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.

I cannot recommend my mortgage broker highly enough. From the very beginning of buying my property, Jordan went above and beyond to make what could have been a very stressful experience feel straightforward and manageable. He was always available to answer my questions, explained everything clearly, kept me informed throughout the process, and genuinely cared about achieving the best possible outcome for me. Nothing was ever too much trouble, and his professionalism, patience, honesty, and dedication gave me complete confidence every step of the way. His exceptional service and willingness to go far beyond what was expected made all the difference, and I am incredibly grateful for everything he did. If you're looking for a knowledgeable, trustworthy, and genuinely caring mortgage broker who truly goes the extra mile, I would recommend him without hesitation.
