What If You Have Overtime or Bonuses?
If your base salary is £20,000 but you regularly earn overtime or receive bonuses, some lenders will include a portion of that extra income in their affordability calculation. Typically they accept 50% to 100% of regular overtime and 25% to 60% of annual bonuses. Even a small amount of additional income can push your borrowing up by several thousand pounds, so it is worth checking lenders who are more generous with variable pay.
What Could You Buy?
A larger deposit can unlock higher income multiples at some lenders. At 25% deposit, several lenders in the table above would offer even more. Use our calculator to check your exact figure with your specific deposit.
On a £20k salary, shared ownership is well worth exploring. You buy a share of the property (typically 25% to 75%) and pay rent on the rest, which means you need a much smaller mortgage and deposit. Many housing associations have properties specifically aimed at first-time buyers earning under £80,000.
What Reduces Your Borrowing?
Lenders subtract your existing financial commitments before deciding how much to lend. On a £20k salary, even small debts have a noticeable impact:
- Credit card balances — lenders assume a minimum monthly payment, often 3% of the limit, even if you pay in full each month.
- Car finance — a £200/month car payment could reduce your maximum mortgage by £10,000 to £15,000.
- Student loans — Plan 2 repayments are deducted from your gross income before affordability is calculated. On £20k you may be below the threshold, which is helpful.
Buying with a Partner
If your partner also earns £20,000, your joint income of £40,000 could unlock borrowing of £160,000 to £232,000. That dramatically increases the properties within reach. Even if your partner earns less, adding a second income almost always improves the amount lenders are willing to offer.
Some lenders apply the income multiple to the higher earner and add a portion of the second income, while others multiply the combined figure. Checking multiple lenders helps you find the most favourable approach.
