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. No signup.

Check This Asking Price

3. Check the outcode trend: is the area rising or falling?

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A home that has sat unsold for months, or been withdrawn and relisted at the same price, is telling you the market has already judged it overpriced.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, because 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.

Ready to make an offer?

The Complete report compiles the evidence you take to the negotiation: comparable sales with £ per square metre, a value range with the reasoning shown, and 15+ checks (flood, coal mining, ground stability, EPC, crime trend and schools) for the exact address. It's the difference between “it feels overpriced” and an offer you can defend.

You can spot an overpriced listing. Can you prove it to the agent?

The method above gets you to a hunch. A defensible offer needs the comparables written down, and a fair price on a house with a flood or subsidence problem is still a bad buy. Enter the address and the £24.99 Complete report puts the recorded sale prices for that street next to 15+ official risk checks, so you negotiate on both axes.

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.

Frequently asked questions

How do I know if a house is overpriced?
A house is overpriced when its asking price sits above what comparable homes nearby actually sold for. Compare the asking price to recent sales on the street (HM Land Registry Price Paid Data) and the £ per square metre they achieved. If the asking price implies a materially higher £/sqm than the comparables, it's above the evidence.
What percentage over sold prices is too much?
There's no fixed percentage: it depends on the area's trend and how dense the comparable sales are. In a fast-rising market a home can sell 10% above last year's comparables and still be fair; in a flat market the same gap is a red flag. Evidence (comps + £/sqm + trend) beats any rule of thumb.
Should I offer below the asking price?
If the sold-price evidence puts the fair value below the asking price, an evidence-led offer below asking is reasonable, and easier to defend when you can show the comparables. This isn't a formula: factor in the area trend, time on market and how much you want the specific home. The point is to anchor your offer to data, not to the brochure.
Do estate agents overprice houses on purpose?
Some valuations are pitched high to win the instruction, so an asking price is a starting position, not an appraisal. That's exactly why you check it against what comparable homes actually sold for rather than taking the listing at face value.
Is a house overpriced if it's been on the market a long time?
A long time on market is a signal, not proof. Check the relisting and price-reduction history and, more importantly, the comparable sales. A home can linger because it's overpriced, or because of a chain collapse or a quiet season. The comps tell you which.
What's a fair offer on a £300,000 asking price?
Work it from £/sqm. If the home is 90 sqm and comparable sales on the street achieved about £3,000/sqm, the evidence points to roughly £270,000, so £300,000 is asking ~11% over the comps. A fair opening offer anchors to that evidence, then adjusts for the area trend and the property's condition.
