Imagine you’ve finally had an offer accepted on your dream home, only for the bank’s surveyor to say the property is worth less than you agreed to pay.
This is known as a down valuation and has become surprisingly common in the UK recently (about 1 in 5 mortgage cases in early 2025 faced this issue), so it’s important for homebuyers to know how to respond.
In this guide, we explain what mortgage valuations are, why down valuations happen, and step-by-step what to do if it happens to you.

What Is a Mortgage Valuation?
A mortgage valuation is a brief assessment of the property’s value that your lender arranges when you apply for a mortgage.
It’s essentially for the lender’s benefit as they want to be sure the home is worth the amount they’re lending, as security for the loan.
Unlike a full structural survey that you might commission for yourself, a mortgage valuation isn’t very detailed. In fact, it might be done in a few minutes, sometimes via an automated model or a quick drive-by, and you may not even get to see the report.
The lender’s valuer will look at recent sale prices of similar homes and the property’s general condition or features to estimate its market value.
If the valuation comes back at or above the price you’ve offered, that’s great; it means the lender is satisfied the property is sufficient security for the mortgage.
You’ll likely proceed to get your mortgage offer approved. However, if the valuation is lower than the purchase price, the trouble starts. This is what’s known as a down valuation.
What Is a Down Valuation?
A down valuation happens when the lender’s surveyor values the property at less than the price you’ve agreed to pay.
In other words, the bank thinks the home isn’t worth what you offered. When a buyer applies for a mortgage, the lender sends a valuer to check the property’s worth; if they deem it lower than the agreed sale price, the result is a down valuation.
Crucially, the lender will only lend based on this lower valuation figure, not the higher offer amount. That means they may not provide the full loan to cover the agreed price, leaving a shortfall that you or the seller have to address.
Why Do Down Valuations Occur?
In most cases, down valuations occur because estate agents or sellers were overly optimistic in pricing the home, setting an asking price above what recent sales can support.
In a cooling market, prices may be slipping, and surveyors are cautious since they work for the lender and want to avoid overvaluing a property.
Lenders themselves may encourage caution as a safeguard in uncertain market conditions (for example, when interest rates are high or prices are volatile).
Essentially, if there’s a gap between what buyers are willing to pay and what hard data says the home is worth, a down valuation can happen.
As professional mortgage advisors, we’ve seen cases of surveyors valuing homes 10-15% below the agreed price when the market is in decline.
Even in stable times, a down valuation can occur if the property has issues (like structural problems) or simply lacks comparable sales to justify the price.
How Common Are Down Valuations?
Down valuations tend to spike when the market is turning. Right now (July 2025), they are arguably quite common.
One mortgage network reported that in early 2025, roughly 20% of transactions (including purchases and remortgages) were coming back with down-valued surveys.
Another analysis in 2024 found that across Britain, down-valued properties were typically being marked down about 2.8% from the agreed price.
This means thousands of buyers are facing this issue, so if it happens to you, you’re certainly not alone.
The good news is that there are concrete steps you can take to handle a down valuation and still move forward with your home purchase. Let’s discuss those.
What to Do if a Mortgage Valuation Is Lower Than the Offer?
A low valuation doesn’t have to be the end of your homebuying journey. You have several potential options to resolve a down valuation.
Here are practical steps to take if the mortgage valuation comes in below your agreed offer price:
Renegotiate the Price With the Seller
Generally, this should be your first move. Share the valuation report with the seller and ask if they’re willing to reduce the price to the surveyed value.
After all, if your lender’s surveyor said the property is worth less, any new buyer’s lender might do the same.
Sellers often realise that holding out for the higher price could be futile (unless a cash buyer comes along who doesn’t need a mortgage).
Many sellers, to keep the sale from collapsing, will agree to meet you somewhere closer to the valuation figure so that the deal can proceed.
It might feel awkward, but remember: a down valuation is a reality check for everyone involved.
Challenge or Appeal the Valuation (If You Have Evidence)
In some cases, you can dispute a down valuation, but you’ll need solid proof that the property is worth more.
This means gathering comparables: for example, recent sale prices of similar properties in the area that support your original offer price.
Typically, a lender might consider an appeal if you can provide three comparable sales that closed at the higher price point.
Also, if the surveyor down-valued due to certain repair issues (e.g., they thought the roof needs expensive work), and you have quotes or reports showing those costs aren’t as high as assumed, that can be part of your challenge.
Explore Other Mortgage Options
Sometimes you might solve the issue by adjusting your financing rather than the price. For instance, could you switch to a mortgage product with a higher loan-to-value (LTV) ratio?
If your current lender only offers (say) an 80% mortgage but values the home low, you end up short. But if you qualify for a 90% or 95% mortgage elsewhere, you might borrow more and cover the gap.
Let’s understand it with a simple example:
Suppose you agreed to £300,000, but the bank valued it at £250,000. With an 80% loan, the bank would lend only £200,000 (80% of £250k), leaving you £40k short of the £240k you expected.
If you found a 95% mortgage, a new lender might lend about £237,500 on that £250k value, closing most of the shortfall.
However, keep in mind that high-LTV mortgages usually come with higher interest rates or stricter criteria, so this is not always an easy solution.
We recommend speaking to a mortgage advisor about what products are available. The key point is that a low valuation might force you to either put down a larger deposit or pay a slightly higher rate to make the numbers work.
Try a Different Lender or Surveyor
Mortgage valuations are opinions, not an exact science, and another lender’s valuer might see things differently.
If time permits, you can apply for a mortgage with a different bank and hope their valuation comes in higher.
There’s no guarantee this will work (banks often use similar data, and occasionally even the same surveying firms), but there are cases where a second valuation is more generous.
We’ve seen buyers switch lenders and get a valuation at the full offer price on the next try. This route can be time-consuming; you’ll need to go through another application, so weigh it up carefully.
It’s most useful if your first lender seems unusually harsh or if you suspect their surveyor lacked local knowledge.
Again, a mortgage advisor can advise if certain lenders tend to be more lenient for that property type or area.
Increase Your Deposit to Cover the Shortfall
If you’re in love with the house and can afford it, you might choose to put in more of your own money. Essentially, you make up the difference between the valuation and the offer.
Using savings or family help to beef up your deposit can fill the gap so that the mortgage covers the remainder.
For example, if the lender will only finance up to £200k because of a downvaluation on that house but the price is £250k, you’d need to supply the other £50k yourself (instead of say another amount you may have planned initially).
This is obviously not feasible for everyone, but it’s a straightforward fix if you have the funds. Be mindful of gifted deposits or loans from relatives; these need to be declared to your lender and might require additional paperwork.
Walk Away as a Last Resort
If all else fails, that is, the seller won’t budge, you can’t secure a larger loan or extra cash, you might have to consider pulling out of the purchase.
This is never ideal after investing time and money in surveys, solicitors, etc., but sometimes it’s the only sensible option.
A down valuation is a signal that you might be overpaying for that home. If neither you nor the seller can bridge the valuation gap, proceeding at the original price could mean you’re immediately in negative equity (owing more on the mortgage than the home is worth).
As painful as it is, walking away could save you from bigger financial trouble down the line.
Frequently Asked Questions
Can I challenge a down valuation?
Yes, you can appeal a down valuation, but you’ll need evidence. Ask the lender if they’ll reconsider, and be prepared to provide recent comparable sales data that support the higher price.
What if the seller won’t reduce the price after a down valuation?
If the seller refuses to budge, you have a few choices. You could try another lender’s valuation in hopes of a better result, or see if you can increase your deposit to cover the shortfall. If neither is possible, you may have to walk away from the deal.
How can I avoid a down valuation?
To reduce the risk, do your homework on prices and be cautious about overpaying. Before making an offer, look at recently sold prices for similar homes in the area. If you offer far above what comparable homes fetched, you’re more likely to be down-valued.
Will a down valuation ruin my mortgage offer?
Not necessarily, but it will change the terms. A down valuation means the lender is only willing to lend against the lower appraised value, so your mortgage offer amount may be reduced.
Your home may be repossessed if you do not keep up repayments on your mortgage.
