How much lenders will lend
Most lenders offer around 4 to 4.5 times your annual income, and some go to 5.5 times for higher earners or small loans against a big deposit. They also test that you could afford payments if rates rose.
What affects your limit
Your credit record, regular debts such as car finance and credit cards, childcare costs and the size of your deposit all change what a lender will offer. A rule of thumb is to keep the payment under about 35% of your take-home pay.
Common questions
Does my partner’s income count?
Yes. Joint applications use both incomes, which is why there is a second income box above.
Does this include bonuses or overtime?
No. Enter your basic salary, as lenders often count only part of variable pay.
Is this a mortgage offer?
No. It is an estimate based on common income multiples. Only a lender or broker can confirm what you can borrow.
