Underwriting

The process a lender uses to assess whether you meet their criteria for a mortgage, including checks on your income, credit history and the property.

Underwriting is the detailed assessment a lender carries out once you submit a full mortgage application. An underwriter reviews your financial information, employment status, credit history, existing debts and the property you intend to buy to decide whether the lender is prepared to offer you a mortgage and on what terms.

The underwriting process can be partly automated and partly manual. Many lenders use automated systems to perform initial checks, but more complex cases are referred to a human underwriter for a decision. The process typically takes between a few days and several weeks, depending on the lender and the complexity of your application.

During underwriting, the lender may ask for additional documents such as bank statements, payslips, or explanations of unusual transactions. Responding to these requests promptly helps avoid delays. The outcome of underwriting is either approval (leading to a mortgage offer), a request for further information, or a decline.

Example

After you submit your mortgage application, the lender's underwriter notices a large cash deposit in your bank statement. They ask you to provide evidence of where the money came from as part of their anti-money-laundering checks. Once you supply the documentation, they approve the application.

Frequently Asked Questions

How long does mortgage underwriting take?

It varies by lender and complexity. Straightforward applications can be underwritten within a few days. More complex cases, such as self-employed applicants or those with adverse credit, may take two to four weeks or longer.

Can I speed up the underwriting process?

Yes. Have all your documents ready before you apply, respond to any requests for additional information promptly, and make sure your application is accurate and complete. Using a broker who knows the lender's requirements can also help.

What happens if underwriting declines my application?

If your application is declined, the lender should explain why. Common reasons include insufficient income, credit issues, or problems with the property. A mortgage broker can help you understand what went wrong and find an alternative lender whose criteria you are more likely to meet.
