Complex Income Mortgages

Complex Income Mortgages

You’re unique so you need a lender that understands your situation.

If your income is complex (for example, made up from different elements) or your occupation is unique, choosing the right lender is usually more difficult.

Lenders need a clear idea of how your income is made up, how regularly received, who will pay it, how long it is expected to continue at the current amount and so on.

 Kerr & Watson  will take the time to understand your income to then approach the lender that’s best placed to help you.

How We Help with Complex Income Mortgages

At Kerr & Watson, we help customers with multiple or unusual income sources find suitable mortgages. Different lenders assess income in different ways, which can significantly affect how much you can borrow.

✓ Multiple income sources – Combining employment, self-employment, rental or investment income.

✓ Bonuses, overtime and commission – Identifying lenders that consider variable earnings alongside basic salary.

✓ Specialist occupations – Helping contractors, freelancers and professionals with irregular or less conventional income structures.

✓ Investment and overseas income – Exploring lenders that consider pensions, trust income, investments or earnings in foreign currencies.

How Do Mortgage Lenders Assess Complex Income?

Mortgage lenders use different methods to calculate affordability when your earnings come from several sources.

For example, some lenders may include all of your regular bonuses or commission, while others use an average or only accept a proportion. Rental income, dividends and investment earnings can also be treated differently depending on the lender.

We compare these approaches to identify lenders whose affordability assessments best reflect your income and circumstances.

Can You Combine Multiple Income Sources for a Mortgage?

Many mortgage lenders allow applicants to combine different sources of income, although the types they accept and the amount they include can vary.

For example, you may receive a salary alongside rental income, earn money from a second job or have both employed and self-employed earnings. Lenders will consider how long you have received each income source and whether it is likely to continue.

We review your income and identify lenders that may consider your combined earnings when assessing affordability.

How Much Can You Borrow with Complex Income?

The amount you can borrow depends on which income sources a lender accepts, how they calculate your earnings and your existing financial commitments.

Some lenders may use your full regular income, while others average variable earnings or exclude certain income sources altogether. This means the borrowing amount offered can vary considerably between lenders, even when your circumstances remain the same.

We compare lender affordability assessments to establish how much you may be able to borrow before submitting a mortgage application.

I got recommended Daniel by an estate agent and her recommendation did not disappoint. Daniel and Andreea were fantastic during the whole transaction. They were both easy to reach if I had any questions or queries and never made me feel that any of my questions were silly despite being my first property purchase. They both fought my corner when we were getting tight on time to complete and found me a mortgage that worked whilst keeping communication with the lender at the forefront of their priorities until we completed as well. A fantastic first buying experience and I would definately use their services again should I be looking to move homes in the future. Thank you both!

Kerr & Watson have been absolutely outstanding in terms of knowledge, support and promptness. My case is complicated including three transactions at once and I could have not asked for a better service and support. Look nowhere else when seeking mortgage advice!

I can't recommend Kerr & Watson enough. I moved from another provider I had been using for 20+ years due to missing a purchase after multiple delays and errors. Kerr & Watson took me in as a customer and out did any expectations I had. They also taught me more about mortgages than I thought I knew, making the process easy. A great all round service by every member of the team, at every step.
