What Is a Buy to Let Mortgage?
A Buy to Let (BTL) Mortgage is a loan used to purchase property that you intend to rent out to tenants. In the UK, Buy to Let Mortgages are interest-only or repayment-based and are assessed on both the applicant and the rental income of the property.

- Debt management plans (DMPs)

How Do Lenders Assess a Bad Credit Application?
1. Credit History Review
Lenders check the nature and severity of bad credit. Minor issues (e.g., phone bill defaults) may have less impact than recent mortgage arrears.
2. Deposit Size
The larger the deposit, the better your chances. A 30–40% deposit can help offset credit issues.
3. Rental Income
The expected rental income must usually cover 125–145% of the mortgage interest payments (known as Interest Coverage Ratio).
4. Experience as a Landlord
If you’ve managed properties before, this can work in your favour. However, many lenders also consider first-time landlords.

- Check your credit report with Equifax, Experian, or TransUnion
- Provide full disclosure of your credit history
- Save a larger deposit if possible
- Use a specialist lender with experience in adverse credit
