My house is dated. How much less will it sell for?
Published 9 October 2026 · 5 min read · By Evren Ergin
A home that needs modernising typically sells for less than a similar updated home on the same street, and one agency study put the gap at about 4.5% on average. The work itself usually costs far more than that gap, which is why most sellers do better selling as it stands than modernising first.
TL;DR
- •An unmodernised home sold for about 4.5% less than similar modernised homes in the same area, in a Benham & Reeves study published on 25 April 2022.
- •The same study put modernising at about 15.8% of a home's value, several times the discount buyers applied.
- •On those averages the discount was about £16,000 and the work about £56,600, so renovating to capture the gap did not pay.
- •Your street matters more than any average, so ask competing local agents what your home as it stands is worth.

Research on this question is limited. The most-quoted figures come from an estate agency study, now several years old, so this article uses them to show the shape of the trade-off and not as a current price list.
What does an unmodernised home mean?
An unmodernised home is one that has not had a significant update to its kitchen, bathroom, heating, wiring or decoration for many years. Agents often call it dated, tired or in need of modernisation. It is a description of condition and not a defect in the building.
How much less does a dated house sell for?
Benham & Reeves published a study on 25 April 2022 using PropertyData market values for England. It found unmodernised homes were about 4.5% cheaper than comparable modernised homes in the same area.
Dated versus updated: England averages (source: Benham & Reeves, 25 April 2022; gap calculated by ValuQ)
| Measure | Figure |
|---|---|
| Average modernised price | £374,051 |
| Average unmodernised price | £358,034 |
| Price gap (calculated: £374,051 minus £358,034) | £16,017 |
| Average cost to modernise | £56,569 (15.8% of value) |
| Unmodernised price plus work | £414,604 |
| Extra cost versus buying modernised | £40,552 |
The table shows why buyers of dated homes ask for a discount: their total outlay can exceed the price of an updated home. It also shows why you rarely gain by doing the work yourself. If the buyer pays £16,017 less and the work costs £56,569, spending on a full renovation to close the gap loses money on average.
Does the gap differ by area?
Yes, widely. The same study reported that in London unmodernised homes were about £32,000 cheaper but cost about £82,600 more once the work was added, while in the North East the overspend was smallest at about £6,800. Local prices and local building costs both move the result, which is why a national average is only a starting point.
Why might my house sell for more or less than the average?
Three things decide it: how much demand there is for homes like yours, how recently similar homes sold, and how much work buyers think yours needs. Buyers also price in uncertainty. A home with clear builder quotes and a clean survey history looks less risky than one with unknowns.
The market backdrop matters as well. Rightmove reported in August 2026 that new-seller asking prices fell 2% in the month and cut its 2026 forecast to between 0% and a 2% fall. When buyers have more choice, move-in-ready homes tend to draw attention first, so a dated home needs a realistic price from day one.
What should I do if my house is dated?
- Get valuations on the house as it stands before spending on any work.
- Fix what a survey would flag, such as damp, roof and guttering, electrics and pests.
- Refresh with a deep clean, a neutral coat of paint and a tidy garden.
- Get two or three builder quotes for the big jobs you will leave, and keep them to show buyers.
- Price for the buyer who plans to modernise, and be ready for a smaller pool of buyers if the home is hard to mortgage.
The Home Owners Alliance notes, in a guide updated on 8 October 2026, that selling in poor condition means expecting a lower price, and that some homes will only suit cash buyers.
How do I find out what my dated house is worth?
ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents. Competing agents each see the property and send a valuation, you see them all on one screen, and agents never get your details until you choose to connect. If the valuations cluster closely, you have a reliable range for the house as it stands.
Is it better to modernise before selling or sell as it is?
For most sellers, selling as it is. On the Benham & Reeves averages the discount for a dated home was about £16,000 while modernising cost about £56,600. A local agent can say whether your street is an exception.
Will a dated kitchen put buyers off?
It lowers what some will pay and narrows the buyer pool, but many buyers prefer to choose their own kitchen. A deep clean, fresh paint and new handles often help a tired kitchen more than a replacement does.
Should I price a dated house lower from the start?
Price to the evidence, not to the work. Ask agents to value it as it stands and compare their reasoning. A price that matches sold homes of the same condition tends to draw offers; one set as if updated tends to sit.
Can I get a mortgage on a house that needs a lot of work?
Sometimes not. Homes with serious defects can be hard for buyers to mortgage, which can limit you to cash buyers. Builder quotes and a clear survey help lenders and buyers judge the risk.
