Property prices you can afford (4.5× scenario, £135,000 mortgage)
| Deposit | Property price | LTV |
|---|---|---|
| £10,000 deposit | £145,000 | 93% LTV |
| £20,000 deposit | £155,000 | 87% LTV |
| £50,000 deposit | £185,000 | 73% LTV |
| £100,000 deposit | £235,000 | 57% LTV |
LTV = Loan-to-Value. Lower LTV = better mortgage rates. 90% LTV (10% deposit) unlocks standard rates; 85% or below gets the best deals.

A 1 percentage point rise in rates adds roughly £79 per month to your repayment. Fix your rate for 2–5 years to protect against rises.
Affordability context — £30,000 take-home
How much can you borrow on a £30,000 salary in 2025?
UK mortgage lenders use an income multiple to determine the maximum loan size. The standard multiple is 4 to 4.5 times gross annual salary, meaning a £30,000 income supports a mortgage of £120,000 to £135,000. A handful of lenders — typically for high earners, professionals, or those with very low outgoings — will stretch to 5 times income (£150,000).
How lenders assess affordability
Beyond the income multiple, every lender runs a full affordability assessment that considers:
- Monthly outgoings: credit card debt, car finance, personal loans, childcare costs, subscriptions, and regular bills all reduce your borrowing capacity.
- Credit score: a strong credit history gives access to more competitive rates and higher income multiples. Check your report at Experian, Equifax, or TransUnion before applying.
- Deposit size: a larger deposit reduces the lender's risk (lower LTV), unlocking better rates and often higher income multiples.
- Employment type: permanent employees are assessed on salary; self-employed applicants typically need 2–3 years of accounts. Contractors may use day rate × 48 weeks.
- Stress testing: lenders must check you can afford repayments if rates rise by 3 percentage points above the reversion rate.
How to improve your mortgage affordability
- Pay down existing debts (credit cards, personal loans) before applying — these directly reduce what lenders will offer.
- Avoid new credit applications in the 6 months before your mortgage application.
- Save a larger deposit to move from 95% LTV to 90% or 85% — rates improve meaningfully at each threshold.
- Consider whether pension contributions are salary-sacrificed — some lenders use your gross salary before sacrifice for affordability calculations.
- If you are close to a tax band boundary (e.g. just above £50,270), a pension contribution that brings your taxable income down can sometimes improve your take-home position.
- Joint mortgages use combined income, so a partner's salary can significantly increase what you can borrow.
First-time buyer options
First-time buyers in England can access the Mortgage Guarantee Scheme (5% deposit on properties up to £600,000) and the Lifetime ISA (25% government bonus on savings up to £4,000/year, usable for a first home). In Scotland, the Help to Buy (Scotland) scheme provides equity loans for new-build properties.
Frequently asked questions
How much can I borrow on a £30,000 salary?
On a £30,000 salary, most UK mortgage lenders will offer between £120,000 (4× income) and £135,000 (4.5× income). Some specialist lenders offer up to £150,000 (5× income) for high earners or those in professional occupations. Actual amounts depend on your credit score, monthly outgoings, and the lender's affordability checks.
What is the monthly payment on a £135,000 mortgage?
At 5% interest over 25 years, a £135,000 mortgage costs £789 per month. At 4.5% the monthly payment falls to £750; at 5.5% it rises to £829. Over the full 25-year term at 5%, total repayments are £236,700.
Is a £135,000 mortgage affordable on a £30,000 take-home pay?
Your take-home pay on £30,000 gross is approximately £2,093/month. A £135,000 mortgage at 5% costs £789/month — that is 38% of your net monthly income. Financial advisors recommend keeping mortgage payments below 35% of net income; above 40% is considered financially stretched.
How do mortgage lenders calculate how much I can borrow?
Most UK lenders use an income multiplier of 4 to 4.5 times annual salary for single applicants. Joint applicants use combined income. Some lenders offer 5× or even 5.5× for high earners or those with strong credit history. Affordability checks also consider monthly outgoings, credit commitments, and living costs.
How much deposit do I need for a mortgage?
Minimum is typically 5% of the property value (95% LTV). A 10% deposit (90% LTV) gives access to better rates. 15–20% deposits get the best rates. First-time buyers in England can use the mortgage guarantee scheme (5% deposit) or Lifetime ISA for deposit savings.
What is a good affordability ratio for a mortgage?
Most financial advisors suggest mortgage repayments should not exceed 28–35% of gross income, or 35–40% of net (take-home) income. Above 40% of net income creates financial vulnerability. Use the figures on this page to see where your repayments fall.
