 31 in 2025: after a low point reached mid-2024, prices per m² stabilised and then resumed an upward trajectory on Luxembourg City''s premium residential segment. This inflection is not yet visible in the aggregate statistics, which blend new-build, existing stock, periphery and capital — but it is visible district by district for anyone who reads the notarial deeds.

Three addresses that always resell

Belair — the academic address

Belair is the historic address of established families and the liberal professions. Tree-lined avenues, international schools within a ten-minute walk, the Merl park on the edge, low traffic density. The median price per m² holds above €14,000/m² for renovated existing stock and above €17,000/m² for luxury-finish new-build. A Belair apartment always resells — it is the asset on which a wealth buyer accepts to pay the liquidity premium.

Limpertsberg — walkability and the view

Limpertsberg combines proximity to the city centre (a ten-minute walk from the Glacis), unobstructed views over the Alzette valley and a stock of often-recent quality apartments. South-facing penthouses with terrace trade at €18,000–22,000/m². Buyer profile is mixed: European executives on long relocations, central-European family-office vehicles, Luxembourg liberal professions.

Kirchberg — institutional new-build

Kirchberg is not a historic residential district — it is an office and EU-institutions district that residential promoters started investing seriously from 2018 onwards. For an investor, the interest is threefold: recent new-build (hence low energy-upgrade costs), immediate proximity to European employers (Commission, Court of Auditors, European Investment Bank), and a furnished rental product that holds at €4,000–5,000 monthly on a three-bedroom unit.

Taxation: what to understand before signing

Luxembourg real-estate taxation is one of the most readable in Europe. Three levers to know:

1. Acquisition duties. Registration duty is 6% plus 1% transcription duty, i.e. 7% of the purchase price. A resident benefits from the Bëllegen Akt rebate (a per-person capped tax credit on registration duties) provided they occupy the property as their primary residence for at least two years. A non-resident or buy-to-let investor pays the full rate.

2. Capital-gains taxation. Article 99ter LIR distinguishes speculative gain (< 2 years: taxed at the full marginal rate) and ordinary gain (≥ 2 years: taxed at 25% of the marginal rate, an effective rate often around 10–12%). A primary residence held more than two years is fully exempt.

3. No wealth tax on individuals. Luxembourg applies no wealth tax to individuals holding real estate directly. This is a structural difference with France, Spain or Switzerland for a real-estate portfolio.

Any corporate structure (French SCI, SPF, holding) must be discussed with a notary and tax counsel before signing the preliminary agreement. In the majority of purely Luxembourg patrimonial cases, direct acquisition remains the most efficient route.

Right timing: why 2025-2026

After two years of correction (2023-2024) during which prime prices retreated by 12 to 18% on certain brackets, the 2025-2026 window is the first since 2019 where a cash buyer holds real negotiating power. Patrimonial vendors are willing to discuss again, promoters have cleared unsold inventory, and ECB rates have begun their downward cycle. Our internal reading: re-premiumisation is already under way in Belair and Limpertsberg, the cycle will follow on Kirchberg in 12 to 18 months.

Discreet acquisition: why off-market

On the > €2M segment, the majority of transactions do not go through public portals. The reasons are threefold: protection of vendor privacy (often executives, liberal professionals, families known on the local scene), the wish to avoid stigma discount if the asset stays advertised too long, and controlled buyer selection. This is the natural ground for a boutique cabinet: a restricted portfolio, systematic financing qualification, viewings organised in discretion.

How EIRES Real Estate supports a wealth buyer

Our confidential search mandate runs in four steps: (1) wealth brief with the client and their counsel, (2) off-market screening across our portfolio and peer network, (3) financing qualification plus notary/tax coordination before any offer, (4) cash negotiation and closing. We handle around 50 sales per year on the premium segment and we hold the presidency of the Luxembourg Real Estate Federation — that dual anchoring is what grants access to real off-market, not a marketing promise.

If you are considering a wealth acquisition in Luxembourg, the starting point is a conversation, not a form. We meet at your home, at the property, or by video — never in agency premises.
