A mortgage down valuation happens when a lender values a property below the agreed purchase price.
The difference can affect the mortgage amount, deposit and loan-to-value ratio.
It may also require the buyer and seller to reconsider the price.
A home can carry emotional value for a buyer. However, a lender must assess it as security for a loan.
That distinction sits at the centre of every down valuation.
At a Glance
- A down valuation means the lender’s figure is below the agreed purchase price.
- The lender usually calculates borrowing against its own valuation.
- Buyers may need a larger deposit or a lower purchase price.
- Some lenders permit valuation appeals when strong evidence exists.
- Changing lender does not guarantee a higher valuation.
- A down valuation does not always mean the property is unsuitable.
What Does a Down Valuation Mean?
The term describes a difference between the agreed price and the lender’s valuation.
Suppose a buyer agrees to pay £300,000.
The lender then values the property at £280,000.
The £20,000 difference is not automatically added to the mortgage. The lender usually bases its lending decision on £280,000.
RICS notes that “down valuation” is not a formal technical term. It describes a valuation below the agreed transaction price.

Why Do Mortgage Down Valuations Happen?
A down valuation can arise for several reasons.
Limited comparable sales
A valuer normally considers recent sales of comparable local properties.
There may be limited evidence supporting the agreed price.
This issue can affect unusual homes or areas with fewer transactions.
The agreed price exceeds market evidence
Buyers sometimes compete strongly for a property.
The final offer may reflect personal demand rather than wider market evidence.
A lender must still consider what the property could reasonably sell for.
Property condition
Visible defects can affect marketability and value.
Examples may include:
- Structural movement.
- Significant damp.
- Roof defects.
- Incomplete building work.
- Unsafe alterations.
- Evidence of subsidence.
- Poor property maintenance.
The lender could also request specialist reports before making its final decision.
Non-standard construction
Unusual construction can reduce the number of suitable lenders.
It can also make comparable evidence more difficult to establish.
Incorrect property information
The application or sales particulars may contain inaccurate details.
Errors can concern floor area, bedroom numbers, tenure, land or completed improvements.
How Does a Down Valuation Affect the Mortgage?
The lender usually calculates the loan-to-value against its valuation.
Loan-to-value measures the mortgage as a percentage of the property value.
For example:
| Detail | Original position | Lender’s position |
|---|---|---|
| Agreed price | £300,000 | £300,000 |
| Assessed value | £300,000 | £280,000 |
| Requested mortgage | £270,000 | £270,000 |
| Calculated LTV | 90% | 96.4% |
A £270,000 mortgage would represent more than 96% of the lender’s valuation.
The original 90% mortgage product may therefore become unavailable.
The lender could:
- Reduce the mortgage amount.
- Move the case into another LTV band.
- Request a larger deposit.
- Change the product terms.
- Decline the property.
- Request further reports.

What Can You Do After a Down Valuation?
Several routes may be available.
Renegotiate the purchase price
The valuation can provide evidence for a new discussion with the seller.
The seller is not required to accept a lower amount.
However, another mortgage buyer could face the same issue.
Increase the deposit
A buyer may cover the difference using additional funds.
This approach increases the amount committed to the purchase.
The buyer should consider whether paying above the assessed value remains appropriate.
Choose a lower mortgage amount
Reducing borrowing may keep the application within the lender’s accepted LTV band.
This still requires the buyer to fund the remaining difference.
Appeal the valuation
Some lenders have a formal appeal process.
The evidence may need to include:
- Recent completed sales.
- Similar property types.
- Comparable location and condition.
- Accurate floor areas.
- Details of overlooked improvements.
- Evidence of factual errors.
Properties currently advertised do not prove completed market value.
The strongest evidence usually comes from recent completed transactions.
Apply to another lender
Another lender might use a different valuation firm or method.
However, another application creates no guarantee of a different result.
It can also involve further fees, checks and delays.
Speak with a mortgage adviser before submitting another application.
Can an Estate Agent’s Valuation Be Used?
An estate agent’s estimate may support a discussion. However, it does not bind the mortgage lender.
Estate agents and mortgage valuers perform different roles.
An asking price can reflect marketing strategy and seller expectations.
The lender’s valuer considers whether the property provides suitable mortgage security.
Should You Pay More Than the Lender’s Valuation?
That remains the buyer’s decision.
However, the buyer should understand the financial consequences.
Paying above the lender’s figure could mean:
- Contributing more personal capital.
- Beginning with less usable equity.
- Facing a higher effective loan-to-value.
- Taking longer to recover the price difference.
- Having fewer mortgage product choices.
A separate survey may also reveal repair costs not covered by the lender’s valuation.
Read our guide explaining which property survey you may need.
How Can a Mortgage Adviser Help?
A mortgage adviser cannot instruct a valuer to increase the figure.
However, they can explain the effect on the proposed mortgage.
They may help you:
- Recalculate the LTV.
- Review the revised deposit.
- Check the lender’s appeal policy.
- Assess whether the evidence appears suitable.
- Compare alternative lender criteria.
- Consider a different mortgage product.
- Review the risks before another application.
A clear decision starts with accurate numbers.
The valuation may challenge the agreed price. It can also prevent a larger financial problem later.

A down valuation changes the financial structure of a purchase.
It should be reviewed before more money or time is committed.

FAQs About Mortgage Down Valuations
Does a down valuation mean the mortgage is declined?
Not always. The lender may reduce the mortgage or request a larger deposit.
Can I challenge a down valuation?
Possibly. The lender may require recent completed sales and evidence of factual errors.
Will another lender value the property differently?
It is possible, but there is no guarantee. Another lender may reach the same figure.
Does the seller have to reduce the price?
No. The buyer and seller must agree any revised purchase price.
Can a new-build property be down valued?
Yes. Incentives, local evidence and comparable sales can affect the valuation.
Is a down valuation the same as a failed survey?
No. A lender’s valuation and a buyer’s property survey serve different purposes.
Your home may be repossessed if you do not keep up repayments on your mortgage.
