A below market value bridging loan is short-term property finance used where a property is being purchased for less than its genuine market value. Depending on the lender and the circumstances of the transaction, the lender may be prepared to calculate its loan-to-value against the property’s assessed market value rather than simply the lower purchase price.
That can make bridging finance particularly useful for investors buying discounted properties where a conventional mortgage would require a larger cash contribution.
However, buying something cheaply does not automatically make it a below market value transaction in a lender’s eyes. The lender will usually want to understand why the discount exists, whether an independent valuation supports the higher value and how the bridging loan will eventually be repaid.
Some lenders are comfortable with genuine BMV transactions, while others will still calculate lending against the lower of the purchase price and valuation. Current lender criteria demonstrate how much approaches can differ. For example, United Trust Bank states that its normal maximum loan is calculated against the lower of purchase price or valuation, but it can consider market-value-based lending on an undervalue purchase where its additional criteria are satisfied.
If you are considering this type of purchase, I Need Advice can help you find a mortgage adviser familiar with bridging finance and unusual property transactions. The adviser can look at the purchase price, proposed valuation, required borrowing and exit strategy before you commit to a particular lender or structure.

What counts as a below market value (BMV) purchase?
A BMV purchase is a transaction where the agreed purchase price is genuinely lower than the property’s current market value.
The distinction between price and value matters.
If a seller originally advertises a property for £300,000 and eventually accepts £250,000, that does not necessarily mean you have bought a property worth £300,000 for £250,000. The original asking price may simply have been too high.
For lending purposes, the stronger question is: what would the property reasonably be expected to sell for in the market?
RICS’ current valuation standards use the term market value, which broadly considers the amount an asset should exchange for between willing parties in an arm’s-length transaction after proper marketing and without compulsion. The current RICS Red Book standards have applied since January 2025.
You may also hear brokers and lenders use the phrase open market value (OMV). RICS has clarified that “open market value” is not itself a defined basis in the current Global Red Book, although the terminology is still widely encountered within property finance.
BMV opportunities can arise in situations such as:
- a seller needing a particularly quick and certain completion;
- an off-market negotiation;
- a probate or estate sale;
- a family or connected-party transaction;
- a property requiring work that restricts the pool of conventional buyers; or
- a time-sensitive investment purchase.
None of these circumstances automatically proves that the property is below market value. An independent valuer and the lender still need to be comfortable with the figures.
The same applies to auction purchases. Winning a property at auction for less than you expected to pay does not automatically establish that it is worth substantially more.
How do below market value bridging loans work?
A bridging loan is normally secured against property for a relatively short period. Instead of assessing the application in exactly the same way as a long-term residential or buy-to-let mortgage, a bridging lender will pay particular attention to the security property, loan-to-value and the borrower’s proposed exit.
With a normal purchase, a lender may calculate its maximum loan using the lower of:
- the price being paid; or
- the lender’s valuation.
A specialist BMV bridging lender may take a different approach where there is convincing evidence that the property has genuinely been purchased at a discount.
In that situation, it may calculate its loan-to-value using the higher independently assessed market value.
That can significantly reduce the cash the buyer needs to put into the purchase.
The important point is that BMV lending is not a standard rule applying to every bridging lender. Each lender has its own policy on valuation, borrower contribution, transaction structure and acceptable discounts.
How lenders value BMV property for bridging finance
The valuation is one of the most important parts of a BMV bridging application because the entire funding structure may depend on the lender accepting a value significantly above the purchase price.
A lender will not normally base its decision simply on what the buyer or seller believes the property is worth.
For secured lending valuations, RICS advises valuers to continue using professional market-value assessments under the Red Book framework.
Depending on the lender and property, the valuation process may consider comparable transactions, location, condition, tenure, demand, marketability and other factors affecting what buyers would realistically pay.
Purchase price versus market value
Suppose you agree to buy a property for £150,000.
You believe it is worth £200,000, and the lender’s appointed valuer also reports a market value of £200,000.
If a lender restricts borrowing to 70% of the £150,000 purchase price, the maximum loan before other considerations would be:
£150,000 × 70% = £105,000
However, if a specialist lender accepts the £200,000 market value for calculating its LTV, the same 70% calculation would give:
£200,000 × 70% = £140,000
That £35,000 difference could materially reduce the amount of cash required to complete.
It is only an illustration. The actual advance can also be affected by arrangement fees, valuation costs, legal fees, retained or rolled-up interest and other lender requirements.
Example of a BMV bridging loan
Consider an investor who agrees to purchase a property from a motivated seller for £180,000.
A lender’s valuation subsequently supports a market value of £240,000.
If the lender is comfortable advancing 70% against the £240,000 valuation, that produces a maximum gross figure of £168,000.
The buyer therefore has a £12,000 gap between the loan and purchase price before allowing for fees and other acquisition costs.
Another lender could assess exactly the same property differently and base its advance on £180,000 instead.
This is why obtaining an agreement in principle based on the actual circumstances of the BMV transaction can be more useful than simply looking at a lender’s headline maximum LTV.
Can the discount replace some or all of your deposit?
Potentially, but this should not be assumed.
If the difference between the purchase price and the accepted market value is large enough, a specialist lender’s advance against market value could cover a very high proportion of the price you are actually paying.
In some circumstances it can potentially reach the full purchase price.
That does not necessarily mean that you can purchase a property without putting in any money whatsoever.
There may still be:
- lender arrangement fees;
- legal costs;
- valuation fees;
- interest;
- Stamp Duty Land Tax or the relevant property transaction tax;
- refurbishment expenditure; and
- other acquisition costs.
Lenders can also impose their own minimum borrower contribution.
This is a good example of why lender criteria should not be generalised. United Trust Bank’s published bridging criteria currently say that, for an undervalue purchase, it may calculate LTV from market value following a full valuation, but its criteria also require applicants to contribute at least 10% towards the purchase price or provide additional security.
Another specialist lender could structure the transaction differently.
Risks and evidence lenders will want to see
A lender seeing a property worth considerably more than the price shown in the sale contract will normally want an explanation.
A genuine bargain can be perfectly acceptable. An unexplained difference between the transaction price and claimed value can require considerably more investigation.
Evidence you may need to provide
Depending on the lender and transaction, expect questions about:
Why the seller has accepted less
A lender may want a clear explanation of the circumstances behind the discount. Speed, condition, an off-market transaction or a connected-party purchase may all need further context.
How the higher value has been established
The lender is likely to rely heavily on its own valuation rather than an estate agent’s asking price or an investor’s estimate.
The buyer’s relationship with the seller
A transaction between unrelated parties can be assessed differently from one involving relatives, associated companies or other connected parties.
Marketing history
The lender may want to know how long the property has been available, its previous asking prices, whether it has been marketed normally and whether there have been previous sales.
The sale documentation
The memorandum of sale, contract and conveyancing documents help establish what is actually being purchased and for how much.
Your source of funds
Expect normal legal and lender checks around the money you are contributing to the purchase and associated costs.
Your exit strategy
The lender will want to understand how its money will be repaid, whether through refinance, sale or another acceptable source.
If refurbishment is part of the plan, details of the proposed works, costs and experience may also be relevant.
One current lender example shows how detailed these checks can become. United Trust Bank’s published criteria require a satisfactory rationale for the reduced price and, where the BMV property is the sole security, a full valuation rather than an automated or drive-by valuation.
Risks to consider before proceeding
The biggest risk is often valuation risk.
If you agree to purchase at £200,000 believing the property is worth £300,000 but the lender’s valuer assesses it at £230,000, the amount available could be substantially lower than you planned.
That can leave you needing to find additional cash at short notice.
There is also exit risk. A future mortgage lender does not have to accept the same valuation or lending basis used by your bridging lender.
Market conditions can change, refurbishment may cost more than expected and the property may not sell as quickly as anticipated.
Bridging finance is also short-term borrowing. If repayment is delayed, additional interest and potentially default charges can become significant.
Your exit strategy matters just as much as the purchase
Getting enough money to complete the BMV purchase is only half of the calculation.
Before lending, a bridging provider will normally want a credible method of repayment.
Common exits include:
- selling the property;
- refinancing onto a buy-to-let mortgage;
- refinancing onto another suitable longer-term facility; or
- repaying using proceeds from another clearly evidenced source acceptable to the lender.
If your plan relies on refinancing based on the property’s higher market value, check the likely refinance criteria before completing the purchase.
Refinancing soon after buying
The frequently discussed “six-month rule” is not one universal rule followed identically by every mortgage lender.
However, length of ownership can matter considerably when refinancing or dealing with recently purchased properties.
The UK Finance Mortgage Lenders’ Handbook requires conveyancers to report circumstances where an owner or registered proprietor has been registered for less than six months, while individual lenders then set their own policies.
Current lender entries demonstrate the variation. Foundation Home Loans, for example, normally requires six months’ ownership for remortgages but lists circumstances in which that requirement may not apply, including certain purchases originally funded by bridging finance. Other lenders impose different restrictions on sub-sales, back-to-back transactions and short ownership periods.
If your bridge depends on refinancing quickly, the intended exit lender therefore needs to be considered before you take out the bridge rather than after completion.
Are BMV bridging loans regulated?
Some bridging loans are regulated and others are not.
The position depends on factors including the borrower, security property, intended occupation and structure of the transaction.
The FCA’s definition of a regulated mortgage contract can include bridging loans where the relevant regulatory conditions are satisfied. In broad terms, this can include lending to an individual secured on land where at least 40% is used, or intended to be used, as a dwelling by the borrower or a related person, although there are specific exclusions and exceptions.
An investor purchasing a property purely for business or investment purposes may therefore be dealing with a different regulatory position from somebody using bridging finance in connection with their home.
If there is any uncertainty, it is sensible to establish the regulatory status with an appropriately authorised adviser before proceeding.
How can a bridging finance adviser help?
BMV bridging applications tend to involve more than simply comparing interest rates.
An adviser familiar with specialist bridging finance can look at:
- whether lenders are likely to accept the proposed BMV structure;
- whether lending will be calculated using purchase price or market value;
- how much cash you will actually need at completion;
- the strength of the valuation evidence;
- whether additional security could help;
- fees and interest as well as the headline LTV;
- the proposed exit strategy; and
- whether your intended refinance is realistic.
This matters because the highest advertised LTV is not necessarily the best indication of whether a lender will fund your particular transaction.
I Need Advice matches customers with mortgage advisers based on their circumstances and areas of experience. If you are buying a property below market value, the aim is to find an adviser familiar with bridging finance and the type of BMV transaction you are proposing.
Frequently asked questions
Can you get 100% bridging finance on a below market value property?
It may be possible for the bridging advance to cover 100% of the purchase price where the purchase price is sufficiently below the lender’s accepted market value and the lender’s maximum LTV allows it.
That is different from borrowing 100% of the property’s market value.
You may also need your own funds for legal fees, valuation costs, interest, taxes and other expenses, and some lenders require a minimum personal contribution regardless of the amount of equity within the deal.
Does an estate agent’s valuation prove a property is BMV?
No. An estate agent’s appraisal can be useful background information, but the bridging lender will normally rely on a valuation completed for its lending purposes.
A previous asking price also does not prove market value. A property advertised at £400,000 and sold for £350,000 may simply have been overpriced originally.
Can I use a BMV bridge for an auction purchase?
Potentially. Bridging finance is commonly considered where a purchase has a short completion deadline, including auctions.
However, an auction purchase is not automatically a below market value transaction. The lender will still assess the purchase price, property valuation, security, borrower and exit strategy.
If you plan to use bridging finance at auction, arranging the finance and valuation strategy before bidding can reduce the risk of discovering afterwards that the required loan is unavailable.
Can I refinance a BMV property immediately?
Sometimes, but lender criteria vary considerably.
Some mortgage lenders impose minimum ownership periods or additional checks where a property has recently changed hands. Others have exceptions for particular circumstances, including certain purchases originally completed using bridging finance.
A proposed quick refinance should therefore be checked before committing to the bridge.
Can I buy a property below market value from a family member?
There are lenders that can consider connected-party or family transactions, but these purchases can attract additional scrutiny.
The lender may want to establish the property’s genuine market value, why the discount is being given, whether any element is effectively a gift and whether the legal structure is acceptable.
Do not assume the difference between market value and purchase price will automatically be treated as your deposit.
What happens if the bridging lender’s valuation is lower than expected?
The maximum available loan may fall.
For example, if your calculations rely on borrowing 70% of a £300,000 valuation but the valuer assesses the property at £260,000, the same 70% LTV produces £182,000 rather than £210,000.
You would need to cover the resulting shortfall, renegotiate the purchase, provide additional security if acceptable or find an alternative finance structure.
That is why building some contingency into a BMV purchase can be particularly important.
Conclusion
Below market value bridging loans can help buyers complete genuine discounted property purchases where conventional finance does not provide enough flexibility or speed.
The key issue is not simply how large the discount looks on paper. A lender will want to establish the property’s genuine market value, understand why it is being sold cheaply and decide whether its lending should be based on the purchase price, valuation or another permitted basis.
Your exit needs equal attention. A bridge that works perfectly on completion can still create problems if the intended refinance lender does not recognise the anticipated valuation or is uncomfortable with the short ownership period.
If you are considering a BMV purchase, I Need Advice can help match you with a mortgage adviser experienced in bridging finance who can assess the proposed transaction, likely lender approach and exit strategy before you commit.
They are experienced, which can boost your chances of being approved.
