Buy to Let Bridging

Short-term finance to buy or refurbish a buy-to-let before it can take a term mortgage — including bridge-to-let structures with the exit built in.

A buy-to-let bridging loan — usually arranged as a bridge to let — is short-term finance for buying or refinancing a property that is not yet ready for a standard buy-to-let mortgage. You purchase and refurbish on the bridge, then exit onto a term mortgage once the property is lettable, often drawing capital back out against the improved value.

This page is for landlords and investors buying property that needs work, completing at auction, or repositioning an asset to raise its rental income. We arrange bridge to let across 135+ lenders, and we structure the exit before the bridge — because the loan is only as good as the way out of it.

Key facts

What it is: a short-term loan to purchase or refinance a property unsuitable for a normal buy-to-let mortgage, with a pre-agreed exit onto a term product.
Loan to value: most lenders go to around 75% gross on the bridging element. Because costs and retained interest are deducted up front, plan for a deposit of roughly 30%.
Term: typically 12 to 18 months. Two years is possible, but rare.
Interest: usually retained rather than serviced monthly, so there is nothing to pay during the works. The rate depends on the asset, its location, your credit position and the strength of the exit — rates move with the market, so we quote against your actual case.
The exit: built in on a true bridge to let — the lender underwrites the bridge and the buy-to-let mortgage at the same time.
Speed: well suited to auction purchases, where completion is usually required within 28 days.

How bridge to let works

A bridge to let is two products underwritten as one. The bridge funds the purchase and refurbishment; the buy-to-let mortgage is agreed at the outset as the exit. Provided the works complete as planned, the term mortgage is waiting — your borrowing at the end is secured, and the lender knows how it will be repaid.

Take a worked example. You buy a property for £100,000 and spend £20,000 on refurbishment. Finished, it should be worth £150,000 and let for £1,000 a month. The lender tests the bridging side first: is the budget realistic, and is the end value likely to be achieved? Then the buy-to-let side: does £1,000 a month cover the loan costs?

The exit mortgage is assessed against the higher post-works value. Refinance against £150,000 rather than £100,000 and part of your capital comes back out, ready for the next purchase.

Who it's for

The common thread is a property a term lender will not touch on day one. Typical cases:

Refurbishment before letting — the property is lettable but tired and dated, and works will lift both the value and the achievable rent.
Unmortgageable stock — structural repairs or a condition no buy-to-let lender will accept at purchase.
Auction purchases — a 28-day completion deadline that a standard mortgage application cannot meet.
Regulatory upgrades — works that bring a property up to the EPC C standard required for private rented homes by 2030.

The discipline underpinning all of these is the exit. If the refurbishment stalls and you are left with a property that is neither lettable nor saleable, the debt against it remains. We pressure-test the works budget, the end value and the rental assumptions first — viability from the outset is the whole game.

Costs and fees

Always account for a 2% arrangement fee paid to the lender, which is added to the loan. A valuation fee varies with the value of the property but is often around £500 to £1,000; a large asset undergoing major refurbishment needs a more detailed report and will cost more.

Budget around £2,000 for legal costs. With bridging loans you generally pay for both your own and the lender's representation, at roughly £1,000 each. On purchases, factor in the 5% additional-dwelling stamp duty surcharge alongside the loan costs.

Monthly interest is retained from the advance rather than serviced, which is why the usable loan sits below the headline 75%. A bridge costs more than a term mortgage by design; the comparison that matters is not the headline rate but the return — the equity created, the rent unlocked, the capital released at refinance.

The process

Enquiry. The property, the purchase route and the timescale, plus proof of ID, proof of address, evidence of deposit and your credit report — so we see exactly what the lender will see and pick the right one first time.
Appraisal. We work up the numbers: the cost of works (two or three builders' quotes, or your own schedule if you have the experience), the expected end value and the likely rent.
Lender match. Sometimes a single bridge-to-let product is right; sometimes bridging with one lender and exiting with another is more cost-efficient. We compare both routes.
Valuation and legals. We progress the valuation and legal work through to drawdown.
Conversion. Works finished, you trigger the switch to the buy-to-let product — revaluation to confirm the works and the value, rent evidenced, underwriting, offer, legals. Relatively painless at that point.

Frequently asked questions

How much deposit do I need for a bridging loan on a buy to let?

Most lenders go to around 75% gross on the bridging portion. With costs and retained interest deducted from the advance, plan for around a 30% deposit in practice.

How much can you borrow on a bridge to let?

The bridge is capped against the value at acquisition or refinance — around 75% with most lenders. The exit mortgage is assessed against the post-works value, so added value means capital back out at refinance.

Can I get a bridge to let with bad credit?

Yes. Bridging is led by the asset and the exit rather than a clean credit file. Provided the property has value, will let, and the rental income covers the exit loan, options exist — though rates and arrangement fees are likely to be higher.

How does the switch to the buy-to-let mortgage work?

Once the property is ready to let, you advise the lender and trigger the conversion. An application goes in, the property may be revalued to confirm the works — particularly after a long refurbishment, when the market may have moved — and the rental income is evidenced.

What are the risks?

The exit failing. Terms are short — typically 12 to 18 months — and interest is higher than a term mortgage, so an unfinished project leaves you holding expensive debt against a property that cannot yet earn. The numbers have to stack up before you start.

Why use a broker for bridge to let?

Some lenders are broker-only, so a broker opens the whole market rather than part of it. We can often negotiate rates and fees, and we will tell you when bridging with one lender and exiting with another beats a single packaged product.

Hello, joining us on this episode of the Bridging Finance podcast is Scott from Propertyze to explain how by to let bridging works. It's great to chat with you, Scott. How's it all going? Very well, thank you. Looking forward to this one. Good, good. Okay, well, let's get straight into the questions in that case. So first of all, of course, can I get a bridging loan on a by to let? How does it work? Yes, you absolutely can. We often refer to this as a bridge to let. So it's kind of a double whammy product, really. It's a short term loan used to purchase or refinance a property that isn't currently suitable for normal by to let or perhaps it needs a refurb. You want to increase the rental yield on the property, but you do want to keep it as a by to let

at the end. So a bridge to let you do that refurb with a pre-agreed exit strategy with that lender. So you get the by to let product at the end. Right. Okay, well, there we go. The best of both. I know that's cliche. Now you've touched on it there already. So let's see if you've got anything else to add here. So why would you need a bridging loan to purchase a by to let property? There are several reasons. Typically the main reason will be that the property needs a refurbishment. So it could be that the property is lettable, but it's a bit tired, a bit old, a bit dated, and you want to maximise the rental income from the property itself. You will increase the value so that the refinance gets you more money back out against the purchase price. So there's

that point. You could be buying an auction. Auctions usually have a 28-day turnaround time. So you need bridging finance for those. So there's a few different variables, but those are the two main reasons we see it. Right. Okay. So the two key reasons there. Now, again, we get this question. Questions on most of the episodes we cover on bridging actually. So what is an exit strategy for those that might be doing this for the first time? And why is this important? Do I need an exit strategy to secure a bridge to let? So an exit strategy is how you plan to repay the bridging lender. The bridging loan you've taken out to either purchase, reframe, whatever it might be. In the case of a bridge to let

product, it is built in. It's two separate products, but from the client's perspective, it is a single unit. The bank will underwrite the bridging loan firstly, but they will also underwrite the exit strategy at the same time. So you'll say, I'm buying a property for a hundred thousand pounds. I'm going to spend 20,000 pounds refurbing it. And when I'm finished, it'll be worth 150 and it will rent for a thousand pounds a month. They look at the viability of the bridging point. Is what you're spending reasonable? Is the GDV likely? Are you likely to get to 150,000 pounds at the end? And then they'll look at the buy to let side of things and say, we want to get to that size with a thousand pounds a month rental income. Does that cover the loan costs? And they'll underwrite both

portions and then come back to and say, it's kind of approved. So you know that as long as you action the refurbishment correctly, you'll get the exit as well. So it's comfortable for both you. You know that you're guaranteed to get the spicelat at the end and the bank is happy as well. They're going to be repaid. So it keeps everybody happy. Okay, brilliant. So hopefully that explains it there. Then when it comes to the exit strategy and what's involved with a buy to let or bridge to let. Now, how much deposit do you need for a bridging loan on a buy to let? So for the bridging loan portion, which is the front end of this particular product, most lenders will go to 75% gross, which means after deduction of costs and interests,

you will probably need around a 30% deposit because they'll retain some element of the interest. So I would budget probably for a 30% deposit. Okay, so that answers that there. And then just following on, how much can you borrow on a bridge to let mortgage? So the borrowing will be limited to the loan to value of the property at the point of acquisition or free finance at the start of the bridging loan. It'll be capped by 75% of the value then. And when you come to the buy to let, you're likely to have added some value to it. So it'd be 75% of that new value, which means you should release some money back out at that point in most cases. Right. Okay. So there we go. Now we've covered deposit, we've covered borrowing,

but what are the fees for bridge to let? What are the costs do we need to know about? Always account for a 2% arrangement fee paid to the lender and added to the loan. Other fees, valuation fee, depending on the value of the property, that can vary, probably 500 to a thousand pounds on a valuation fee, unless you've got a very large property and you're doing a very large refurbishment, which requires a bit more valuation report to be extended. So yeah, a thousand pounds on the valuation, legal costs, I would budget 2000 pounds for legal costs. I would probably cover most of it. In the case of bridging loans, you pay for both yours and the lender's thousand pounds each. So 2000 should probably cover that

portion too. The monthly interest on the bridging side will be retained. So the lender will keep back some of the money. So that's 75% we talked about earlier. They'll keep some of that back in a separate pot and they'll pay the interest every month, which the interest can vary between 0.6 and 1.2% a month, depending on how good the asset currently is, its location, your credit position and what the exit looks like as well. Right. The monthly interest will be retained as well. So yeah, those are the key costs. All the costs to consider there. OK, we're getting through these questions now. Let's look at this one next. So can you still get a bridge to let loan with bad credit? Yes, you can. There are lenders who cater to applicants with poor credit.

As long as the property has value, it's rentable, lettable and your extra stress actually stacks up. The rental income covers the loan amount required at the exit. Then you still have some options. The rates will be higher. The arrangement fees might be slightly higher, but it can still be done. Right. OK, so that's good news there if you're listening to this and that might apply to you in any way. Now, moving on, how does remortgaging work in this case? So once the property is ready, you've purchased, you've done the briefer and now it's ready to let. You advise the lender that you're now finished. You wish to kind of trigger the conversion to a buy to let portion, really. And they will just let us submit an application for probably need revaluing

at that point as well to confirm that the works have been done. The value is what we expected. The rental income is what we expected. In the case of perhaps you've had it on a bridging line for a very long time because the briefer was quite extensive, the market might have changed. So the valuation report will need to be done again. But then it goes through the usual processes. Valuational report comes back, it's underwritten. Offer comes out and you go to the legal. Right. So it should be relatively painless at that point. Okay. That's good then. A mini step by step break down there as well. Now, just to recap, you've covered a lot of these points, but what are the pros and cons of using a bridging loan to buy a let?

The pros really are the fast access to funds. So in the case of purchase, obviously that's a key point. Everybody wants to get started. The ability to buy a mortgageable property. So the asset is not suitable for letting currently. Needs significant refurbishment, which has structural damage at least be repaired. You can buy this with a bridging loan, which you couldn't do with a buy to let a mortgage outright. And flexibility and timing and strategy, depending on what your business model is. So some good pros there. The cons are a slightly higher interest rate. Short repayment periods, typically 12 to 18 months is what we see for unregulated. It can go to two years, but very rarely do we tend to do that.

Doesn't usually require it really. More risk if the exit falls through. So if you're unable to complete the refurbishment and you're left with a property that's not lettable, so therefore not really saleable, you get a nut with a debt against it, which you can't redeem. So you need to be mindful of that. So really you need to make sure the project is viable from the outset. Right. But coming back to the interest costs, interest rates can be higher and the risks can be higher, but the returns are also higher. So it depends on your attitude to risk as well. Right. OK. So it's all about weighing up those pros and cons there, isn't it? But some key pointers. OK, so we'll cover this question. How do I apply for bridging to purchase a buy to let?

Anything else we need to know within that process? The usual basics really will need proof of ID. So typically a passport, proof of address, usually a driving license, a bank statement for a deposit if it's a purchase, a clear exit strategy. So understanding whether you're planning to sell or refinance. In today's podcast, typically it's going to be a bridge to let. So we're keeping it to understanding what the rental income is likely to be and a copy of a credit report just so we can understand exactly what is on there, what the lender is going to see to ensure we pick the right lender from the start. An estimate of the refab works. So if you've had no experience, get two or three builders quotes in

just to kind of give you some estimates. If you've got experience, you've got to market up yourself anyway. Then the key point really is giving all this to a correct broker so that you end up with the right lender, the right package and hopefully a painless process. Yes, okay. And that leads us nicely on to that next question, Scott. You've demonstrated it there. How can a broker help? Any final thoughts? Yes, I mean, a broker is really the key point in this process. Some lenders won't deal with you directly. Some are broker only. Which, using a broker allows you to access everybody in the first instance, giving you a wider choice of options. But being able to identify lenders that are suitable for you,

having connections and relationships at those lenders can obviously ease some of the pain points you might find. Sometimes we can negotiate the rates for fees down, depending on what the case is. Plan an extra strategy so that might be that although some lenders offer a bridge to let product, the best option for you might be to bridge it with lender one and then take you to lender two for the exit because that overall works as a better cost efficiency. So lots of things to consider that a broker will cover off for you. Yes, definitely. Okay, there we go. We'll end on that note. Thank you ever so much for that, Scott, as always. Hopefully that has proved useful to anyone listening to this. And I'm sure we'll speak to you again on the podcast soon.

Look forward to it. Please note, some bridging finance is not regulated by the Financial Conduct Authority.
