The property alone, rounded to the nearest thousand. On top of it come the transfer costs — registration and transcription duties plus the notary — which the mortgage does not finance and which therefore have to be in cash.
Buying against renting
12.2 years of rent
The purchase price of a 70 m² flat divided by a year's rent on the same 70 m². Under 20 years the market prices buying roughly like renting; past 30 it is pricing something else — an expected capital gain, or the scarcity of land. The two figures come from different sources, so the ratio is an order of magnitude rather than a yield calculation.

These are registered transaction prices, not asking prices: what was signed, not what was wanted. The gap between the two widens when the market slows, which is why these figures do not belong next to a property portal's.
Luxembourg publishes an average, France a median — on a tight market the two converge, on a long-tailed one the average sits higher. Every figure carries its method right beside it, and a comparison across the two countries has to allow for that.
Why 64 communes out of 127
Luxembourg publishes a commune-level price for apartments only: a house is too heterogeneous to average over a commune of 3,000 people, so the Observatoire de l'Habitat stops at the national level for them. Communes under ten transactions in twelve months are not published either — 60 of the 100 Luxembourgish communes clear that threshold.
On the French side, Moselle, Bas-Rhin and Haut-Rhin run the livre foncier rather than the cadastre, and are absent from DVF, the property-sales register. Longwy and Villerupt therefore have a price and Thionville and Metz have none — not an oversight, the data does not exist.
Belgium publishes its municipal prices in a separate statistical cube and Germany leaves them to each Land's valuation board. The 13 Belgian and German communes in the perimeter are left without a price rather than given an estimate.
