Will a lender agree?
Lenders usually test the rent against interest at a higher “stress” rate, here 7%. Rent covers it by 125% (basic-rate taxpayers and companies): no; by 145% (higher-rate taxpayers): no. The rent supports a loan of about £323,246 or £278,660. Lenders differ.
- The rent may not pass a typical lender stress test: lenders often want rent to cover interest at 7% by 125%, which caps the loan near £323,246.
All figures are before income tax. Individual landlords cannot deduct mortgage interest in full (they get a 20% tax credit instead), so higher-rate taxpayers pay tax on more than their cash flow. This is a calculator, not financial advice. Read the guide
