Ask most property investors what a bridging loan costs and they will probably give you a monthly interest rate.
Something like:
0.65% per month.
At first glance, that may not sound particularly expensive.
But that number is only one part of the equation.
The real cost of bridging finance can include:
And for an auction buyer, there is another cost that is often overlooked:
A bridge that looks cheap on paper can become expensive if the transaction takes longer than expected, the exit is delayed, the valuation comes in below expectations or the buyer discovers additional costs after winning the property.
That is why experienced property investors do not simply ask:
"What is your bridging rate?"
They ask:
"What is the total cost of borrowing, how is it calculated, and what will I actually need to repay when I exit?"
That is the question this guide answers.
There is no single bridging loan price that applies to every borrower.
The cost depends on the individual transaction.
Important pricing factors can include:
Current market examples published in 2026 show indicative bridging rates ranging from roughly 0.4% to 1.5% per month, depending heavily on the transaction. Arrangement fees are commonly around 1%–2%, while some products also carry exit fees. These figures are market indicators rather than guaranteed rates for any particular borrower.
MoneySavingExpert's current guidance similarly notes that bridging rates can range from around 0.5% to 2% per month depending on circumstances and highlights additional costs such as arrangement, legal, valuation and administration fees.
That variation is important.
A borrower with a low LTV, straightforward residential property and strong exit may receive significantly different pricing from someone seeking high-LTV finance on a complex auction property requiring substantial refurbishment.
So when somebody asks:
"How much does bridging finance cost?"
The honest answer is:
The cost of bridging finance depends on the property, loan structure, LTV, borrower profile, term, lender and strength of the exit strategy.
But you can understand the cost structure before you approach a lender.
Think about a bridging loan as a stack of costs rather than one price.
Not every bridge will contain every fee.
Some lenders may offer no exit fee. Some brokers charge a fee and others may be paid differently. Some lenders may contribute towards certain costs.
The point is to understand the complete fee structure before comparing offers.
Interest is normally the largest component of bridging finance.
Unlike conventional mortgages, bridging rates are commonly quoted per month rather than as an annual percentage.
For example:
0.75% per month
That does not mean the annual cost is simply 0.75%.
If charged on a simple basis for 12 months, it would represent 9% of the original balance. If monthly interest were compounded, the effective annual cost would be higher.
MoneySavingExpert illustrates the point with a 2% monthly rate: over 12 months, the equivalent annual cost would be approximately 26.82% when compounded.
However, auction investors should not automatically convert a monthly bridging rate into an APR and assume that tells the whole story.
A bridge is a short-term product.
How much interest will I actually pay over the period I expect to use the bridge?
Suppose you borrow:
£200,000
At:
0.75% per month
The simple monthly interest would initially be:
£1,500 per month
If the bridge lasts six months, that would be approximately:
£9,000
before considering how the lender calculates interest, whether interest is rolled up, whether the balance changes and any other fees.
That is much more useful to an investor than simply seeing "0.75%".
The arrangement fee is the lender's charge for setting up the bridging facility.
It is often calculated as a percentage of the loan.
Current market examples commonly show arrangement fees around 1%–2% of the loan, although the exact fee varies by lender and transaction.
Consider a:
£200,000 loan
with a:
2% arrangement fee
The fee would be:
£4,000
That £4,000 needs to be included in your project calculations.
It may be:
The treatment matters.
Suppose you need £200,000 net to complete.
If the arrangement fee is deducted from the advance, you may not actually receive £200,000.
You might need to borrow more or contribute additional cash.
This is one reason borrowers should distinguish between:
Gross loan and Net advance available to complete.
For auction buyers, that distinction can be critical.
Before a lender advances funds against property, it generally needs an appropriate valuation of the security.
The valuation cost depends on:
Current market guidance suggests valuation costs can range from hundreds to several thousand pounds depending on the property and complexity.
For a straightforward residential auction property, the valuation may be relatively straightforward.
For a complicated commercial property or development opportunity, it can be considerably more involved.
The valuation fee is a transaction cost. Include it in your acquisition budget before you bid.
Bridging finance involves legal work.
And there are usually two sides to consider:
Your solicitor and the lender's solicitor.
Depending on the transaction, you may therefore need to budget for both your own legal costs and the lender's legal costs.
Current market guides indicate that combined legal costs can run into several thousand pounds, particularly where the transaction involves multiple securities, commercial property, development, complex title issues or other complications.
For auction buyers, this becomes particularly important because there may already be substantial legal work required around the auction purchase itself.
The legal pack should therefore not be treated as a document you look at after winning.
RICS advises auction buyers to thoroughly research the legal pack, conditions of sale and other information before bidding. It also specifically notes that buyers need to arrange finance for both the deposit and completion.
If a property has:
The legal process may become more involved.
That can affect both the cost and the speed of your funding.
Some bridging lenders charge an exit fee when the facility is redeemed.
Others do not.
Where an exit fee applies, it may be calculated as a percentage of the loan.
Current market examples show exit fees ranging from 0% to around 1.5%, depending on the product and transaction.
For example: Loan: £200,000 Exit fee: 1% Exit cost: £2,000
This is another reason why comparing rates alone can be misleading.
Lender A Lender B
Which is cheaper?
There is no way to answer without knowing:
A lower headline rate does not automatically mean a lower total cost.
A bridging transaction can also involve broker fees and administration charges.
Broker fees vary considerably.
Some brokers charge a percentage of the loan. Some charge a fixed fee. Some may have different arrangements depending on the transaction.
You should understand:
The same applies to administration charges.
Never assume that a fee is insignificant simply because it appears as a small line on a quote.
The objective is to calculate the complete cost of the transaction.
Let's make this practical.
Suppose you borrow:
£250,000
at:
0.75% per month
Initial monthly interest:
£1,875
If you hold the bridge for six months and interest is calculated simply on the initial £250,000 balance, that is approximately:
£11,250
in interest.
Now add:
That means the headline:
0.75% per month
does not tell you that the transaction could cost approximately £22,750.
This is a simplified illustration, not a quotation. Actual costs vary by lender, facility structure and transaction.
But this is precisely the calculation an auction buyer should perform before bidding.
Let's take a realistic hypothetical auction scenario.
Auction purchase price: £200,000 Bridging loan: £150,000 £50,000
Assume:
0.75% per month
Initial monthly interest:
£1,125
If held for six months:
£6,750
Assume:
2%
£150,000 × 2% =
£3,000 £750
Assume combined borrower/lender legal costs of:
£2,000
Assume:
1%
£150,000 × 1% =
£1,500
£6,750 + £3,000 + £750 + £2,000 + £1,500
= £14,000
So the buyer is not really asking:
"Can I borrow £150,000 at 0.75%?"
They should be asking:
"Can my project absorb approximately £14,000 of finance costs over the expected six-month period, plus the other acquisition and refurbishment costs?"
That is the investment question.
Interest is time-sensitive.
The longer you borrow, the more interest you generally pay.
Consider a £200,000 loan at 0.75% per month.
*Illustrative simple calculation using the initial £200,000 balance. Actual interest treatment varies by lender and facility.
The difference between three months and twelve months is:
£13,500
That is why the exit strategy matters so much.
If your plan is to refinance after refurbishment, you need to think realistically about:
A six-month bridge is not necessarily a six-month project.
You need to allow time for things to go wrong.
One important question to ask when comparing bridging loans is:
How is the interest paid?
There are several structures.
You make interest payments during the term. This creates a regular cash-flow requirement.
Interest for the expected term may be retained from the facility at the outset.
Interest accumulates and is paid when the loan is redeemed.
The structure affects the amount of cash you need at the start and how interest is calculated.
It also affects the effective economics of the loan.
For example, if interest is added to the outstanding balance, the amount owed can increase over time.
Ask your lender or broker for the actual estimated redemption figure under the proposed structure rather than trying to calculate it from the headline rate alone.
Generally, lower-risk transactions can attract more competitive pricing, and LTV is one of the factors lenders consider.
A borrower putting in more equity may present less risk to the lender than someone seeking a high-LTV facility.
Current market pricing tables demonstrate this relationship, with indicative rates generally increasing at higher LTV bands.
But LTV is not the only factor.
They may have the same LTV.
They do not necessarily represent the same risk.
The lender's pricing and appetite can therefore be very different.
Auction properties are not automatically more expensive to finance.
But certain characteristics common in auction purchases can make a transaction more complex.
For example:
The issue is not that the word "auction" appears in the transaction.
The issue is the underlying risk.
RICS advises buyers to research the property particulars, legal pack, conditions of sale and any addendum before bidding. It also highlights that buyers must arrange finance for the deposit and completion.
This is why a proper auction finance assessment should happen before the hammer falls.
There is a subtle but important distinction.
Cheap finance means the quoted borrowing rate or fee is low.
Cheap money means the entire transaction costs less.
Those are not always the same thing.
If Option B allows you to complete successfully while Option A creates a timing problem, Option B may be the economically better choice.
The objective should therefore be:
Lowest appropriate total cost
—not:
Lowest advertised rate.
You cannot eliminate the cost of borrowing.
But you can often improve the economics of a transaction by managing the structure properly.
The less you borrow, the less interest you generally pay.
If additional equity allows you to reduce the bridge from £200,000 to £150,000, the interest saving can be meaningful.
Every additional month can add interest.
Have your solicitor, broker, valuer, contractor and exit lender lined up as early as practical.
A credible exit can influence lender appetite and pricing.
For a refinance exit, understand the likely long-term lending criteria before taking the bridge.
Do not compare monthly rates in isolation.
Compare:
Interest + arrangement fee + valuation + legal + broker + exit fee + other charges
If you expect to refinance in four months, check whether the lender allows early redemption without an additional penalty.
Some facilities are designed with flexible early repayment, while others may have minimum interest periods or other conditions.
An auction property with an unexpected legal complication can cause delay and additional expense.
RICS specifically recommends thorough review of the legal pack and keeping in contact with the auctioneer because amendments can be issued before the sale.
Do not structure the deal so tightly that one contractor delay destroys the economics.
Imagine you receive two offers.
At first glance, Offer A looks cheaper.
Interest:
£250,000 × 0.70% × 9 = £15,750
Arrangement:
£250,000 × 2% = £5,000
Exit:
£250,000 × 1% = £2,500
Subtotal:
£23,250
Interest:
£250,000 × 0.78% × 9 = £17,550
Arrangement:
£250,000 × 1% = £2,500
Exit:
£0
Subtotal:
£20,050
Before valuation and legal costs, the apparently more expensive monthly rate is actually cheaper by:
£3,200
This is why sophisticated borrowers compare the whole fee stack.
One of the most useful lessons from day-to-day property finance is that the "best rate" often isn't the same thing as the "best deal."
A transaction has a timeline.
The auction has a deadline.
The solicitor has a workload.
The lender has underwriting requirements.
The valuer has to inspect the property.
The exit lender may have its own criteria.
Every additional complication can affect the probability and cost of completion.
For an auction buyer, therefore, the right funding question is:
"Can this lender deliver the required amount, against this property, within this deadline, at a total cost that still leaves the project profitable?"
That is much more sophisticated than asking:
"Who has the lowest bridging rate?"
This distinction becomes particularly important when a buyer is bidding on a property because it appears to be below market value.
The margin in the property does not belong to you automatically.
You have to protect it.
And finance is one of the largest variables in that equation.
Before bidding, build this calculation:
Then compare that with your realistic exit value.
For example:
Realistic Exit Value: £300,000 minus Total Project Cost: £245,000 = £55,000 gross margin
Now stress-test it.
What if:
The £55,000 margin may suddenly look very different.
That is what proper auction finance analysis should uncover before you become legally committed.
At the end of the transaction, do not simply look at the interest paid.
Calculate:
Total finance cost ÷ original loan amount For example: Total finance cost: £20,000 Loan: £250,000
£20,000 ÷ £250,000 =
8% total finance cost
If you held the bridge for six months, that gives you a much clearer picture of what the funding actually cost the project.
This is particularly useful when comparing future deals.
You can begin to understand not just:
"What rate did I get?"
but:
"What percentage of my project capital did finance consume?"
That is the number an investor should care about.
Your exit strategy is directly connected to your finance costs.
Consider two investors.
Plans to refinance in six months.
Plans to sell but has no clear buyer profile, no realistic valuation evidence and no defined marketing strategy.
Investor A may have a stronger finance proposition because the exit is more clearly defined.
Start with:
How will I repay the loan?
Then work backwards:
This is particularly powerful for auction buyers because the purchase decision happens quickly.
Before accepting an offer, ask for a clear breakdown of:
The final question is particularly useful.
Instead of asking only:
"What is the rate?"
ask:
"If I borrow £X and redeem in six months, what is the estimated total amount I would need to repay?"
That gives you a much more useful basis for comparing funding.
This is an uncomfortable but important point.
Bridging finance is expensive.
But failing to complete an auction purchase can be considerably more damaging.
Under the RICS Common Auction Conditions, where applicable, completion is generally 20 business days after the auction unless the special conditions provide otherwise. RICS specifically warns buyers to check the special conditions and arrange finance for both the deposit and completion.
The precise contractual position depends on the auction terms.
Your finance must be assessed against the actual contract, not a generic assumption about auction timelines.
If you need finance quickly, the correct comparison is not:
"Bridge versus mortgage."
It is:
"Appropriate bridge versus the cost and risk of failing to complete."
That is a very different decision.
In Auction Demystified: Unlocking Auction Success, Deji Nehan explores the broader mechanics of buying property at auction, including the relationship between the property, legal pack, funding, refurbishment and exit.
The principle is particularly relevant to bridging costs:
A successful auction purchase is not simply about buying below value. It is about understanding the complete transaction before you commit.
The finance cost is one part of that equation.
The legal position is another.
The refurbishment budget is another.
And the exit is arguably just as important as the entry.
That is why experienced auction buyers analyse the deal as a complete system rather than focusing on the headline purchase price.
There is no fixed cost. Current market examples show bridging rates commonly quoted on a monthly basis, with indicative rates varying significantly according to LTV, property type, borrower profile and exit strategy. Arrangement fees are often around 1%–2%, with valuation, legal and potentially exit fees added.
Bridging rates vary by transaction. Current 2026 market examples show indicative rates from below 0.5% per month for some lower-risk facilities to above 1% per month for more complex transactions. These are indicative figures rather than guaranteed rates.
Generally, bridging finance has a higher short-term cost than conventional mortgage finance. However, it serves a different purpose and can provide speed or flexibility where a mortgage is unsuitable or cannot complete within the required timeframe.
Potential costs include interest, arrangement fees, valuation fees, legal fees, broker fees, administration charges and exit fees. Not every lender charges every fee.
Some bridging products have no exit fee, while others charge one. It depends on the lender and facility. Current market examples show exit fees ranging from zero to around 1.5% on some products.
This depends on the lender and the terms of the facility. Some lenders calculate interest only for the period the funds are outstanding, while others may have minimum interest periods or early repayment conditions.
Always check the terms before committing.
It can. Lower-LTV transactions may attract more competitive pricing because the lender has greater equity protection. However, property type, condition, borrower profile and exit strategy also influence pricing.
In some transactions, certain costs—including interest or arrangement fees—may be incorporated into the facility, subject to lender criteria and LTV limits.
This does not make those costs disappear. They still have to be repaid.
The biggest opportunities usually come from selecting an appropriate lender, reducing the borrowing amount, keeping the project on schedule, strengthening the exit and comparing the complete cost of competing facilities rather than only the monthly rate.
If you are relying on finance to complete an auction purchase, establishing your funding position before bidding is strongly preferable.
RICS advises auction buyers to arrange finance for both the deposit and completion and to understand the auction's specific completion requirements before bidding.
A bridging loan quoted at 0.70% per month may sound attractive.
But that number tells you almost nothing about the actual cost until you know:
For an auction buyer, there is one more question:
Because the best bridge is not necessarily the one with the lowest monthly rate.
It is the one that provides the right amount of capital, against the right property, within the required timeframe, at a total cost that still makes the investment work.
