Bridge to Let Mortgages
One arrangement fee. One underwrite. One survey process. Bridge to let mortgages combine the speed of a bridging loan with the certainty of a buy-to-let exit, all in a single product.
If you’ve spotted a property that needs work before a tenant can move in — or one the high street won’t touch until it’s back up to standard — a bridge to let is often the cleanest way to buy, refurbish and let.
What a bridge to let actually is
At its core, a bridge to let combines two products into one arrangement:
- A short-term bridging loan to buy the property and fund the refurbishment
- A buy-to-let mortgage underwritten upfront as the exit
The important difference from a standalone bridging loan is that the buy-to-let exit isn’t left to arrange later. Both parts of the deal are underwritten together at the outset, so the lender already knows how you’ll come off the bridge before you complete on the purchase.
That saves you two separate application processes, two arrangement fees, and — most importantly — the risk of finding out six months in that no buy-to-let lender will touch your refurbished property.
How it works
The process moves in two phases.
Phase one — purchase and refurbish. The bridging finance completes the purchase, often at auction or where the seller needs a quick sale. You then use the same facility to bring the property up to a habitable standard: new kitchen, bathroom, rewire, plumbing, whatever’s needed. Timescales here are typically 6 to 12 months, sometimes longer if the works are extensive.
Phase two — the buy-to-let exit. Once the works are signed off, the arrangement switches to the buy-to-let mortgage that was underwritten at the start. The surveyor returns for a final inspection to confirm the property is now in lettable condition. There’s no re-application, no fresh underwrite, and no fresh legal charge to register.
What the lender needs at the switch: a satisfactory revaluation, a signed assured shorthold tenancy (AST) with paying tenants in place, proof of first month’s rent received, and — for HMOs — the appropriate HMO licence. This is administrative rather than a fresh underwrite, provided the property and rental income meet the criteria agreed at outset. Typical timeline from purchase to exit switch is 3–9 months depending on the scope of works.
Why brokers recommend it over two separate products
Costs are the obvious one. The conventional route — bridging loan followed by a separate buy-to-let remortgage — means two arrangement fees, two full legal processes, and two rounds of underwriting. A bridge to let usually rolls those into a single arrangement fee (typically around 2% of the loan) and one legal charge.
Certainty is the less obvious but often bigger benefit. Standalone bridging loans leave the exit on your shoulders. If the buy-to-let market shifts, if your income situation changes, or if the property surveys down after the works, you can find yourself scrambling for an exit with a bridging loan clock ticking. A bridge to let removes that exposure — the exit is priced and agreed upfront.
Who it's built for
Bridge to let is designed for professional and portfolio landlords, including limited-company purchases and larger BTL portfolios. The buy-to-let mortgages we arrange as the exit sit outside FCA regulation — Consumer Buy-to-Let arrangements (small landlords whose lending falls inside FCA scope) aren’t something we place, and we’ll flag it early if your circumstances point that way.
Experience helps but isn’t mandatory. Most bridge to let lenders prefer borrowers with at least one existing BTL property, and some require it. First-time landlords can still qualify with a subset of lenders where the deal is straightforward — standard construction, simple refurbishment, clear rental market — though usually at slightly tighter LTV and higher rates.
Within that scope, common scenarios include:
- Auction purchases where completion is required inside 28 days and there’s no time for a conventional buy-to-let application
- Unmortgageable properties — no working kitchen or bathroom, structural issues, or long-term voids
- HMO purchases where the property will be reclassified after works
- Properties that don’t yet meet buy-to-let rental cover requirements but will once refurbished
- Investors let down late in the process by a conventional buy-to-let lender
A word on HMOs
Bridge to let works well for straightforward HMO purchases and light-touch conversions, where the property is already close to HMO standard or needs modest work.
For heavier build-out — knocking through walls, adding en-suites, converting a family home into a six-bed HMO — bridge to let often isn’t the right product. Most bridge to let lenders won’t fund extensive build works and will want the refurbishment costs paid in stages from your own funds. In those cases, development finance is usually a better fit, with a switch to an HMO buy-to-let mortgage once the build completes.
If you’re not sure which side of that line your project sits, get in touch and we’ll talk it through.
The commercial detail
- Bridging phase term: typically 6 to 12 months. Some lenders set minimum terms, others don’t — matching you to the right lender based on your projected works timescale is part of what we do
- Buy-to-let exit term: standard buy-to-let terms once the loan converts
- LTV at purchase: typically up to 75% of the purchase price
- LTV at exit: typically up to 75% of the refurbished value, with up to 80% possible on strong-yielding properties such as HMO conversions, subject to lender confirmation in advance
- Arrangement fee: typically around 2%, covering both parts of the arrangement
- Legal and survey fees: charged separately
- Refurbishment funding: in addition to the purchase LTV, additional funding is often available for refurbishment costs — in some cases up to 100% of the works budget, subject to lender confirmation and a costed schedule of works
When a bridge to let isn't the right choice
Bridge to let carries bridging-loan interest rates during the refurbishment phase. If the property is already mortgageable and in a lettable condition, a straight buy-to-let mortgage will almost always work out cheaper. Bridge to let earns its keep on properties a conventional lender won’t take on at outset — pushing it onto a project that doesn’t need it just costs you money.
The other watch-out is the exit. However confident you are about the refurbishment, work through three numbers before you commit:
- Will the post-works valuation service the buy-to-let loan you’re planning?
- Will the projected rent cover the buy-to-let affordability calculation with a reasonable margin?
- Have you built in contingency for the refurbishment running over on cost or time?
Get those three answers straight before anything else.

What is a bridge to let mortgage?
A bridge-to-let is a two-part facility from a single specialist lender: short-term bridging finance to fund the purchase (and refurbishment if needed), followed by an automatic switch to a longer-term buy-to-let mortgage once the property is habitable, let, and generating verifiable rental income. The bridge and the exit BTL are underwritten together at application, giving you certainty of exit before you complete the purchase. One application, one lender, one legal process.
When should I use bridge to let instead of standard bridging?
Bridge to let suits landlords buying a property that isn't currently mortgageable but will be after work is complete — ex-council flats, non-standard construction, properties needing full refurbishment, or HMO conversions. Standard bridging is faster and more flexible on purchase-to-refinance timelines, but leaves the borrower to find and secure the BTL mortgage separately, and takes the exit risk. Bridge to let removes that exit risk in return for higher upfront underwriting and slightly less flexibility on the exit terms.
Which properties are typically funded with bridge to let?
The strongest bridge to let use cases:
- Ex-council and non-standard construction — steel-framed, concrete-frame, deck-access flats that mainstream BTL lenders decline but specialist bridge to let lenders will fund.
- Refurbishment plays — buy a property that needs kitchen, bathroom, wiring, or full renovation, then refinance to a BTL mortgage once the work is complete and let.
- HMO conversions — buy a single dwelling, convert to a licensed HMO, refinance to a specialist HMO mortgage on the higher rental value.
- Auction purchases — 28-day completion with the certainty that the exit BTL is already agreed.
- Portfolio additions — professional landlords adding stock where the existing mortgage panel won't fund the specific asset.
What LTV can I get on a bridge to let facility?
Bridging phase LTV is typically up to 75% of purchase price, with additional funding available for refurbishment costs (in some cases up to 100% of the works budget, subject to lender confirmation). Exit BTL LTV is typically up to 75% of the post-works market value, with up to 80% possible on strong-yielding properties such as HMO conversions, subject to lender confirmation in advance. The critical calculation is that the post-refurbishment rental income needs to pass the exit BTL stress test — usually 125% or 145% of the mortgage payment at a stressed rate around 5.5%. If the numbers don't stack up at the exit stage, the deal doesn't complete.
How does the exit to the BTL mortgage work in practice?
Once the property is habitable and let with an assured shorthold tenancy in place, the lender re-values the property and switches the facility from bridging to the pre-agreed BTL mortgage. Standard evidence at that point: a satisfactory revaluation, a signed AST, proof of first month's rent received, and (for HMOs) the appropriate licence in place. The switch is administrative rather than a new application, provided the property and rental income meet the criteria agreed at outset. Typical timeline from purchase to exit switch: 3–9 months depending on the scope of works.
Do I need to be an experienced landlord to qualify for bridge to let?
Experience helps but is not always mandatory. Most bridge to let lenders prefer borrowers with at least one existing BTL property, and some require it. First-time landlords can still qualify with a subset of lenders, particularly if the deal is straightforward — standard construction, simple refurbishment, clear rental market. First-time landlord bridge to let often carries slightly tighter LTV and higher rates. For portfolio landlords, most lenders will consider up to 10 existing properties within a portfolio calculation, some more.
What are typical bridge to let rates and fees?
Bridging phase rates typically from 0.85% pcm — slightly higher than standard bridging because the lender is committing to the exit BTL at the same time. Arrangement fees usually around 2% of the bridge facility, covering both parts of the arrangement. Exit BTL rates depend on prevailing market rates at switch time but are typically fixed within a range agreed at underwriting. Total cost is higher than pure bridging plus a separate BTL remortgage, but is offset by the certainty of exit and the removal of a second full application. Every deal is priced individually.
Can I use a bridge to let loan for an HMO?
Yes, for straightforward HMO purchases and light-touch conversions where the property is already close to HMO standard. For heavier conversion work — structural changes, extensive building — development finance is usually a better fit, with a separate switch to an HMO buy-to-let mortgage once the build is complete.
