Mamer property market: prices, trend and buying costs in 2026
Apartments ask €9,518.7/m² in Q3 2026 — the first year-on-year rise since 2023 in Luxembourg's prime western commune.
CASAFARI Area Insights puts the average asking price of apartments in Mamer at €9,518.7 per m² in Q3 2026, calculated from indexed listings with outliers excluded rather than notarial transaction prices. At +0.6% on Q3 2025, this marks the first positive year-on-year reading after asking prices slid from €10,870.2/m² in Q1 2023 to €9,304/m² in Q4 2025. Located 8 km west of Luxembourg City with 11,583 residents (STATEC, 1 January 2026), Mamer requires buyers to budget for 7% registration duties, reduced on a primary residence by the €40,000 Bëllegen Akt credit per person.
When a couple arrives in Luxembourg for a post in Kirchberg or at the NATO Support and Procurement Agency in Capellen, colleagues inevitably offer the same piece of relocation advice: everyone with children ends up looking in Mamer. What newcomers discover next is a commune where a standard two-bedroom flat asks well over €800,000, and where a two-year market correction has just found its floor.
Where is Mamer, and why do buyers want to live there?
The commune sits directly on the western edge of the capital, roughly 8 km from the centre. It is made up of three distinct villages: Mamer itself (8,272 residents), Capellen (2,537) and the quieter rural hamlet of Holzem (772), according to Commune de Mamer figures from 31 December 2025.
Two transport corridors shape daily life. The A6/E25 motorway runs through the commune towards Brussels, and CFL line 50 stops at both Mamer and Mamer-Lycée stations, putting the Gare Centrale about fifteen minutes away on the country's free public transport network. Inside the commune, the Capellen business park concentrates thousands of corporate, technology and institutional jobs, while the Lycée Josy Barthel, the European School Luxembourg II and the Kinneksbond cultural centre anchor family life.
The demographic trajectory shows how steady that appeal has been. According to the Syvicol commune directory citing STATEC, the population reached 11,583 on 1 January 2026, up from 7,473 at the 2011 census and 10,426 in 2021 — a 55% expansion in fifteen years. Buyers weighing the western suburbs against the capital's quarters can compare both in our Luxembourg City guide and across the Luxembourg country guide.
How much does an apartment cost in Mamer in 2026?
In Q3 2026, apartments for sale in Mamer averaged €9,518.7/m² in asking price, according to CASAFARI Area Insights (location id 3692785, queried 23 October 2026). These figures represent asking prices from active and historical listings across portals and agencies, with statistical outliers excluded; they are not notarial sale deeds.
The quarterly series traces a clear correction and stabilisation across fifteen quarters:
- Q1 2023 high: €10,870.2/m² asking, just as higher European Central Bank interest rates began to bite into household borrowing capacity.
- Q4 2025 trough: €9,304/m² asking, a cumulative peak-to-trough decline of 14.4% across eleven quarters (nine quarterly declines and two brief pauses in Q1 and Q3 2024).
- 2026 stabilisation: roughly €9,356/m² in Q1 2026, €9,316/m² in Q2 2026, and €9,518.7/m² in Q3 2026 (+2.2% on the quarter).
For a practical benchmark, a 90 m² two-bedroom apartment priced at the Q3 2026 average comes to roughly €857,000 asking before negotiation.
Note that CASAFARI publishes only the apartment series for Mamer. Detached and semi-detached houses make up a large share of the residential stock in Mamer, Capellen and Holzem, but they trade in small numbers with wide variations in plot size and condition, so no house-price figure is quoted here.
Has the Mamer market turned?
Between Q1 2024 (the first quarter with a full year of lookback) and Q2 2026, Mamer recorded ten consecutive negative year-on-year readings in apartment asking prices, ranging between -1.7% and -8.0%. In Q3 2026, the year-on-year comparison turned positive at +0.6% (€9,518.7/m² against €9,460.6/m² in Q3 2025).
That puts the Q3 2026 level 2.3% above the Q4 2025 low, though still 12.4% below the Q1 2023 peak. In a commune of eleven thousand residents, a single quarter's move in asking prices can reflect the mix of units brought to market — a handful of newer energy-class A flats in Capellen will lift the mean. The disciplined reading is that Mamer has found a floor around €9,300–€9,500/m² asking, rather than entered a rapid new uptrend.
The national backdrop supports a view of gradual normalisation. According to the Observatoire de l'Habitat, Rapport d'analyse n°25 (Q1 2026), STATEC's hedonic transaction price index for all dwellings rose 0.7% on the quarter and 1.7% year on year in Q1 2026, while existing-apartment sales rose 9.4% year on year to 968 deeds.
How does Mamer compare with the rest of Luxembourg?
Setting Mamer against national figures requires separating asking prices from notarial deeds. In Q2 2026, the Observatoire de l'Habitat sale-price statistics recorded a national average transaction price of €7,795/m² for existing apartments (+1.3% on the quarter, -2.2% year on year) and €9,809/m² for apartments sold under construction (VEFA). Mamer's asking level of roughly €9,500/m² sits well above the national existing-apartment average, as expected for a first-ring western commune.
| Metric | Mamer (CASAFARI Area Insights) | Luxembourg national (STATEC / Observatoire de l'Habitat) |
|---|---|---|
| Data basis | Asking prices from indexed listings (outliers excluded) | Notarial transaction deeds |
| Q1 2026 price / m² (apartments) | €9,355.7/m² (all listed apartments) | — |
| Q2 2026 price / m² (apartments) | €9,315.6/m² (all listed apartments) | €7,795/m² existing; €9,809/m² VEFA |
| Q1 2026 year-on-year change | -1.7% (apartments asking) | +1.7% all dwellings; +0.9% existing apartments (hedonic index) |
| Q3 2026 price / m² (apartments) | €9,518.7/m² (+0.6% y/y) | Not yet published |
Why did Mamer still show -1.7% year on year in Q1 2026 when the national hedonic index was already at +1.7%? Two factors explain the gap. First, asking prices adjust on a different rhythm from completed deeds. Second, Luxembourg's high-value western belt stretched furthest during the low-rate cycle and took longer to clear seller expectations than mid-market communes in the North or East.

What does it cost to buy in Mamer: duties and the Bëllegen Akt
Every residential purchase in Luxembourg incurs registration and transcription duties (droits d'enregistrement et de transcription) totalling 7% of the purchase price — 6% registration plus 1% transcription — collected by the Administration de l'enregistrement, des domaines et de la TVA, as set out by Guichet.lu on the Bëllegen Akt tax credit (updated July 2025).
On our worked example of a 90 m² apartment at €857,000, the gross 7% duty comes to €59,990. For buyers who will live in the property themselves, the Bëllegen Akt (notarial deeds tax credit) offsets most or all of that bill:
- Standard credit (as of July 2025): up to €40,000 per natural person, or €80,000 for two buyers acquiring jointly, subject to effective personal occupation within the statutory deadline. A minimum flat duty of €100 always remains due.
- Worked example for a couple: on an €857,000 primary residence, two buyers with full unused credits cover the entire €59,990 duty bill, pay the €100 minimum duty, and retain €20,010 of combined credit for future use.
- Announced July 2026 increase: under the government's July 2026 housing package announcement (Booster fir de Wunnengsbau, 16 July 2026), the credit is scheduled to rise from €40,000 to €45,000 per person for acquisitions from 16 July 2026 onwards. The measure applies retroactively once voted by the Chambre des Députés, but was not yet enacted law as of October 2026; ask your notary how the pending credit is handled on your deed.
Notary fees, administrative disbursements and mortgage registration fees apply on top of the 7% duty. When reading market statistics across 2025 and 2026, bear in mind that temporary crisis tax incentives expired on 30 June 2025. That deadline pulled many signatures into the first half of 2025, which explains why national apartment transactions in Q2 2026 (1,274 sales) stood 33.9% below the inflated Q2 2025 figure of 1,928 sales (Observatoire de l'Habitat via Paperjam, Q2 2026).
Who buys in Mamer, and is it a market for investors?
Mamer is overwhelmingly an owner-occupier market. Domestic buyers tend to be Luxembourgish families trading an apartment in the capital for a house or larger garden flat, alongside international professionals from France, Belgium, Germany, Portugal, Italy, the UK and beyond working in finance, consulting, the EU institutions or at Capellen. Second homes play no meaningful role here.
Buy-to-let investors form a small minority, typically targeting one- and two-bedroom apartments within walking distance of Mamer or Mamer-Lycée stations for long-term corporate tenants. Because CASAFARI does not publish a separate rental series for Mamer, no commune-level gross yield is quoted here. Nationally, the STATEC rent index rose 1.4% between Q1 2025 and Q1 2026, while advertised apartment rents in listings climbed 4.4% over the same period (Observatoire de l'Habitat, Rapport d'analyse n°25, Q1 2026).
At an entry price above €9,500/m² asking, gross yields are structurally tight, and investors do not qualify for the Bëllegen Akt occupation credit (paying the full 7% duty). Moreover, the off-plan pipeline remains subdued: national VEFA apartment sales fell 18.2% year on year in Q1 2026 to just 207 units (Observatoire de l'Habitat, Q1 2026). Buyers analysing rental acquisitions can review what CASAFARI offers investors and price individual units with Comparables and the market study tools.
How to check Mamer prices yourself with CASAFARI
Every Mamer figure in this guide comes from location id 3692785, which you can resolve by querying "Mamer" in Location Lookup and passing the identifier into Area Insights. While the commune series gives the macro floor, pricing an individual flat on Route d'Arlon or in a quiet cul-de-sac in Holzem requires property-level evidence: Comparables matches a target unit against active and de-listed properties in the same micro-location.

Frequently asked questions
How much does an apartment cost in Mamer?
According to CASAFARI Area Insights, the average asking price for an apartment in Mamer reached €9,518.7/m² in Q3 2026 (based on indexed listings, outliers excluded). At that average, a standard 90 m² two-bedroom apartment asks roughly €857,000 before negotiation. Notarial transaction prices typically close below asking levels; across Luxembourg as a whole, the Observatoire de l'Habitat recorded an average transaction price of €7,795/m² for existing apartments in Q2 2026.
Are property prices in Mamer rising or falling in 2026?
Apartment asking prices in Mamer fell 14.4% between their Q1 2023 high (€10,870.2/m²) and their Q4 2025 trough (€9,304/m²), according to CASAFARI Area Insights. In 2026 the market has stabilised: Q3 2026 stood at €9,518.7/m², up 2.2% on the previous quarter and +0.6% year on year, the first positive annual reading since the series allows a comparison. Because a single quarter in a small commune can reflect listing mix, this should be read as a price floor rather than a confirmed uptrend.
What taxes and fees do I pay when buying a home in Mamer?
Buyers in Luxembourg pay 7% of the purchase price in registration and transcription duties (6% registration plus 1% transcription), alongside notary fees and mortgage registration costs (Guichet.lu, July 2025). If the property serves as your primary residence, the Bëllegen Akt tax credit reduces those duties by up to €40,000 per buyer (€80,000 for a couple buying jointly), leaving a minimum flat duty of €100 if the credit covers the full sum. On 16 July 2026, the government announced an increase of the credit to €45,000 per person with retroactive effect from that date, subject to a parliamentary vote.
Can a non-resident or non-EU national buy property in Mamer?
Prospective non-resident and non-EU buyers should confirm any specific administrative requirements for their status directly with a Luxembourg notary or on Guichet.lu before signing a compromis de vente. In practice, lending criteria and loan-to-value limits for non-residents vary significantly from one Luxembourgish bank to another. Furthermore, to claim the Bëllegen Akt tax credit against the 7% registration duties, the buyer must move in and occupy the property as an effective primary residence within the statutory timeframe.
How far is Mamer from Luxembourg City and how do people commute?
Mamer lies roughly 8 km west of central Luxembourg City. Residents commute in about 15 minutes either by car via the A6/E25 motorway or by train on CFL line 50 from the commune's two stations, Mamer and Mamer-Lycée, using Luxembourg's free nationwide public transport. Because the Capellen business park is located inside the commune, many residents also work locally without entering the capital.
Is Mamer a good buy-to-let investment?
Mamer is primarily an owner-occupier family market, with buy-to-let investors representing a small minority focused on one- and two-bedroom flats near the CFL stations. CASAFARI does not publish a rental series for Mamer, so no commune-level yield can be quoted, though nationally STATEC's rent index rose 1.4% and advertised apartment rents rose 4.4% between Q1 2025 and Q1 2026 (Observatoire de l'Habitat). With apartment asking prices averaging €9,518.7/m² in Q3 2026 and full 7% registration duties payable by non-occupiers, gross yields are more compressed than in lower-priced communes.
