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.
