Down valuation: what to do if a house is valued lower than your offer
If a house is valued lower than your offer, your lender will lend on the lower figure, not the price you agreed. So the gap has to be covered by you, renegotiated with the seller, or challenged. A down valuation is common and usually fixable. Here's what it means, how to work out the shortfall and what your options are.
First published September 2024. Fully updated September 2026 with a worked example, remortgage and new-build guidance and a step-by-step guide to challenging a valuation.
What the lender does
Lends on the lower
Your loan-to-value is worked out on the valuation or the price, whichever is lower.
Who pays the gap
Usually you
Unless the seller agrees to drop the price, the shortfall comes out of your deposit.
Challenging it
Possible, not easy
Lenders will look at sold-price evidence through your broker, but most valuations stand.
Your best move
Don't panic
Get the figures, talk to your broker, then decide whether to renegotiate, top up or walk away.
What is a down valuation?
Before a lender agrees your mortgage, it sends a surveyor (or uses a computer model) to value the property. This is the lender's valuation. It protects the lender, not you, and it isn't a survey of the property's condition.
A down valuation is when that figure comes in below the price you've agreed to pay. The mortgage offer is then based on the lower value, which can leave a gap in your funding.
What happens if a house is undervalued: a worked example
Say you've offered £300,000 with a 10% deposit, so you need a 90% loan-to-value (LTV) mortgage. The lender's surveyor values the property at £280,000.
| Before valuation | After £280,000 down valuation | |
|---|---|---|
| Price you agreed | £300,000 | £300,000 |
| Value the lender uses | £300,000 | £280,000 |
| Maximum loan at 90% LTV | £270,000 | £252,000 |
| Deposit needed | £30,000 | £48,000 |
| Extra cash to find | None | £18,000 |
Illustrative figures only. They ignore fees and other buying costs, and assume the lender will still lend at 90% LTV and that you pass its affordability checks.
The £20,000 valuation gap turns into £18,000 of extra cash, because the lender still covers 90% of the lower value. It can also work out differently:
- Seller drops to £280,000: the loan is £252,000 and your deposit falls to £28,000.
- You meet in the middle at £290,000: the loan is still £252,000, so your deposit is £38,000.
- You move to a 95% LTV mortgage: 95% of £280,000 is £266,000, so your deposit is £34,000, but the rate is likely to be higher.

Your options when a property is valued below your offer
1. Renegotiate with the seller
Often the first step
Share the valuation figure with the estate agent and ask for a reduction. The next buyer's lender may well reach a similar number, so sellers often agree to drop or split the difference.
2. Cover the shortfall
If you have the savings
Put in more deposit to bridge the gap. A family gift can help, but check the lender accepts it. Only do this if you're comfortable paying more than the lender thinks it's worth.
3. Challenge the valuation
Needs solid evidence
Your broker can send the lender recent sold prices for similar nearby homes and ask for a review. It works best when the valuer has made a clear mistake.
4. Try another lender
A second valuation
A different lender will instruct its own valuation, which may come in higher. There's no guarantee, it takes time, and some surveyors work for several lenders.
5. Walk away
Before you exchange
Until contracts are exchanged you aren't legally committed. If the numbers no longer work, pulling out can be the right call, though you may lose money already spent on fees and searches.
A down valuation doesn't just affect the deposit. A higher LTV can mean a higher rate, and some lenders also retain part of the loan until repairs are done, or decline the property altogether. Your broker can tell you which applies.
Why do down valuations happen?
Valuers must be able to back up their figure with evidence. The most common reasons a surveyor values a house less than the offer are:
| Reason | What it means |
|---|---|
| Comparable sales | Similar homes nearby have sold for less. Valuers use sold prices, not asking prices. |
| Market changes | When rates rise or the market cools, valuers get more cautious. In a fast-rising market, sold prices can lag behind what buyers are now paying. |
| Bidding wars | Offering over the asking price to win a property can leave you above what the evidence supports. |
| Condition | Damp, subsidence, an old roof or dated wiring can reduce the value or lead to a retention. |
| Non-standard features | Things like spray foam insulation, non-standard construction or a flying freehold can narrow the pool of buyers and lenders. |
| Energy efficiency | A poor EPC rating can make a home less attractive and more costly to run. |
AVM or physical valuation: does it matter?
Many lenders now use an automated valuation model (AVM) for lower-LTV cases, rather than sending a surveyor. An AVM uses sold-price data and property records.
If the AVM can't confirm the price with confidence, the lender will usually book a physical valuation instead. That isn't a down valuation, just a delay. But an AVM can also return a lower figure, especially for unusual homes or areas with few recent sales, and an in-person inspection may give a better result.
New builds and incentives
New builds are a common source of down valuations. The price often includes a "new-build premium" that disappears once the home is lived in, and valuers look past developer marketing to the resale value.
Incentives matter too. Developers must declare cashback, paid legal fees, furniture packs and similar deals on the UK Finance Disclosure of Incentives form. Many lenders cap incentives at around 5% of the price, and some deduct anything above that from the value they lend on.
Down valuations when you remortgage
When you remortgage to a new lender, a lower-than-expected valuation can push you into a higher LTV band, and higher bands usually come with higher rates.
For example, with a £180,000 balance on a home you expected to be worth £250,000, your LTV would be 72% and within a 75% band. If it's valued at £235,000, your LTV becomes about 77%, tipping you into the 80% band. Figures are illustrative.
Your options include trying a lender whose valuation may differ, paying down a lump sum to get back under the band, or taking a rate switch with your current lender, which usually doesn't need a new valuation.
What does a down valuation mean for the seller?
For sellers, a down valuation is a warning sign rather than a verdict. The next buyer's lender may reach a similar figure, and relisting costs time. A seller can refuse to reduce, hold out for a cash buyer or someone with a bigger deposit, or share the difference with the buyer. Price reductions are often agreed to keep the chain moving.
Can I challenge a down valuation?
Yes, but go in with realistic expectations. Lenders rarely change a valuation because a buyer disagrees. They are more likely to review it if the valuer has got the facts wrong or missed strong evidence.
- Get the facts from your brokerFind out the valuation figure and any reasons given, such as condition or lack of comparables.
- Check for factual errorsWrong number of bedrooms, a missed extension, the wrong floor area or the wrong property type are the strongest grounds.
- Gather comparable evidenceUsually around three sold prices for similar homes nearby, from roughly the last six months. Asking prices don't count.
- Your broker submits the appealThe lender passes it to the valuer, who either stands by the figure or revises it. This can take a week or more.
- Plan for either outcomeKeep talking to the seller and line up another lender at the same time, so you don't lose momentum if the figure stands.
Before you pay more than the valuation
- Can you afford the extra deposit and still keep an emergency fund?
- Would you be happy if the property's value stayed at the valuation for several years?
- Could a higher LTV make it harder to remortgage when your deal ends?
- Has the valuation flagged condition issues that need a full survey?
A mortgage valuation isn't a survey. If the valuer mentions condition problems, get your own survey. Our guide to property surveys explains which level suits your home. To see where the valuation fits in the buying process, read the mortgage timeline from application to approval.

Down valuation FAQs
Is a down valuation common?
Yes. They happen most in cooling markets, with new builds and when buyers offer over the asking price. They don't mean anything is wrong with you or your application.
Can the seller see the mortgage valuation?
No. The valuation report belongs to the lender, and you may not see it in full either. You or your broker can tell the agent the figure to support a price renegotiation.
Does a down valuation mean I've overpaid?
Not necessarily. It means the valuer couldn't find enough evidence for your price on that date. But it's worth thinking carefully before paying well above it, especially if you might need to sell or remortgage soon.
Will a different lender give a higher valuation?
It might. Valuations are a professional opinion and can vary. But if the evidence genuinely points to a lower figure, a second valuer is likely to agree.
Can I still get a mortgage if the house is valued lower than the offer?
Usually, yes. The lender will still lend, but on the lower value. You'll need to cover the difference, agree a lower price or find another lender.
How long does it take to challenge a down valuation?
Often one to two weeks, depending on the lender and the valuer. Keep your solicitor and the seller informed so the chain doesn't stall.
