Frequently asked questions

Each entry links sales by the address and property type from Land Registry, with two registered sales at least two years apart. The latest sale was in the last 12 months. Prices are nominal — not adjusted for extensions, condition, or inflation. We show listings with archived photos and floorplans where available (15 snakes, 15 ladders).

A fall is not always a market crash story. Land Registry data input errors, Lease or title changes, part ownership, mis-matched addresses can all influence the numbers. This is not analysis nor is it investment advice, just a bit of fun.

We link sales based on the address and property type provided by Land Registry. We then compare the latest sale to the immediately previous registered sale on that address.
