## Mortgage Overview
A *BTL mortgage bad credit 10 year fixed* is a buy-to-let mortgage product that locks in your interest rate for a decade, regardless of wider economic fluctuations. These mortgages are designed for landlords who want long-term payment certainty while renting out residential properties.
Unlike standard residential mortgages, BTL products are assessed primarily on the rental income potential of the property rather than the applicant’s personal income. However, personal finances still play a role—especially for applicants with adverse credit.
There are several types of BTL mortgages:
– **Fixed-rate:** Interest rate remains constant for the term (e.g., 10 years)
– **Variable-rate:** Linked to lender’s standard variable rate (SVR)
– **Tracker-rate:** Follows the Bank of England base rate plus a margin
A 10-year fixed rate is ideal for:
– **First-time landlords** seeking predictable costs
– **Portfolio landlords** wanting to stabilise cash flow
– **Limited companies** looking for long-term investment certainty
In 2025, lender appetite for bad credit BTL mortgages is growing, with more specialist lenders entering the market. However, stricter stress testing and affordability rules apply, especially under the Financial Conduct Authority’s (FCA) responsible lending guidelines.
