This guide explains how mortgage lenders assess self-employed income, what proof you may need, how deposits and existing commitments affect affordability, and what to do if you have only recently started trading. It also highlights practical ways to prepare a stronger self-employed mortgage application and avoid common mistakes.
Can you get a mortgage if you're self-employed?
Yes. Being self-employed doesn't stop you from getting a mortgage. The challenge is that your income can go up and down, so lenders want more evidence that it's stable and likely to continue.
Employees can show a pay slip and a contract. If you work for yourself, you'll need to prove your income in other ways, usually through tax records and accounts.
Who counts as self-employed?
Lenders generally treat these groups as self-employed:
Sole traders, who run a business as an individual.
Partners in a business partnership.
Limited company directors who own a significant share of their company.
Freelancers and contractors, who are paid per project or on a day rate.
The type of self-employment you have affects how a lender works out what you can borrow.
How do lenders assess self-employed income?
Sole traders and partners
Lenders typically look at your net profit, which is what's left after business costs. This is the figure on your tax return. Turnover (the total money coming in) isn't used because it doesn't show what you actually earn.
Many lenders average your net profit over two or three years. If your profits have risen, some will use the most recent year or the average, depending on their policy. If your profits have fallen, they may use the lower figure or the most recent year.
Limited company directors
Mortgage lenders usually look at your salary plus dividends. Some will also consider your share of the company's retained profits, which can help if you pay yourself a low salary and leave profit in the business. Not every lender does this, so it's worth asking.
Contractors and freelancers
If you work on fixed-term contracts, some lenders will assess you on your day rate. They typically multiply it by a set number of working weeks a year, often with a cautious allowance for gaps between contracts. You'll normally need a contract history and proof you've been working in the same field for a period of time.
What documents will you need?
• Lenders vary, but be ready to provide:
• SA302 forms and tax year overviews from HMRC, covering the last two or three years. These are the standard proof of self-assessed income.
• Business or company accounts, ideally prepared by a qualified accountant.
• Bank statements, both personal and business, usually for three to six months.
• Proof of ID and address.
• Proof of deposit, such as savings statements or gift letters.
• Contracts or invoices, if you're a contractor.
• Details of existing debts and regular outgoings.
Some lenders accept an accountant's certificate or reference confirming your income, which can be useful if your tax returns are not yet complete.
How much can you borrow?
Lenders work out your borrowing based on income, outgoings and the size of your deposit. As a guide, many lenders offer up to around 4 to 4.5 times your assessed annual income, though this varies by lender and circumstances.
For joint applications, they'll combine both incomes. If you're self-employed and your partner is employed, their pay slips can strengthen the application.
Your outgoings matter too. Credit card balances, loans, car finance and childcare costs all reduce what lenders are willing to offer.
How much deposit do you need?
Many self-employed borrowers get a mortgage with the same deposit as anyone else, often 5% to 10% of the property's price. A larger deposit gives you more choice and usually better rates.
If you have a shorter trading history or a patchy credit record, a bigger deposit can help offset the extra risk in the lender's eyes.
What if you've only been self-employed for a short time?
Lenders prefer two to three years of figures, but this isn't always essential. One year of accounts: Some lenders will accept a single year's figures, especially if you previously worked in the same field as an employee.
Moving from employment: If you've gone freelance in the same industry you worked in before, some lenders take that history into account.
Under a year? This is the hardest situation. A bigger deposit, a strong contract pipeline or a guarantor may help, but your options will be limited.
How to improve your chances
Keep your accounts and tax returns up to date
File your self-assessment on time and keep proper records. Having your SA302s and tax year overviews ready speeds things up.
Think carefully about how you pay yourself
If you're a company director, reducing your taxable income to save tax can also reduce what lenders are willing to lend. If a mortgage is on the horizon, speak to your accountant well in advance about the balance.
Check and tidy your credit file
Look at your credit report for errors. Pay bills on time, keep credit card use low and register on the electoral roll.
Reduce existing debts
Paying down credit cards and loans improves affordability and can increase your borrowing power.
Keep personal and business finances separate
A clean, separate business bank account makes it easier for lenders to see your income clearly.
Avoid making lots of applications
Every application can leave a mark on your credit file. Get advice first, then apply to lenders that suit your situation.
Consider a broker
A broker who understands self-employed lending can match you with lenders whose criteria fit your circumstances and present your case properly.
Common mistakes to avoid
Applying before you have enough trading history, when waiting a few months would help.
Relying on turnover instead of net profit when working out affordability.
Having undeclared income that can't be proven, as lenders can only use income that appears in your tax records.
Taking on new credit or making big purchases just before applying.
Choosing a lender without checking its self-employed criteria.
Risks to be aware of
Variable income can make mortgage payments harder to manage in a quiet period. Before you commit, think about whether you could cover repayments if your income dropped, and whether you have an emergency fund. It may also be worth looking into income protection insurance.
Your home may be repossessed if you do not keep up repayments on your mortgage.
