A down valuation can seriously disrupt plans to purchase or sell a home, often resulting in renegotiation and, in some cases, the transaction collapsing. We examine why down valuations happen, the effect they can have on both buyers and sellers, and the steps you can take to reduce the risk of this happening or deal with it effectively if it does.
What is a down valuation?
A down valuation happens when a lender’s valuation of the property you intend to purchase comes in below the agreed asking price. Having a Mortgage Decision in Principle before you start your property search can help prevent you from offering more than you are likely to borrow. Even so, it is not always possible to predict whether a surveyor will value the property at the same figure as the seller or estate agent.
In many cases, a down valuation is only identified 4–6 weeks after an offer has been accepted. When the mortgage valuation is lower than the agreed purchase price, it can affect your finance because lenders will usually reduce the amount they are prepared to lend based on their assessment of the property’s value.
Why down valuations happen
There are several reasons why a down valuation may happen:
High asking price – If the seller has set the sale price too high, particularly when they are selling without an estate agent, the valuation is unlikely to support that figure.
Issues identified in the survey – Problems relating to the property’s structure, condition, or age can reduce its value. Issues such as Japanese knotweed, damp, or faulty electrics may lead to extra costs for the buyer, which can affect the valuation unless the seller resolves them before marketing the property.
AVMs (Automated Valuation Models) – Some lenders depend heavily on AI-supported valuations or AVMs. In certain cases, these models may fail to reflect more subjective factors that need human judgement, such as a high-spec interior finish or a sharp rise in local demand.
EPC requirements – Under the RICS Red Book 2025 standards, surveyors are now required to consider EPC (Energy Performance Certificate) ratings and any related risks, which may contribute to a down valuation.
Cautious lenders – Changes in the local or national property market, along with wider economic uncertainty, may lead some lenders to value properties more conservatively in order to reduce potential risk.
Limited comparable sales – A lack of recent property sales in the area, or lower sale prices for similar homes, can also have a negative effect on the valuation.
How are properties valued?
A property is usually valued either through an in-person inspection by a qualified surveyor or by a desktop valuation using an AVM model based on recent local property market data. Both methods will take into account comparable sales, the property’s construction, and any lender concerns where relevant.
If you choose a full survey instead of a basic mortgage valuation, it may reveal issues that are not always obvious during a standard property viewing. Although this can increase the likelihood of a down valuation, a more detailed assessment can also help ensure you are making a sound investment. To understand the difference between a mortgage valuation and a full survey, see our comparison article.
A down valuation is not always entirely negative for a buyer, as it may create an opportunity to renegotiate the purchase price to reflect the cost of any repairs identified during the process.

What to do when your mortgage valuation is lower than your offer
There are several options to think about if your mortgage lender lowers the amount they are prepared to lend:
Renegotiate the sale price – Share the mortgage valuation with the seller and ask to revise the agreed price. If a lower price can be agreed that meets the lender’s valuation, the sale may still be able to proceed.
Challenge the valuation – Although buyers may be less inclined to pursue this route, a seller who believes the property is worth more may be able to provide evidence to support the higher figure. If a revised valuation is accepted, the lender may reconsider and reinstate the original mortgage loan.
Consider alternative mortgage lenders – If your current lender has withdrawn completely, or will not accept a renegotiated purchase price or revised valuation, this does not necessarily mean every lender will take the same view. A specialist lender may apply more flexible criteria, so it can be worth speaking to a broker such as ourselves in these circumstances.
The loan-to-value impact
When a surveyor’s valuation is lower than the agreed sale price and the lender reduces the mortgage loan accordingly, it can reduce the buyer’s equity and may place them in a higher loan-to-value bracket unless they are able to increase their deposit to make up the shortfall.
A higher LTV bracket can reduce the number of mortgage lenders available and may also result in higher mortgage interest rates for the buyer.
For Example: If you secured a 3.6% rate at 80% LTV, but a down valuation pushes your requirement to 85% LTV, your interest rate could jump significantly, adding hundreds to your annual costs.
How sellers can be impacted
Estate agents and surveyors both contribute to property valuations, albeit with some differences in their approaches.
Estate agents and surveyors both play an important part in property valuation, but they assess value from different perspectives and for different purposes. Which valuation carries more weight will usually depend on the context and the reason the property is being valued.
In most cases, a surveyor’s valuation is seen as more accurate and dependable because it is based on an impartial assessment and a more detailed review of the property. This is why surveyor valuations are commonly relied on for legal matters, mortgage lending, and investment decisions. Estate agent valuations can still be useful, particularly for sellers who want an indication of likely market interest and a realistic asking price, but they are generally less formal.
Estate agent valuations
Estate agents focus on the sale and marketing of property. Their valuations are based on current market conditions, recent sale prices, and their knowledge of the local area. These valuations are usually provided free of charge and can help sellers decide on an appropriate asking price. However, estate agents may have a commercial interest in winning instructions, which means some valuations may be more optimistic than the market supports.
They will usually take the following into account:
Comparable properties – Estate agents often review recently sold homes nearby to compare sale prices and estimate the value of the property being marketed.
Location – A property’s location can have a major effect on value. Access to amenities, schools, transport links, and desirable neighbourhoods can all influence the price.
Property condition – The overall state of the home, including any improvements or renovations, will usually affect the valuation. A well-presented and well-maintained property may achieve a stronger figure.
Market trends – Estate agents consider wider market conditions, including supply and demand, interest rates, and the general economic climate.
Size and layout – The number of bedrooms, bathrooms, reception rooms, and the overall amount of space can all influence the value.
Unique features – Features such as a garden, attractive views, or premium finishes may add to the property’s appeal and value.
Local amenities – Nearby parks, shops, restaurants, and leisure facilities can also contribute to how a property is valued.
It is also worth remembering that estate agent valuations can differ, which is why speaking to more than one agent can give a clearer picture of the property’s likely market value.
Surveyor valuations
Chartered surveyors are qualified professionals who assess both the condition and value of a property. Their reports are independent, detailed, and commonly required for mortgage purposes or where a more precise valuation is needed. Surveyors consider factors such as the property’s condition, build quality, possible defects, and the local market. Because of their objective approach and professional standards, their valuations usually carry more weight when finance or major property decisions are involved.
Surveyor valuations are usually carried out on behalf of mortgage lenders and must follow standards set by the Royal Institution of Chartered Surveyors (RICS). A surveyor valuation may include:
Detailed property inspection – The surveyor will usually inspect the property inside and out to assess its condition, structure, and overall quality.
Market value assessment – The surveyor will calculate the property’s market value using factors such as location, size, condition, and comparable local sales. This helps lenders decide how much they are willing to lend.
Property description – The report will normally include key details about the property, such as its size, layout, room numbers, and any notable features.
Defects and repairs – The surveyor may highlight defects, damage, or repair issues, including concerns such as damp, leaks, or structural movement.
Valuation report – Their findings are presented in a formal report setting out the property’s condition, market value, and in some cases any recommended repairs or improvements.
Comparable analysis – Surveyors compare the property with similar homes in the area to support a fair and consistent valuation.
Compliance with RICS standards – Surveyor valuations must follow RICS requirements, helping to ensure the process is professional, consistent, and reliable for lenders.
Professional expertise – These valuations are carried out by trained and experienced professionals with specialist knowledge of valuation methods, construction, and property standards.
Additional advice – In some cases, the surveyor may also provide further guidance on maintenance, improvements, or issues that could affect the property’s value.
This is a general overview of what a surveyor valuation may cover. The exact detail can vary depending on the surveyor involved and the requirements of the mortgage lender.
Frequently Asked Questions
Unfortunately, mortgage down valuations are fairly common, with reports indicating that around 15 per cent of remortgages are affected. They can be especially common with new build properties, where the premium paid often falls away as soon as the property is occupied.
