What Lenders Consider When Reviewing Mortgage Applications

Jul 2026

Whether you’re a first-time buyer, home mover or looking for a buy-to-let property, the mortgage application process is an important milestone in your journey. Understanding what mortgage lenders consider may help you prepare your application and avoid unnecessary delays.

Here are seven factors that mortgage lenders commonly assess during the mortgage application process.

Income and Employment Status 

Income and employment stability are important parts of the mortgage application process, as lenders need to assess whether the repayments you would be committing to are affordable.

The questions a lender is likely to ask about your employment status include how long you have been employed and whether any probationary periods have been completed.

If you’re self-employed, you may need to provide two years of accounts and details of your income as part of your application.

As well as confirming that you have a reliable income, the lender will assess whether your income is sufficient to support the proposed mortgage repayments. Lenders will usually request documentation to verify your income, such as payslips, bank statements, P60s or tax documents for self-employed applicants.

How much you may be able to borrow will depend on your individual circumstances and the lender’s affordability assessment.

Affordability Assessment

Income is only one part of the picture. Mortgage lenders also assess affordability by looking at your regular financial commitments and household spending.

Factors commonly reviewed include:

  • Existing loans and credit agreements
  • Credit card balances
  • Household bills
  • Childcare costs
  • Dependants
  • Day-to-day living expenses

Many lenders also carry out affordability stress tests to assess whether you could continue to afford your mortgage repayments if interest rates were to increase in the future.

Credit History

Your credit history helps mortgage lenders understand how you have managed borrowing in the past.

A strong credit history may improve the range of mortgage products available to you, although approval and interest rates will depend on a range of factors, including your individual circumstances and the lender’s criteria. A poor credit history may reduce the options available or affect the terms offered.

A strong credit history does not guarantee approval, but it may provide lenders with greater confidence in your ability to manage future repayments.

Before applying, it can be worthwhile checking your credit report to ensure the information recorded is accurate and up to date.

Deposit

When assessing your deposit, mortgage lenders will typically consider both the size of the deposit relative to the property’s value and the source of the funds. A larger deposit reduces the Loan-to-Value (LTV) ratio and may improve the range of mortgage products available, depending on your individual circumstances and the lender’s criteria.

Property Assessment

Once your mortgage application has been submitted, the lender will usually arrange a valuation of the property. The purpose of the valuation is to assess whether the property provides suitable security for the mortgage and whether its value supports the amount being borrowed.

Existing Financial Commitments

Mortgage lenders will review your existing financial commitments and previous borrowing when assessing affordability.

These may include:

  • Personal loans
  • Car finance agreements
  • Credit cards
  • Student loans
  • Other mortgage commitments

Existing commitments can affect affordability because they influence how much disposable income remains available for mortgage repayments.

Identity and Verification Checks

As part of regulatory and anti-fraud requirements, mortgage lenders must verify your identity and address.

You may be asked to provide:

  • Passport or driving licence
  • Proof of address
  • Bank statements
  • Evidence showing the source of your deposit

Providing documents promptly may help keep the mortgage application process moving smoothly.

Talk to a Mortgage Adviser

If you’re preparing for a mortgage application, speaking with a mortgage adviser can help you understand how the process works and discuss the mortgage options that may be available based on your individual circumstances.
