Eight Mortgage Underwriter interview questions, and what the interviewer is thinking

1. How do you assess whether a residential mortgage applicant can afford the loan?

Why they ask: To test the core of the underwriter's job: responsible lending and affordability.

Why they ask: To check you appreciate the balance between supporting lending and managing risk.

3. How would you assess the income of a self-employed or limited company director applicant?

Why they ask: To test your ability to assess non-standard income accurately.

4. You notice an application's payslips show a salary that does not match the credits in the bank statements, and the broker is pressing for a quick decision. What do you do?

Why they ask: To test your integrity and willingness to resist pressure when you suspect fraud.

5. How would you treat adverse credit, such as missed payments, defaults, CCJs or an IVA, in an application?

Why they ask: To check you can apply credit policy sensibly and consistently.

6. What property features would concern you as an underwriter, and how would you decide if a property is acceptable security?

Why they ask: To test your ability to assess the property, not just the borrower.

7. Tell me about a time you declined or referred a case despite pressure from a colleague, broker or manager.

Why they ask: To see whether you can make independent decisions under pressure and communicate them professionally.

8. How does underwriting buy-to-let differ from residential, and what is an interest coverage ratio?

Why they ask: To test your knowledge of specialist lending standards you may meet as a mid-level underwriter.

A sample answer to question 1

How do you assess whether a residential mortgage applicant can afford the loan?

Affordability must follow MCOB 11.6, so I start by verifying income from evidence such as payslips, P60s or SA302s, and working out what is genuinely sustainable, treating bonuses, overtime and commission as the lender's policy allows. Then I establish committed expenditure from the credit file and bank statements: loans, credit card payments, car finance, childcare and maintenance. I add basic essential and quality-of-life spending, using either the applicant's declared figures cross-checked to statements or the lender's expenditure model. The remaining income is tested against the mortgage payment at the product rate and at a higher stressed rate, since customers must be able to cope with reasonable interest rate rises. I would also look at the loan to income multiple, bearing in mind the Financial Policy Committee's limit on the share of high LTI lending. Finally I consider future changes such as retirement, a fixed-term contract ending or a maternity leave. If affordability is marginal I would look at the term, the product or a deposit before deciding.

Common mistake to avoid: Relying only on a salary multiple; ignoring committed spending
