Buy to Let Criteria

An understanding of what lenders are looking for
Before you apply for a buy-to-let mortgage, it’s important to understand what lenders expect. The criteria for a buy-to-let mortgage are slightly different from standard residential loans, and knowing the key requirements can save you time, hassle, and missed opportunities.
We help landlords, new and experienced, meet buy-to-let mortgage eligibility standards and secure the right deal for their property plans.
Core conditions for buy-to-let mortgage approval
Deposit (loan to value):
Most lenders require a minimum deposit of 20–25%. That’s an LTV of 75–80%. The lower your LTV, the better your rates tend to be.
Rental income:
Your expected rent must typically cover 125%–145% of the monthly mortgage payments (stress-tested at a higher interest rate). This is known as the rental coverage ratio.
Property type:
Lenders prefer standard residential properties like houses and flats. Some will also accept HMOs, student lets, or flats above commercial premises, but this varies by lender.
Applicant type:
You can apply as an individual, limited company, or SPV. Some lenders only work with company structures, while others focus on personal buy-to-let borrowing.
Experience:
Some lenders require previous landlord experience, especially for HMOs or larger portfolios. However, we also work with lenders who support first-time landlords.
Age and income:
Most lenders set minimum and maximum age limits (usually 21–85). While personal income isn’t always a major factor, some lenders may have minimum income thresholds, particularly for first-time landlords.
Credit profile:
Clean credit is preferred, but we can place deals with lenders who consider adverse credit, CCJs, or missed payments, provided the rest of the application is solid.

Buy-to-let mortgage example
Let’s say you’re buying a property worth £200,000 with an expected rental income of £1,000/month.
You want to borrow £150,000 (75% LTV).
The lender stress-tests your rent against a notional interest rate of 5.5%, requiring rental cover of 145%.
- Required rent: £150,000 x 5.5% = £8,250 annual interest
- £8,250 x 145% = £11,962.50 minimum required rent
- Monthly requirement = £997 approx.
In this case, your projected rent meets the lender’s buy-to-let mortgage criteria in the UK, and you’d likely pass affordability, assuming credit and property standards are also met.
