Buy to Let Mortgage Rates
& Lending Outlook in 2026
The Buy to Let market in 2026 is stabilising following previous rate increases. Lenders continue to refine affordability assessments, and rental demand remains strong across many regions of the UK.
Key trends this year include:
-
- More competitive pricing returning at lower loan-to-value bands
- Continued growth in limited company borrowing
- Stress testing typically set between 125% and 145% of rental income
- Increased lender appetite for experienced and portfolio landlords
Rates and criteria vary significantly between lenders. Working with a specialist Buy to Let mortgage broker ensures you are matched with lenders aligned to your property type, rental yield and long-term strategy.
What Is a Buy to Let Mortgage?
A Buy to Let mortgage is designed for property investors who intend to rent out a property rather than live in it themselves.
Unlike residential mortgages, affordability is based primarily on projected rental income instead of personal earnings. Many products are structured on an interest-only basis, helping landlords maximise cash flow and yield.
Key Differences Between Residential and Buy to Let Mortgages
| Feature | Residential Mortgage | Buy to Let Mortgage |
|---|---|---|
| Purpose | Owner-occupied property | Rental investment property |
| Affordability | Based on personal income | Based mainly on rental income |
| Deposit | Often 5–10% | Usually 20–25% or more |
| Repayment | Capital and interest | Often interest-only |
| Regulation | FCA regulated | Usually unregulated |
If you are unsure which route applies to you, our advisers will assess your position and recommend the appropriate structure.
How Much Deposit Do You Need?
Most lenders require a minimum deposit of 25%.
Some specialist lenders may consider applications from 20%, depending on property type and rental yield.
Larger deposits generally provide:
- Access to lower interest rates
- Broader lender choice
- Improved stress test flexibility
We assess your borrowing power using both rental projections and lender stress testing models.
How Lenders Assess Affordability
Before approving a Buy to Let mortgage, lenders apply a rental stress test. This ensures that rental income covers mortgage payments even if interest rates increase.
Typically, lenders require:
- Rental income covering 125% to 145% of the mortgage payment
- Stress testing at a notional rate (often around 5.5% or higher)
- Minimum personal income (commonly around £25,000 annually)
Criteria vary widely between lenders, which is why broker-led lender selection can significantly improve approval prospects.
Unsure whether your rental income meets lender stress tests?
Who Can Apply for a Buy to Let Mortgage?
Most lenders expect:
- Minimum age 21
- UK residency
- Clean or manageable credit history
- Property value usually above £75,000
- Deposit of 20–25% or more
First-time landlords can apply, although criteria may be stricter.
If you have complex income, adverse credit or multiple properties, specialist lenders may still consider your case.
