Key Points

  • Lenders will look at what you own, what you owe, your living costs, and any other regular payments you make.

  • At least one borrower needs a credit score of 600 or higher to qualify for a mortgage.

  • When calculating if you can afford your mortgage, lenders use either your mortgage interest rate plus 2%, or 5.25%, whichever is higher.
