How much mortgage can I get on a £45,000 salary?

Most UK lenders will consider lending around four to four and a half times your income, so on a £45,000 salary that is roughly £180,000 to £202,500. Some lenders go higher in certain cases, and your outgoings, debts and credit history can bring it down. Borrowing it is one thing — affording it every month is another.

What would the monthly payments be?

On a repayment mortgage over 25 years at an illustrative 4.5% rate:

• £180,000 (4 × income): about £1,001 a month
• £202,500 (4.5 × income): about £1,126 a month

Your real rate depends on the deal, your deposit and your credit history, so treat these as a guide.

What do lenders look at?

• Your income — and how much of any bonus or overtime they will count
• Your regular outgoings, including childcare and other commitments
• Debts such as car finance, loans and credit cards
• Your credit history
• The size of your deposit

What does the home cost on top of the mortgage?

Council tax (rates in Northern Ireland), energy, water, broadband and insurance often add £400 or more a month. Then there is upkeep: a common rule of thumb is about 1% of the property's value a year — around £190 a month on a £225,000 home.
