What you can afford in 2026 is the lower of two numbers: the mortgage a lender will give you (typically 4 to 4.5 times income, stress-tested), and the deposit plus stamp duty plus moving costs you have in cash. On a £50,000 income with a £25,000 deposit, that points to a property in the £225,000 to £250,000 range — but the exact figure depends on credit, existing debts, and the lender's stress rate.

The two limits that decide your budget

Every UK affordability calculation comes down to two ceilings, and you cannot exceed either:

The lender's affordability cap. Income multiples (typically 4 to 4.5x), affordability assessment under FCA MCOB 11.6, and the loan-to-value (LTV) limit on the deposit you have.
The cash you have on day one. Deposit, stamp duty, conveyancing, surveys, and moving costs all come out of savings — most cannot be added to the mortgage.

Income multiples: what lenders will lend

The standard mainstream cap is 4.5x income, with most affordability calculators landing between 4 and 4.5x for borrowers with average debt-to-income and credit. The Bank of England's December 2025 Financial Stability Report confirms the loan-to-income flow limit remains in place — no more than 15% of a lender's mortgage book may exceed 4.5x income, which is why higher multiples are rationed.

Higher multiples are available in three situations:

Professional mortgages — doctors, lawyers, accountants and similar roles can borrow 5 to 5.5x at some lenders.
High earners — incomes above £75,000 often qualify for stretched multiples.
Joint applications with strong affordability — two incomes and minimal debt can push past 4.5x.

Quick-reference: what £X salary buys

Annual income	4.5x borrowing	+ 10% deposit	Property price
£30,000	£135,000	£15,000	£150,000
£40,000	£180,000	£20,000	£200,000
£50,000	£225,000	£25,000	£250,000
£75,000	£337,500	£37,500	£375,000
£100,000 (joint)	£450,000	£50,000	£500,000

These are illustrative. The lender's full affordability model layers in childcare, season tickets, credit-card minimums, student loans, and the stress rate on top.

Deposit: the minimum and the sweet spots

The minimum deposit on a standard owner-occupier mortgage is 5%, supported by the permanent Mortgage Guarantee Scheme announced in 2025. Beyond the floor, deposit thresholds matter because each one gives access to cheaper products:

5% (95% LTV). Highest rates. First-time buyer territory.
10% (90% LTV). A noticeable rate drop.
15% (85% LTV). Another step down.
25% (75% LTV) or more. Typically the cheapest mainstream rates.

Stress testing: the silent killer of affordability

FCA MCOB 11.6 requires lenders to test that the borrower can still afford the mortgage if rates rise. A repayment that fits at today's product rate but fails the stress test will not be approved. Most lenders stress at 1% to 3% above the product rate or above their reversion rate.

This is why two borrowers on identical incomes can be offered very different loans: one has a £400/month car loan that drops their stressed affordability and shaves £30,000 off the maximum.

Cash you need beyond the deposit

The deposit is only one of the upfront costs. Budget for these on top:

Stamp Duty Land Tax — on a £400,000 home, a non-first-time buyer pays £10,000. First-time buyers pay nothing up to £300,000 of a property priced up to £500,000. See GOV.UK SDLT.
Conveyancing — typically £1,200 to £2,500 including searches and disbursements.
Survey — £400 (Level 2 HomeBuyer) to £1,000+ (Level 3 Building Survey).
Mortgage product fee — often £999, sometimes added to the loan.
Removals + utility setup — £500 to £2,000 depending on volume and distance.

Frequently asked questions

How much can I borrow on a £50,000 salary in 2026?

Most lenders cap borrowing at 4 to 4.5 times income for borrowers with average affordability and credit. On £50,000, that is roughly £200,000 to £225,000. Some lenders stretch to 5 or 5.5 times for higher earners, professional roles, or strong affordability buffers, and the FCA's loan-to-income flow limit allows up to 15% of a lender's book to exceed 4.5x.

What deposit do I need to buy in 2026?

The minimum deposit on a standard mortgage is 5% of the property price, with the Mortgage Guarantee Scheme made permanent in 2026 backing many 95% LTV products. A 10% deposit gives access to better rates, and 25% deposit (75% LTV) typically gets the lowest available rate. For a £250,000 property, that is £12,500 minimum, £25,000 for better rates, £62,500 for the cheapest tier.

Does my partner's income count?

On a joint mortgage, both incomes are assessed. The lender uses combined affordability — typically 4 to 4.5 times the joint income, less existing debt — to set the maximum loan. Both applicants are jointly and severally liable for the full mortgage, regardless of how the deposit was split.

How do lenders stress-test affordability?

Under FCA MCOB 11.6, lenders must assess whether the borrower can afford the mortgage if interest rates rise. Most lenders apply a stress rate 1 to 3 percentage points above the product rate or the lender's reversion rate. A repayment that fits at today's rate but fails the stress test will not be approved.

Do I need to budget for stamp duty separately?

Yes. Stamp Duty Land Tax is paid in cash on top of the deposit and cannot normally be added to the mortgage. From April 2025, the nil-rate band reverted to £125,000 for standard buyers and £300,000 for first-time buyers (up to a £500,000 property price). A £400,000 home costs a non-first-time buyer £10,000 in SDLT.
