A house is overpriced when the asking price runs ahead of what comparable homes have actually sold for. You can check this yourself in minutes: compare sold prices (not other asking prices), work out £ per square foot, read the listing's price history, and look at how long it's been on the market. Here are the seven checks.
A house is overpriced when the asking price runs ahead of what comparable homes have actually sold for. The asking price is the seller's opening position, set with the help of an agent who wants the instruction — it is not a measure of value. You can test it yourself in minutes by looking at evidence the agent would rather you didn't dwell on: recent sold prices, price per square foot, the listing's own price history, and how long it has been sitting unsold. The seven checks below turn a gut feeling into a defensible view.
Asking price is not value
Estate agents win instructions partly by suggesting an attractive figure to the seller, so asking prices tend to start optimistic and drift down. Comparing one listing to other listings just compounds the optimism — you end up benchmarking hope against hope. The only honest reference point is the price homes have completed at. Everything that follows anchors to achieved prices, not advertised ones. That is the whole difference between negotiating from emotion and negotiating from evidence.
The 7 checks
1. Recent sold comparables
Find three or four homes of similar size, type and condition that sold nearby in roughly the last six to twelve months. Use HM Land Registry Price Paid data or a portal's sold-price tool. The closer the comparable — same street, same number of bedrooms, similar plot — the more weight it carries. If every genuine comparable sold for noticeably less than this asking price, you have your answer.
2. Price per square foot
Dividing price by internal floor area gives you a like-for-like number that strips out size differences. Work out the £/sqft on your comparable sales, then apply that range to this property's floor area. If the asking price implies a £/sqft well above what the street has achieved, the gap is the overpricing. Floor area is usually in the listing or the EPC; if it isn't, ask the agent.
3. Price history and reductions
Portals show a listing's price history. A property that has already been reduced once or twice is openly admitting the first price was wrong — and signalling there may be more room. A previous failed sale (listed, withdrawn, relisted) tells the same story. A clean history at a high price, by contrast, means the price is untested.
4. Days on the market
How long a home has been listed is one of the cleanest pricing signals there is. A property that has sat well past the local average is usually overpriced for the demand it faces. We cover how to read this properly — including the relisting trick agents use to hide it — in our guide to days on the market.
5. Over-improvement for the street
A street has a ceiling. A home finished to a far higher standard than its neighbours rarely recovers the full cost of that work, because buyers price the location as much as the kitchen. If the asking price relies on the seller's renovation spend rather than what the street supports, you are being asked to pay for their taste. Lovely extras are a reason to buy, not always a reason to pay more.
6. EPC and works needed
Read the EPC and look honestly at condition. A poor energy rating, an old boiler, single glazing, or a roof near the end of its life all carry real costs you will inherit. A price that ignores obvious works is, in effect, asking you to fund them twice — once in the purchase and again in the repairs. Quantify the likely spend and treat it as a deduction from fair value.
7. Valuation versus mortgage-survey risk
If your evidence says a home is overpriced, the lender's surveyor may agree. A down-valuation means the lender will only lend against the lower figure, leaving you to renegotiate or cover the difference in cash. Spotting the over-pricing before you offer protects you from agreeing a number the mortgage simply won't support.

Worked example: this home versus three comparables
Put the checks together. Take the asking price, the floor area, and three genuine sold comparables, and reduce everything to £/sqft. The illustrative figures below show how a confident-looking asking price can sit well above what the street has actually paid — here, around £475/sqft asked against a comparable range of roughly £400–£420/sqft.
| Property | Price | Floor area | £/sqft |
|---|---|---|---|
| This home (asking) | £475,000 | 1,000 sqft | £475 |
| Comparable A (sold) | £408,000 | 1,020 sqft | £400 |
| Comparable B (sold) | £420,000 | 1,000 sqft | £420 |
| Comparable C (sold) | £399,000 | 950 sqft | £420 |
On those numbers, fair value for a 1,000 sqft home lands around £400,000–£420,000, not £475,000. That roughly £55,000–£75,000 gap is not a figure to be shy about — it is the basis for a calm, evidence-led offer. Figures here are illustrative; the method is what matters.
Why down-valuations matter to you
A down-valuation is the market checking the agent's optimism. If you agree an overpriced figure and the lender's surveyor values lower, you are left renegotiating after you have already emotionally committed — the worst position to bargain from. Doing the seven checks first means you offer at a number the survey is likely to support, so the deal holds together rather than wobbling at the mortgage stage.
Turning the checks into an offer
Establishing that a home is overpriced is only useful if it shapes your offer. Once you have a fair-value range, pair it with the listing's days on the market and decide how much to offer and how far below asking the evidence lets you go. The estate agent speaks in superlatives; you reply in comparables.
Broc does this groundwork for you. It pulls the sold comparables, works out the £/sqft, reads the price history and time on the market, and gives you a defensible valuation range for a specific address — the same checks above, gathered in one place. Run a free valuation on the home you're weighing up and offer from evidence, not from the asking price.

Frequently asked questions
How do I know if a house is overpriced?
Compare it to recent sold prices of similar nearby homes on a £/sqft basis — not to other asking prices. Asking prices reflect what sellers hope to get; sold prices reflect what buyers actually paid. If the asking price sits well above the sold £/sqft for comparable homes on the same street, the listing is likely overpriced.
Where can I see what houses actually sold for?
HM Land Registry Price Paid data records every completed sale in England and Wales, and the major property portals publish sold-price tools drawn from the same source. Both show achieved prices rather than asking prices, so they are the right reference point for judging value.
What is a down-valuation?
A down-valuation is when a mortgage lender's surveyor values the home below the price you have agreed. The lender then bases your loan on the lower figure, which can force a renegotiation or leave you to find the shortfall in cash. It is one of the clearest external signals that a price was too high.
Does a long time on the market mean a house is overpriced?
Often, yes. A home that has sat unsold well beyond the local average is usually telling you the price is ahead of demand. Condition or a difficult layout can also be the cause, but in most cases a stale listing points to pricing — and gives you room to offer below asking with evidence.
