How to Tell If a House Is Overpriced — 7 Checks Using Land Registry Data
Last updated:
Data: HM Land Registry Price Paid Data, UK House Price Index — Open Government Licence v3.0.
Quick answer
A house is overpriced when its asking price sits above what comparable homes nearby actually sold for. You can check this yourself in about 20 minutes with free HM Land Registry data — here are the 7 checks buyers' agents run, and the tool that runs them in seconds.
1. Pull the street's sold prices
Start with what homes on the street actually sold for — the completed figures HM Land Registry records, free, going back to 1995. Search the street on our sold prices in my street page. If recent comparable homes sold for £280,000–£300,000 and this one is asking £340,000, that gap is your first signal.
2. Compare £ per square metre using the EPC floor area
Raw prices ignore size. Divide each comparable sale by its floor area (published on its Energy Performance Certificate) to get £/sqm, then do the same for the asking price. If nearby homes achieved £3,100/sqm and this asking price implies £3,900/sqm, the house is priced above the street's evidence — regardless of the headline figure.
Checking a specific house?
Enter the address and the asking price — we run the sold-price comparison against HM Land Registry data and show you whether the price sits above, within, or below the local evidence, with the reasoning shown. Free, no signup.

A price that looked high a year ago can be fair in a rising market, and vice versa. Check the area's recent direction on the sold prices hub and its outcode page, which show the UK House Price Index trend for the district. Read the asking price against the trend, not against a single old sale.
4. Look at time on market and relistings
A home that has sat unsold for months, or been withdrawn and relisted at the same price, is telling you the market has already judged it overpriced. A recent price reduction is the seller conceding the same point. Neither is proof on its own — but both are signals to weigh against the comps.
5. Compare against the portals' estimate range — knowing its limits
Zoopla and Rightmove publish automated estimates, but they are ranges built from an algorithm, not valuations. Zoopla itself concedes its model “can't consider aspects like a property's condition, features and improvements” (as of 2026-07-04). Use the estimate as one data point among several, never as the answer.
6. Price it against identical house types on the street
Compare like with like: a three-bed semi against other three-bed semis, not against the detached house two doors down. The tighter your comparable set — same type, same street, recent sales — the more confident the read on whether this asking price is out of line.
7. Ask what the price is quietly asking you to ignore
A number can look fair and still be a bad buy. If the home sits in a flood zone, over old coal workings, in a high-radon area, or carries a poor EPC, the “right” price for a problem-free house is the wrong price for this one. This is where a full property check earns its keep — it puts the price next to the risks.
Two honest caveats
Overpriced against the evidence isn't the same as won't sell — in a competitive market, homes go over the comps and still find a buyer, so “the data says it's high” is a negotiating position, not a guarantee it will drop. And the reverse: a fair price on a house with a flood or subsidence problem is still a bad buy. Price is one axis; risk is the other.

What this method cannot tell you
Sold-price comparison can't see a property's condition, recent renovations, lease terms, or how much chain pressure the seller is under — that's survey and solicitor territory. It tells you what the evidence says about the price, not everything that decides whether to buy.
