The Reality of Falling Valuations in 2025

In 2025, the UK property market presents a mixed picture. While certain areas are seeing renewed buyer activity, others have slowed, and surveyor valuations often reflect a cautious view of market conditions. For buyers, homeowners, and investors, this can mean one of the most frustrating outcomes in the mortgage process — a valuation that comes in lower than the agreed purchase price or expected property value.

A down-valuation can affect a variety of transactions: residential purchases, buy-to-let acquisitions, remortgages, portfolio refinances, and even development finance. In every scenario, it impacts the loan-to-value (LTV) ratio, which in turn can limit borrowing, increase interest rates, or derail the deal altogether.

Understanding why valuations fall and how to respond is essential if you want to keep your plans on track without overpaying or compromising on finance terms.

Why Valuations Fall

Valuations can be reduced for many reasons. Surveyors may be factoring in recent sales data showing a drop in prices locally, particularly in areas where demand has slowed. They might also take a more cautious stance if a property type has limited market appeal — for example, unusual construction, short leases, or location above commercial premises.

For investors and developers, lender-appointed valuers will also look closely at the commercial viability of the property. If projected rental yields or resale values seem optimistic compared to the market, the valuation will be adjusted accordingly.

In some cases, the issue isn’t the property itself but the wider market climate. When interest rates are higher, surveyors may anticipate a smaller pool of buyers willing to pay the asking price in the future, which reduces the property’s market value in their report.

For a deeper look at how lenders interpret these reports, our blog on how mortgage underwriting has changed in 2025 explains why valuations are more tightly scrutinised now than in previous years.

Impact on Homeowners and Buyers

When a residential buyer faces a down-valuation, the lender will usually recalculate the loan amount based on the lower figure. This can mean having to find a bigger deposit or accepting a higher rate to proceed. For remortgaging homeowners, it may mean losing access to the most competitive rates because the LTV has increased.

If you are buying a property using a government scheme such as shared ownership or the First Homes Scheme, a down-valuation can also create problems with eligibility or the percentage you’re allowed to purchase. Similarly, buyers relying on developer offers and incentives may find that these perks are stripped out of the valuation, raising their LTV and changing their mortgage terms.

Impact on Investors and Developers

For investors purchasing buy-to-let properties, down-valuations affect both the LTV and the rental stress test. If the rent is not high enough to meet the lender’s required interest coverage ratio (ICR) based on the new valuation, the borrowing amount will be cut.

In development finance, a lower-than-expected Gross Development Value (GDV) can reduce the loan available for the project, forcing you to inject more equity or adjust the scope of the build. Our blog on LTV, LTC, and GDV covers exactly how these figures interact in lender calculations.

For portfolio landlords, a down-valuation on a single property can impact the overall gearing across the portfolio, particularly if you’re refinancing multiple units together. This can have knock-on effects on interest rates across all the loans.

Mortgage Options When Facing a Down-Valuation

The options available will depend on your specific circumstances, but in most cases, you will be looking at one of the following approaches:

Renegotiate the Purchase Price: If you are buying, the most direct solution is to go back to the seller and renegotiate based on the lender’s valuation. This is particularly viable in a buyer’s market.

Increase the Deposit or Equity Contribution: Adding more personal funds can bring the LTV back in line with your original mortgage product, avoiding a higher interest rate.

Explore Alternative Lenders: Different lenders have different panel surveyors and valuation methodologies. Switching to another lender may result in a more favourable valuation, especially if they use a surveyor with stronger knowledge of the local market.

Use Specialist or Bridging Finance: For investors and developers, short-term finance such as bridging loans can provide the funds needed to complete the purchase or project while you work to increase the property’s value.

Review the Timing of the Application: In some cases, waiting and reapplying in a few months — perhaps after completing improvements to the property — can result in a higher valuation.
