About Nestfair: property valuations while you browse
Nestfair tells you whether a home's asking price actually stacks up, right there on the listing, before you make an offer.
Open any property for sale on Rightmove, Zoopla or OnTheMarket, click once, and you see:
• A valuation built from 31 million public sale records
• The likely price range, so you get honest uncertainty instead of one confident-looking number
• Down-valuation risk: how far the asking sits above the evidence, the gap a lender's surveyor checks before your mortgage goes through
• A heads-up when public records show the home was extended or renovated since it last sold, so a bold price reads as work done, not a seller chancing it
Nestfair is built for buyers. Most valuation tools are really for sellers, and they lean cheerful. This one just tells you what the evidence backs and where the risk sits.
It runs only on for-sale listing pages, and only when you click. No background tracking. No ads.
