On a £20,000 salary, you can typically borrow up to ££90,000 and buy a home worth around ££100,000 with a 10% deposit. This uses the standard 4.5x income multiple that most high street lenders apply. Some lenders go higher, and a joint mortgage with a partner significantly increases your purchasing power.
What Can You Borrow on £20,000?
| Income multiple | Maximum borrowing |
|---|---|
| 4x (cautious lenders) | £80,000 |
| 4.5x (standard) | £90,000 |
| 5x (some lenders) | £100,000 |
| 5.5x (specialist / professional lenders) | £110,000 |
The income multiple is the starting point. Lenders also conduct affordability stress tests — checking you could still afford repayments if interest rates rose to 6–7%. Your outgoings (loans, credit cards, childcare) reduce your borrowing capacity pound for pound.
What Property Can You Afford?
These figures assume you are the sole buyer on a £20,000 salary, borrowing ££90,000.
| Deposit | Property value you can reach | Monthly payment (4.5%, 25yr) |
|---|---|---|
| 5% deposit | £94,736 | £500 |
| 10% deposit | £100,000 | £500 |
| 15% deposit | £105,882 | £500 |
| 20% deposit | £112,500 | £500 |
| 25% deposit | £120,000 | £500 |
Note: deposit percentage changes the property value you can buy but not the loan amount (££90,000). A larger deposit reduces the LTV, which typically improves the interest rate you are offered.
Worked Example
Single buyer on £20,000: Takes home approximately ££1,493 per month after tax and NI. Borrowing ££90,000 at 4.5% over 25 years means a monthly payment of £500. This is 34% of take-home pay — manageable but leaving limited room for other large costs. With a 10% deposit of £10,000, they could buy a £100,000 property.
