Where these numbers come from
The source is the Property Price Registry (RCN) — prices from signed notarial deeds, maintained by county geodesy offices. Medians use market transactions only: fractional shares, tenders, foreclosures and discounted sales are excluded. The registry publishes deeds with a lag of weeks, so months that are not yet complete are left out of the tables entirely — data runs to the last full month.
