What Is a Buy to Let Mortgage?

BTL mortgages finance rental property. Lenders assess affordability using expected rent rather than your personal income.

Key features

  • Rental coverage: rent must typically cover 125–145% of mortgage interest (stress‑tested).
  • Higher deposits: 20–40% is common.
  • Interest‑only is popular among landlords.
  • Fees/rates usually higher than residential.

Who can get one?

Often requires homeownership, clean credit, a minimum personal income (e.g., ~£25k), and sufficient deposit.

Use cases

Long‑term investment, portfolio growth, potential tax efficiency via limited companies, and retirement income planning.

Example

£200k property; £50k deposit; £150k interest‑only mortgage. Rent £900/m. If stressed at 145% coverage, rent target ~£725 for a £500/m interest cost—met in this case.

Benefits

Portfolio leverage, scalable borrowing, flexible repayment structures.

Risks

Void periods, rate rises, price volatility, regulation/tax changes affecting returns.
