Statbel’s figures have two breaks: in 2005 the administrative source behind the statistics changed (transaction counts shift, most visibly in Brussels), and in 2010 the classification moved from the nature of the deed to the cadastral nature of the property. Segments on either side of a break are not strictly comparable. Prices are medians in euros of the day, not adjusted for inflation.

Getting a property valued in Onhaye
The medians above describe the Onhaye market as a whole, not one specific home: size, condition, the EPC score and even the street can move an individual price well away from the middle of the market.
To value a specific house or apartment, immetrics starts from its Immoweb listing, compares it with similar homes for sale and with the official sale figures for the area, then returns a documented price verdict. The first report is free, and it works on your own listing too if you are selling.
