How Much Do You Need to Earn for a £350,000 Mortgage?

If you’re asking how much do you need to earn for a £350000 mortgage, you’re likely trying to understand whether your income can realistically support this level of borrowing. While it’s tempting to look for a single salary figure, mortgage lenders assess affordability using your wider financial picture — not income alone.

This guide explains the typical income needed for a £350,000 mortgage, how lenders calculate affordability, and what can increase or limit how much you’re able to borrow.


Quick Answer: How Much Salary Is Usually Needed?

Most lenders work to an income multiple of around 4 to 4.5 times annual income.

Based on this:

  • £350,000 ÷ 4.5 = around £78,000
  • £350,000 ÷ 4 = around £87,500

In practical terms, most borrowers will need an income between £78,000 and £88,000 to borrow £350,000, assuming standard living costs and no significant financial commitments.

This is a guideline rather than a guarantee — affordability checks ultimately determine the final figure.


How Lenders Calculate Mortgage Affordability

Income multiples provide a starting point, but affordability testing determines whether monthly repayments are sustainable over the long term.

Lenders typically assess:

  • Your income (salary, bonuses, overtime, or self-employed earnings)
  • Regular outgoings such as loans, credit cards, childcare, and maintenance
  • Existing financial commitments
  • The mortgage term you choose
  • Whether repayments remain affordable if interest rates rise

Even with sufficient income, high monthly outgoings can reduce what a lender is willing to offer.


Income Requirements for Different Buyer Types

Single applicants

If you’re applying on your own, lenders rely entirely on one income. In most cases, a single applicant will still need around £78,000–£88,000, with stable employment and limited unsecured debt.

Single-income applications are assessed more cautiously, which is why lender criteria can make a meaningful difference. This is explored further in our guide on getting a mortgage on one income.

Joint applicants

Joint applications allow incomes to be combined, improving affordability.

For example:

  • £45,000 + £43,000 = £88,000 combined income

This can make borrowing £350,000 more achievable than relying on one income alone.


What Are the Monthly Repayments on a £350,000 Mortgage?

Monthly repayments depend on your interest rate and mortgage term.

As a rough guide:

  • Over 25 years: typically around £1,750–£2,050 per month
  • Over 30 years: lower monthly payments, but higher total interest
  • Shorter terms: higher monthly cost, but less interest paid overall

Lenders stress-test these payments to ensure they remain affordable if interest rates increase.


How Your Deposit Affects the Income You Need

A larger deposit can significantly improve affordability.

Although the mortgage amount remains £350,000, a higher deposit can:

  • Reduce lender risk
  • Unlock more competitive interest rates
  • Make affordability calculations more flexible

Typical scenarios include:

  • 10% deposit: standard lending criteria
  • 15–20% deposit: wider lender choice and easier affordability

If your deposit is smaller, lenders may expect a higher income to offset the increased risk.


Can You Get a £350,000 Mortgage With Bad Credit?

Yes — it’s possible, but criteria are usually stricter.

Lenders will consider:

  • How recent the credit issues were
  • Whether debts are settled
  • How finances have been managed since

Missed payments, defaults, or historic CCJs don’t automatically prevent a £350,000 mortgage, but a larger deposit or specialist lender may be required.


What If You’re Self-Employed?

Self-employed applicants can qualify for a £350,000 mortgage, but income is assessed differently.

Most lenders look at:

  • Two years of accounts or tax calculations
  • Averaged income over recent years
  • Salary and dividends for limited company directors

Some lenders are more flexible where income is stable or increasing. This is covered further in our guide for self-employed first-time buyers.


What Can Reduce How Much You’re Allowed to Borrow?

Even if your income appears sufficient, lenders may reduce borrowing due to:

  • Personal loans or car finance
  • Credit card balances
  • Childcare costs
  • Maintenance payments
  • Regular overdraft use

Bank statements play an important role in this assessment, as they show how income is actually managed month to month.


How to Improve Your Chances of Affording a £350,000 Mortgage

Improving affordability is often more effective than increasing income alone.

Helpful steps include:

  • Reducing unsecured debts
  • Avoiding overdraft reliance
  • Avoiding new credit applications before applying
  • Keeping spending consistent
  • Saving a larger deposit where possible

Small changes can have a meaningful impact on lender calculations.


What If Your Bank Says You Don’t Earn Enough?

A decline from your bank doesn’t necessarily mean a £350,000 mortgage isn’t achievable.

High street lenders often apply stricter affordability models. Other lenders may:

  • Accept variable or multiple income streams
  • Take a more flexible view of credit history
  • Use different affordability stress tests

Choosing the right lender can significantly affect the outcome.


Key Takeaways

  • Most borrowers need £78,000–£88,000 income for a £350,000 mortgage
  • Income multiples are only part of the assessment
  • Monthly outgoings strongly influence affordability
  • Larger deposits improve lender choice and interest rates
