Buy-to-let mortgages explained

Repayment mortgage: Each monthly payment covers interest plus a portion of the loan. By the end of the term, the full loan is repaid and you own the property outright. Monthly payments are higher but total costs are lower.

Interest-only mortgage: You only pay interest each month. The original loan amount must be repaid in full at the end of the term (typically by selling the property or refinancing). Monthly payments are lower but you pay more interest overall and still owe the full loan.

Most buy-to-let lenders require a minimum 25% deposit (75% LTV). Interest rates for buy-to-let are typically higher than residential mortgages. Lenders also assess whether your expected rental income covers at least 125-145% of the mortgage payments.
