London property data, quotable and checked

WhereToLive.xyz is an independent London property data project founded by Troy Tang. For the press we work from HM Land Registry Price Paid Data, and every figure comes with the method, sample size and caveats attached, so it survives your fact-check.

Data Notes

• London Data Note #2 · More London Homes Are Selling for Less Than the Owner Paid · 2026-10-06

What we can pull from

• About 4.0 million HM Land Registry sales in London's 33 boroughs since 1995
• Resales paired with the same home's previous sale: gains and losses by purchase year, property type, new build vs second-hand
• Cuts by borough and postcode district, with sample sizes shown

House rules

• Every figure ships with its methodology: medians over means, sample sizes stated, known limits flagged (see Methodology)
• Data, not takes: Data Notes and data pages take no policy position and make no market calls (the commentary pieces elsewhere in Insights are separate from them)
