Valuations are at the heart of bridging. They set your loan amount, your cash needed, and your timeline.
However, how fast you get a value depends on the valuation method. The method can mean a smooth process or delays, so it pays to know what to expect.
This article breaks down the 4 main valuation types, when each is used, and how a low figure hits your wallet. All examples use a £400,000 buy-to-let flat.
Why does the valuation matter more on a bridging loan?
Bridging lenders work under time pressure, so every decision is about speed and risk.
Mortgage lenders can wait years for the market. Bridging lenders, however, have 3-12 months. If your exit fails, they may need to sell quickly to recover funds.
In contrast, a bridging lender usually has just 3-12 months. If your exit strategy fails, the lender may have to sell the property quickly to recover its funds.
That is why lenders want 2 figures:
- Market value: what the property should sell for after normal marketing. This sets your loan-to-value.
- Restricted realisation value: what the property would fetch in a quick sale, usually 10-20% lower.
You likely never see the quick-sale figure, but it matters to the lender's risk team.
This is how the lender's credit team thinks about their risk and recovery. Even if everything looks good on paper, that hidden figure is one reason lenders remain cautious.
One rule applies: Your loan is always based on the lower of the price or valuation. If you pay £400,000 but the value is £360,000, your loan is on £360,000. The valuation is a ceiling, never a floor.
What are the four ways a lender can value your property?
The 4 valuation methods differ mainly by how closely a person examines the property. Each balances speed, accuracy, and cost differently.
No matter the method, the lender instructs the valuation from their own panel and you pay the fee.
Automated valuation model (AVM)
An AVM, or automated valuation model, is essentially a computer-generated estimate.
The system reviews HM Land Registry sold prices, current property listings, and details such as the property's size and type. From there, it produces a figure with a confidence indicator.
Keep in mind that these indicators vary by provider, so a letter grade from one AVM and a percentage from another are not directly comparable.
Desktop valuation
A desktop valuation is a report written by a qualified RICS surveyor who does not visit the property.
Instead, the surveyor selects comparable sales rather than relying on an automated model to pick them. In refurbishment cases, the surveyor can also offer an opinion on gross development value, or GDV, which is what the property should be worth once all planned works are complete.
Drive-by valuation
A drive-by valuation, also called an external valuation, sits between these 2 methods.
Here, the surveyor visits the property but inspects only the exterior. This approach is often faster than a full inspection but still provides more assurance than a desktop or AVM.
Red Book valuation
A Red Book valuation involves a full internal and external inspection.
It follows the RICS Valuation Global Standards, which the property industry calls the Red Book. Of the four methods, this is the most accurate and the most defensible.
While RICS also publishes guidance for valuations done without an inspection, it does not require lenders to use it.
What makes a lender ask for an inspection?
Lenders focus on risk, especially any factor that data alone cannot reveal.
There are 4 key factors that push a case up the ladder and trigger a more detailed valuation:
- A loan-to-value (LTV) ratio close to the lender's maximum. This leaves less margin for error.
- Works in progress. A gross development value (GDV) is only a forecast, not a confirmed figure.
- Thin comparable evidence. A weak AVM score signals limited market data.
- Any property that is not of standard construction or is located outside an established area.
Many overseas buyers believe new build properties are straightforward. In reality, they are not. Developer price lists sometimes exceed second-hand values, and new schemes often have limited resale evidence.
For these cases, lenders will usually require a desktop valuation or a physical inspection, rather than relying on a high-confidence AVM.
Sometimes, a desktop valuation will recommend a full inspection. This does not mean your application has failed. Instead, it shows the system is working to manage risk.
However, it can extend your timeline. When you make your enquiry, ask the lender which method they are likely to use. Lenders consider this along with all the other factors in your application.
Can your property be valued if you are not in the UK?
Yes, your location is rarely an obstacle. For 3 out of 4 valuation methods, it makes no difference where you are.
AVMs and desktop valuations need nothing from you. Drive-bys just need the street. Only a full inspection needs access, but if you are abroad, someone else can open up.
If access is needed, 1 of 4 people usually handles it:
- The developer or site sales team: This is routine for a new-build property.
- A letting agent: They hold keys on a tenanted property and can meet the surveyor.
- Your solicitor: They can coordinate with the seller's side, but this usually adds another step.
- A sitting tenant: They need notice, which is often the slowest route to access.
Do not expect access within 24 hours. This is common on an assured shorthold tenancy. However, licensed HMOs, older regulated tenancies, and uncooperative occupiers can take much longer to arrange.
That said, book access as soon as you instruct the valuation. Missing one appointment can set your completion timeline back by a week.
What happens if the valuation comes in low?
When a valuation comes in low, your loan amount shrinks, and your cash requirement grows faster than you might expect.
For example, a 10% drop in valuation cuts the loan by £30,000. However, the true cost to you is not just £30,000, because a bridging facility is quoted on a gross basis and fees are deducted from that amount.
2 main costs are deducted from your bridging facility before your solicitor receives any funds:
- A 2% handling fee
- 3 months of retained interest, calculated at 1% per month.
These deductions total roughly 5% of the gross loan. As a result, if your loan falls by £30,000, the related fees drop too, but your deposit must still cover about £28,500 extra.
A low valuation can also disrupt your exit plan. If you intended to refinance at £400,000, a £360,000 valuation will reduce the mortgage amount available to you. Always test your exit strategy using a lower figure to see if it still works.
If you receive a low valuation, you usually have 3 practical options. Try them in this order:
- Renegotiate the price. The new valuation shows what the seller must address.
- Ask the lender to review the valuation. To support your case, provide three recent and genuinely comparable sales.
- Finally, you can choose to fund the shortfall yourself if the other options are not possible.
What can you send the valuer?
Send the valuer any information they would otherwise have to chase down themselves.
- Access details: Provide the name and phone number of the person who holds the keys.
- Floorplan and EPC: These documents confirm the property's size and specification without needing a visit.
- Three comparable sales: Make sure they are recent, nearby, similar, and include full addresses.
- A refurbishment schedule: This should outline the costs and the expected end value.
Sharing these documents does not affect the valuer's independence. Instead, it helps to prevent unnecessary delays in the reporting process.
When should you want the slower valuation?
You should consider a slower valuation when you have never seen the property yourself.
An AVM, desktop report, or drive-by valuation all protect the lender's position. However, none of these methods is a full survey, and none involves inspecting the inside of the property. If you have not seen the building yourself, a fast valuation will not reveal issues like damp, subsidence, or cladding problems.
Here are 3 situations where a slower, more thorough valuation is often the better choice:
- If you have not seen the property, get your own survey in addition to the lender's report.
- For off-plan or new-builds, a physical inspection can reveal any gap between developer pricing and market value.
- For non-standard properties like conversions, desk valuations are less reliable. An inspection is safer.
Watch out for timing pitfalls. Most lenders consider a valuation current for about three months, but this is a policy, not a strict rule. Always check with your lender before you pay for a valuation, to avoid surprises later.
How does GoGoProp sequence a valuation?
We run an automated valuation as soon as an enquiry arrives. We escalate only where the case needs it.
That order exists because we lend against the asset, not your income or credit history. That makes the property's value the critical path.
An indicative figure on day one produces an initial decision within 24 hours. It also tells you which method your case needs at the start.
Our LTV is a fixed 75% for every borrower. It is based on the lower of the price and valuation.
Most lenders quote a range, so your cash stays unknown until the valuation lands. We publish full terms on our bridging loans page:
GoGoProp lends under Money Lending Licence No. 1341/2025.
Key takeaways
- Bridging lenders look for 2 figures. First is market value, which sets your loan-to-value. Second is the 90-day value, which tells their credit team how easily they could recover funds if they had to sell quickly.
- Your loan is always based on the lower of your purchase price or the valuation. Think of the valuation as a ceiling, not a floor.
- There are four ways to value a property: AVM, desktop, drive-by, and full Red Book inspection. The lender orders the valuation, you pay for it, and only the full inspection requires the surveyor to enter.
- If your valuation comes in 10% low, your loan could drop by £30,000, and your cash gap grows by about £28,500. That is because fees are deducted from the gross loan, not added on top.
- Remember, AVM, desktop, and drive-by reports are not surveys. If you have not seen the property yourself, take extra care. Any surprises inside are your responsibility.
FAQs
1. What is a 90-day value?
A 90-day value is the price your property would likely sell for if it had to go in three months. It usually sits 10% to 20% below market value.
2. Who pays for a bridging valuation?
You pay for the valuation once your case gets to that stage. The lender picks the surveyor, not you.
3. How accurate is an AVM?
AVM accuracy depends on the data. They work well for standard homes with lots of recent sales nearby, but are less reliable in slow or unusual markets.
4. Can you get a bridging loan without a valuation?
Almost always, you need a valuation. Lenders want a value to set the loan, but in simple cases, an AVM can sometimes replace a full inspection.
5. Can you challenge a down valuation?
You can ask the lender to review a down valuation, but you will need solid evidence. Three recent, truly comparable sales help make your case.
