Bridge-to-let finance from purchase to buy-to-let mortgage
Bridge-to-let finance helps property investors buy or refurbish a rental property quickly with a bridging loan, then move onto a long-term buy-to-let mortgage. At its strongest, both stages come from one lender and are agreed upfront.
We check that both stages work, on cash, valuation and rent, before you commit to costs. Rates from 0.53% a month on qualifying cases, including combined bridge and term facilities, with specialist buy-to-let exits from 5.69%.

The short version
- A bridge-to-let funds a purchase, and any works, quickly, then refinances onto a buy-to-let mortgage.
- Bridge-to-let covers three routes: a combined facility from one lender, linked offers from one lender, or a bridge then a separate buy-to-let.
- The more of the buy-to-let that is agreed upfront, the less can change before you refinance, but conditions still apply.
- The rent must pass the buy-to-let lender's rental cover test, usually 125% to 145% of a stressed interest rate.
- Plan the bridge term around works, letting, any ownership period and the mortgage process. 12 months is often more realistic than 6.
- Rates from 0.53% a month on qualifying cases.
What is a bridge-to-let loan?
Bridge-to-let is short-term bridging finance used to buy or refurbish a rental property, with repayment from a buy-to-let mortgage. In its fullest form, both stages are provided by the same lender and agreed upfront in one facility, with the buy-to-let available as an option.
Phase 1: the bridge
The bridge secures the property quickly, often within days to a few weeks. It suits auction purchases, chain breaks and properties that need renovation before they meet standard buy-to-let criteria.
Phase 2: the buy-to-let refinance
Once the property is habitable and tenanted, a standard or specialist buy-to-let mortgage repays the bridge. On some products the lender agrees this second stage at the outset.
The bridge gives you speed and flexibility: it can complete quickly, fund a property that isn't mortgageable yet, and pay for works. The buy-to-let mortgage provides the long-term borrowing once the property is in lettable condition and tenanted.
The key question is how firmly the buy-to-let exit is arranged at the start. That varies widely between lenders, and it affects cost, timing and risk.
Three ways to structure a bridge-to-let
The term bridge-to-let is used for more than one arrangement. What matters is how much of the buy-to-let stage is settled before you buy, and what still has to happen at the switch.
| Route | How it works | What to establish |
|---|---|---|
| Combined bridge and term facility | One lender, one facility agreement. The bridge and an optional buy-to-let facility are agreed upfront | Exactly what is contractually agreed, and what triggers the switch to the term facility |
| Same lender, linked bridge and buy-to-let offers | One lender issues a bridge offer and a buy-to-let offer at the same time | When the buy-to-let offer expires, and what reinspection, checks or legal work remain |
| Bridge, then separate buy-to-let | A bridge now, and a new buy-to-let application, often with another lender, when the bridge is ending | How credible the future mortgage is, and what could reduce the amount it lends |
Why the combined facility is different
It's easy to assume bridge-to-let simply means a bridging loan followed by any buy-to-let mortgage. In its fullest form it is one facility agreement from one lender, with the buy-to-let facility agreed upfront and available as an option. The buy-to-let terms are known from the start, and moving across is a switch within the agreement rather than a new mortgage.
Settling it upfront reduces
- The risk of criteria or rates changing before you refinance
- Repeat applications, and often repeat legal work
- A second set of arrangement fees on many products
Still to check on any route
- Conditions for the switch, such as finished works and a tenancy
- Offer expiry dates and any reinspection or valuation update
- Minimum interest, early repayment terms and product fees
Where the buy-to-let is optional, you can sell or refinance elsewhere instead, subject to any minimum interest or fees. A separate buy-to-let can still be the cheaper route when the exit is straightforward, so we compare the total cost of each.
How we check both stages before you commit
Before you pay for a valuation or legal work, we check lender appetite for the property and the works, the cash you need to complete, and whether the buy-to-let exit works on both valuation and rent.
Assess both stages
We look at the property, the works, the expected rent, your profile and the buy-to-let criteria, and discuss the case with suitable lenders before you commit.
Bridge completes
The bridge funds the purchase, and works funding where it's part of the facility. The term is set around the realistic timeline.
Works and letting
Works are completed, the property is let, and the evidence the buy-to-let lender needs is gathered.
Move to buy-to-let
Either the agreed switch onto the term loan, or a buy-to-let mortgage application that repays the bridge.
Worked example: does the whole deal work?
An illustration, not a completed case or a quote. It follows the cash from purchase to refinance, then tests what happens if things go less well.
If things go less well
| Scenario | Buy-to-let mortgage | Capital recovered | Cash left in |
|---|---|---|---|
| As planned | £176,250 | £49,429 | £34,181 |
| Valuation 10% lower (£211,500) | £158,625 | £32,156 | £51,454 |
| Rent 10% lower (£945) | £159,438 | £32,953 | £50,657 |
| Refinance 3 months later | £176,250 | £46,830 | £36,780 |
The bridge is repaid in every scenario here, but the cash you get back falls by up to about £17,000. With a higher bridge or thinner margins, a lower valuation or rent could leave a shortfall to fund. Use the calculator at the top of the page to test your own figures.
Rates, fees and eligibility at a glance
| Feature | Typical position |
|---|---|
| Loan to value | Typically up to 70% to 75% of the day-one value. Some refurbishment products lend more against the value after works |

Bridge-to-let rates and costs in detail
Bridge-to-let has two prices: the bridge rate while works and letting happen, and the buy-to-let rate afterwards. Model both, along with fees at each stage.
| Structure | Bridge rate from | Max LTV | Notes |
|---|---|---|---|
| Bridge with a separate buy-to-let exit | 0.53% pm | Up to 75% | Widest choice. Buy-to-let applied for at the end |
| Light refurbishment, then buy-to-let | 0.62% pm | Up to 75% | Refinance at the value after works |
| Combined bridge and term facility, residential | 0.53% pm | Up to 75% | Term rate set by the product. Fewer costs at the switch |
| HMO | 0.75% pm | Up to 75% | Exit onto a specialist HMO mortgage |
| Semi-commercial | 0.79% pm | Up to 75% | Bridge then commercial term loan on selected products |
Buy-to-let exit rates
The exit is usually onto a specialist buy-to-let mortgage. These lenders accept refurbished property, HMOs, limited companies and newer landlords, so their rates sit slightly above high street banks.
| Exit product | Rate from | Max LTV | Notes |
|---|---|---|---|
| Specialist buy-to-let, 5-year fixed | 5.69% pa | Up to 75% | Interest-only. Rental cover usually tested at the pay rate |
| Specialist HMO, 5-year fixed | 5.99% pa | Up to 75% | Rent assessed on the HMO letting |
| Product fee | Commonly 1% to 3% of the mortgage, sometimes with early repayment charges during the fixed period | ||
Indicative rates, October 2026. Rates change often and depend on LTV, property and borrower.
What moves the price
- LTV. Lower leverage usually means sharper pricing.
- Property type. Standard single lets price best. HMO and semi-commercial cost more.
- Works. Cosmetic works price better than structural or conversion work.
- Rental cover. Strong rent relative to the loan widens lender choice.
- Experience. Established landlords often get better terms than first-time investors.
Compare the mortgage rate and product fee together, because a lower rate with a larger fee can cost more overall. On a combined facility, you may avoid a second valuation, legal costs and arrangement fee at the exit. Whether that's cheaper overall depends on the figures, so we compare total costs, not headline rates.
Arrangement fees commonly 1% to 2%, often around 2%. No upfront Aura Capital broker fee. Any fee on completion is disclosed before you proceed.
Rental cover: will the rent support the mortgage?
Buy-to-let lenders size the mortgage partly on rent. They divide annual rent by a stressed interest rate and a cover ratio, usually 125% to 145%. If the rent doesn't support the mortgage you need, the buy-to-let may be smaller than planned.
Higher-rate taxpayers borrowing personally usually face a higher cover ratio, and limited companies often a lower one. Use the calculator above to test your own figures.
Bridge term and timing
Most bridge-to-let problems come from a term that's too short. Add up every stage before choosing one.
| Stage | Typical timing | Notes |
|---|---|---|
| Works | 4 to 16 weeks | Cosmetic work is quicker. Structural and HMO compliance work take longer |
| Letting | 2 to 6 weeks after works | Depends on location and rent level |
| Ownership period | Often 6 months from purchase | Many buy-to-let lenders require it before refinancing at the new value |
| Tenancy history | None to several months | Some lenders accept a new tenancy. Others want payment history |
| Mortgage application | 4 to 8 weeks | Longer for limited company applications |
A 6-month bridge often looks enough until works, letting, an ownership period and the mortgage process are added up. 12 months is a common starting point, and HMO conversions or heavier works may need more. Check minimum interest and early repayment terms, so a longer term doesn't cost more than it needs to.
What bridge-to-let is used for
Auction purchase to rental
Complete within the auction deadline, carry out any works, let the property and refinance. See auction bridging.
Buy, refurbish, refinance
Buy a property needing work, improve it, let it and refinance at the value after works to release capital. See light refurbishment bridging.
Single let to HMO
Fund the purchase and conversion, obtain any licence, then refinance onto a specialist HMO mortgage. See HMO bridging.
Unmortgageable property
A property that can't be mortgaged today because of its condition or use, bought by bridge and refinanced once it qualifies.
Tight purchase deadlines
Where a buy-to-let mortgage can't complete in time, the bridge completes first and the mortgage follows.
Semi-commercial stabilisation
A mixed-use building that needs letting or works before it meets commercial mortgage criteria. See commercial bridging.
Bridge-to-let through a limited company or SPV
Many landlords now buy through a limited company or SPV, and most bridge-to-let lenders accept them, including newly formed companies. Directors usually give personal guarantees on both the bridge and the buy-to-let, so their credit and circumstances matter from the start.
Whether a company suits you is a tax and legal question, so take advice from an accountant before deciding. Tell us the full company and director picture early, because on an agreed structure the buy-to-let lender's criteria apply from day one.
Who can borrow
Borrowers
Individuals, limited companies, LLPs and SPVs. First-time and experienced landlords. Non-UK nationals with selected lenders. Adverse credit considered by some lenders.
Property
Single lets, HMOs, multi-unit blocks, and semi-commercial with selected lenders. Vacant and refurbishment properties. Minimum values apply.
Bridge-to-let is for investment property. If you or a close family member will live in the property, the loan may be regulated. Aura Capital doesn't give regulated advice and refers these cases to an FCA-authorised adviser. See regulated bridging loans.

Bridge-to-let FAQs
What is a bridge-to-let loan?
Short-term bridging finance used to buy or refurbish a rental property, repaid by moving onto a buy-to-let mortgage. In its fullest form, both stages come from one lender and are agreed upfront in one facility, with the buy-to-let available as an option.
Is a bridge-to-let just a bridging loan followed by a buy-to-let mortgage?
The term is sometimes used that way, but the strongest form is a single facility from one lender, with the buy-to-let agreed upfront and optional. Linked offers from one lender sit in between. A bridge followed by a separate buy-to-let needs a new application, valuation and legal work when the bridge ends.
Is the buy-to-let exit guaranteed on an agreed structure?
No. It can reduce uncertainty, but the switch depends on the conditions in the offer, such as completed works, a tenancy, a minimum period or a valuation update. The bridge term should leave time to meet them.
What rates are available?
Rates from 0.53% a month on qualifying cases, including combined bridge and term facilities. The buy-to-let rate depends on the product and market at the time.
How long should the bridge term be?
Long enough for works, letting, any ownership period the buy-to-let lender requires and the mortgage process, with time to spare. 12 months is a common starting point, and heavier works or HMO conversions may need longer.
What is the 6-month rule?
Many buy-to-let lenders want you to have owned the property for 6 months before they'll lend on its new value. Some lenders, and some agreed two-stage products, work differently, so check before choosing the bridge term.
How much rent do I need?
Buy-to-let lenders usually want annual rent of 125% to 145% of the interest at a stressed rate. At a 5.69% five-year fixed rate and 125% cover, £1,050 a month supports a mortgage of about £177,153. Lender assumptions vary.
Can a limited company get bridge-to-let?
Yes, including new SPVs. Directors usually give personal guarantees on both stages. Take tax advice on whether a company suits you.
Can I use bridge-to-let for an HMO?
Yes. The exit is onto a specialist HMO mortgage, and the bridge term needs to cover works and any licensing. Not every agreed two-stage product includes HMOs.
Can I get bridge-to-let with bad credit?
Some lenders consider adverse credit on the bridge. The buy-to-let lender will also look at your credit, so we check both stages at the start.
