How much mortgage can you get on £40,000?
Most high-street lenders use an income multiple to cap how much they'll lend. The standard range in 2026 is 4 to 4.5 times your annual income, though some lenders will go up to 5× for applicants with strong credit profiles, low outgoings, and a larger deposit. On a £40,000 salary this translates to a maximum of roughly £200,000.
Income multiples are a starting point, not a guarantee. Lenders also run an affordability assessment that looks at your monthly outgoings, existing loans, credit cards, car finance, childcare costs, and estimated living expenses. A high multiple is only possible if your disposable income comfortably covers the mortgage repayments after all other commitments.
How the deposit affects what you can buy
The deposit size matters for two reasons: it determines the loan-to-value (LTV) ratio (lower LTV = better rates) and it affects the total property price you can afford.
- 5% deposit, The minimum for most residential mortgages. Rates will be higher and lenders may be more restrictive on income multiples.
- 10–15%, Access to a much wider range of products with meaningfully lower rates compared to 95% LTV.
- 20%+, Near the best rates available. Each 5% step above 20% typically unlocks a slightly lower rate but with diminishing returns.
First-time buyers should consider the Lifetime ISA, you can save up to £4,000 per year and receive a 25% government bonus (up to £1,000/year) towards a deposit.
What affects lender decisions in 2026?
- Credit score, Missed payments, defaults or high utilisation will reduce both the multiple offered and the rates available.
- Employment type, Employed applicants are generally assessed more favourably than self-employed. Lenders typically require 2–3 years of self-employed accounts.
- Existing debt, Student loans, car finance and credit card balances all reduce what lenders will offer.
- Number of applicants, Applying jointly with a partner adds both incomes to the calculation. Two applicants on £40,000 could borrow £320,000–£360,000.
- Stress testing, Lenders check you could still afford the repayments if rates rose by 3%, in line with FCA guidance.
How stamp duty affects affordability
Don't forget stamp duty land tax (SDLT). From April 2025 the nil-rate threshold for non-first-time buyers returned to £250,000. First-time buyers pay no SDLT on the first £300,000 of a property costing up to £500,000. Use our Stamp Duty Calculator to see exactly what you'd owe on any property price.

Frequently asked questions
Can I definitely get a mortgage on a £40,000 salary?
The figures shown are estimates based on standard income multiples. A lender's actual offer depends on your full financial picture: credit history, existing debts, monthly outgoings, and the type of property. Use these numbers as a starting point, then speak to a mortgage broker or use a lender's affordability tool to get a decision in principle.
What deposit do I need for a mortgage on £40,000?
The minimum deposit for most residential mortgages is 5% of the property price. However, a 10% deposit unlocks significantly better rates, and 15–20% gives access to the most competitive products. First-time buyers can use a Lifetime ISA to save up to £4,000 per year and receive a 25% government bonus (up to £1,000/year) toward their deposit.
Can I borrow more with a joint mortgage?
Yes. With a joint mortgage both incomes are combined for affordability purposes. Two applicants each earning £40,000 could borrow £320,000 to £360,000 at 4–4.5× the combined income. Joint applications also typically benefit from a larger combined deposit, which can unlock better interest rates.
Does being self-employed affect how much I can borrow?
Self-employed applicants are assessed differently. Most lenders require at least two to three years of filed accounts or tax returns and base their offer on your average net profit (or salary plus dividends if you trade via a limited company), not your turnover. Some specialist lenders accept one year of accounts. A whole-of-market broker can identify the most suitable lenders for self-employed borrowers.
What is mortgage stress testing?
Since 2015 the FCA has required lenders to check that borrowers could still afford repayments if the interest rate rose significantly. In practice this means lenders verify affordability at a rate roughly 3 percentage points above the reversion (standard variable) rate. Passing the stress test is a requirement to borrow at the income multiple shown, not an optional hurdle.
How does a mortgage in principle work?
A mortgage in principle (MIP), also called an agreement in principle (AIP) or decision in principle (DIP), is a conditional offer from a lender stating how much they would be willing to lend, subject to full underwriting. Estate agents often ask for one before accepting offers. Getting an MIP leaves a soft credit footprint with most lenders and is free. It is not a guarantee of a mortgage offer.
