Getting a mortgage when you are self-employed is entirely achievable, but it does require more preparation than a standard employed application. Lenders need to be confident that your income is real, consistent, and sustainable, and demonstrating that takes a bit more legwork. Here is a practical guide to giving yourself the best possible chance.
Start preparing early
Ideally, you should start thinking about your mortgage at least a year before you plan to apply, and two years is better. Lenders typically want to see two to three years of accounts or SA302 tax calculation forms from HMRC, along with bank statements. Getting these in order well in advance means you are not scrambling when the time comes.
If you use an accountant, make sure your accounts are filed on time each year and that they accurately reflect your income. Lenders look closely at the figures, and any inconsistencies or late filings can raise questions.
Show consistent income
Lenders feel most comfortable when they can see a stable pattern of income over time. If your earnings have been growing steadily year on year, that tells a positive story. If there have been significant fluctuations, be prepared to explain them. Some lenders will use an average of your last two or three years of income, while others will use the most recent year, so the way your income trends matters.
Build a strong credit profile
A good credit score matters for any mortgage application, but it carries extra weight when your income is less straightforward to verify. Pay all bills and any existing credit on time, keep credit card balances well below their limits, and avoid applying for new credit in the months leading up to your mortgage application.
Check your credit report in advance and address any errors you find. The three main agencies in the UK are Experian, Equifax, and TransUnion, and you can check with each for free.
Save as much deposit as you can
A larger deposit reduces the lender’s risk and improves your access to better mortgage rates. Aim for at least 10% to 20% of the property value, with 25% or more putting you in the strongest position. It also demonstrates financial discipline, which works in your favour.
Be thoughtful about business expenses
Claiming legitimate business expenses reduces your taxable income, which is a sensible thing to do from a tax perspective. However, it also reduces the income figure lenders see. In the years leading up to a mortgage application, it is worth having a conversation with your accountant about the right balance between minimising your tax bill and presenting a strong income figure to lenders.
Consider specialist lenders
Not all lenders assess self-employed applications in the same way. High street lenders sometimes apply more rigid criteria, while specialist lenders who work regularly with self-employed borrowers can be more flexible in how they interpret your income. A mortgage adviser with experience in self-employed cases will know which lenders are likely to look most favourably on your application.
Work with a mortgage adviser
This is perhaps the most important step. An experienced mortgage adviser understands the landscape for self-employed borrowers, knows which lenders are most accommodating, and can help you present your application in the strongest possible way. They can also identify potential issues before you apply and help you address them in advance.
