**Updated June 29, 2022 — Statistics up to Q1 2022.**
The house prices presented here are from **real estate advertisements** published in the daily and specialised press, and on the real estate portal [IMMOTOP.LU](http://www.immotop.lu/). These are in no way the selling prices actually paid by the buyers, but the **prices charged by the seller at the time of the sale of the property, prior to any negotiation**.
The Habitat Observatory distributes a series in current euros (in nominal value), as well as a series in **EUROS CONSTANTS**: constant prices are prices in real terms, i.e. adjusted for the change in consumer prices (reflected here by IPCN — STATEC National Consumer Price Index) in relation to a baseline or reference data. The constant euro series therefore describes the change in advertised prices for the sale of dwellings after taking into account inflation on consumer prices.
