What Property - Fact-check any UK property listing before you book a viewing
by•
Click the button on a Rightmove, Zoopla or OnTheMarket listing. It checks the asking price against Land Registry sales, the EPC register, local rents and council HMO rules, then tells you if it works as a buy-to-let, HMO, flip, BRRR or holiday let, and when to walk away.

Hi Product Hunt 👋 I'm Ryan, a UK landlord and the maker of What Property.
Every listing says "great investment". I built a Chrome extension that checks if it's true, right on the listing:
🔍 Asking price vs Land Registry sales, EPC, local rents and council HMO rules
🏠 Scored as a buy-to-let, HMO, flip, BRRR and holiday let, in seconds
🚦 A straight verdict, including when to walk away
🤖 Also works inside Claude, ChatGPT & Grok

UK only for now, as it runs on UK data.
What's the first thing you check on a listing? I'll be here all day 🙏
