Chapter 1: How Much Can You Borrow?
The first question most buyers have — and the answer might surprise you.
The income multiple rule
Most lenders will offer between 4 and 4.5 times your gross annual income. If you're buying with a
partner, both incomes typically count.
Annual Income At 4x and At 4.5x
£25,000 £100,000 £112,500
£35,000 £140,000 £157,500
£50,000 £200,000 £225,000
£60,000 (joint) £240,000 £270,000
These are rough guides — your actual borrowing limit depends on your outgoings, credit history,
and the specific lender. A broker can give you an accurate figure quickly.
Your deposit matters too -
The size of your deposit directly affects the interest rate you're offered. Here's a simple
breakdown:
• 5–9% deposit: You can get a mortgage, but rates will be higher
• 10% deposit: Significantly more deals available
• 15–20%+ deposit: Access to the best rates on the market
📌📌 Quick tip
Even a small improvement in your deposit percentage can save you thousands over the life
of your mortgage. It's worth waiting an extra few months if it moves you into a better
bracket.
