Fundamental guides for self-employed borrowers

Calculating your affordability is a great start, but lenders look at self-employed income in many different ways. To get a more accurate picture, choose the guide below that best describes how you work.

Frequently asked questions

The amount you could borrow will depend on the lender used. This is because each lender has their own way of assessing and calculating your affordability. A lender will look at your income and expenses, which will help them determine what you can comfortably afford.

When you are self-employed some lenders will look at your latest year’s tax return to help them decide. Although, there are others that will look at the past two to three years and then take an average.

As a general rule the larger your deposit and greater your income, the more you can borrow. However, if you are seen as a lending risk because of bad credit, it could reduce your borrowing capabilities.

To give a rough guide, you could borrow up to 4.5x your annual income. This is very similar to what someone in conventional employment could borrow. If you want to discuss your mortgage options, reach out today.

Again, as with your borrowing capabilities, your deposit amount will depend on the lender.

Nowadays you’ll usually need a minimum of 5–10% of the property’s market value. Although, the average deposit in the UK is closer to 20%.

This is due to the fact that a larger deposit allows you to access more favourable deals with better rates, saving you money in the long run due to the saving on interest.

To read more about deposits, you can read our complete self-employed guide.

Lenders usually require you to have been self-employed for at least a year, as they need to look at your accounts during their affordability assessment. If this is the case, they will also assess your employment before you turned self-employed.

Keep in mind that certain lenders may require 2 or 3 years’ worth of accounts.

However, just because you have only been trading for a year doesn’t mean you could borrow less. The income you receive will play a large part in what you could borrow.

⭐⭐⭐⭐⭐ Outstanding service from start to finish! I cannot recommend Mark Gardiner highly enough as a mortgage advisor. From our very first conversation, he took the time to fully understand my financial situation, goals, and concerns, and explained every step of the process in clear, simple terms—no confusing jargon at all. Mark went above and beyond to find the best possible mortgage deal tailored exactly to my needs, comparing options thoroughly and always keeping me updated with regular progress reports. He was incredibly responsive, patient, and proactive throughout, anticipating potential issues and resolving them quickly to keep everything on track. Thanks to his expertise, attention to detail, and genuine commitment to getting the best outcome for me, what could have been a stressful process felt smooth and straightforward. I felt completely confident and well-supported at every stage. If you’re looking for a knowledgeable, trustworthy, and dedicated mortgage advisor, Mark is the person to choose. I would not hesitate to use his services again or recommend him to friends and family.I will definitely use him in the future too. Great work

I couldn't recommend Needham Mortgage Centre highly enough. From the start to the end of buying our first home, Jordan provided us with clear guidance and exceptionally prompt responses to any queries we had. For what we expected to be a stressful and confusing part of buying our first house, the Needham Mortgage Centre couldn't have done any more to make it understandable and stress-free.

Mark provided friends and top tier service, he found us a mortgage that worked really well for us, and talked us through all the options so we could make informed decisions. He supported us throughout the entire process with getting our mortgage in principle when looking to buy, right up until completion, we look forward to returning to his service when our mortgage needs renewing. He also put us in touch with other members of the team who helped us with all the different types of insurances, which made the process of buying as a first time buyer so smooth. Thank you for all your support Mark and the rest of the team.
