Self-Employed Mortgage First-Time Buyer

How much can I borrow for a mortgage if I’m self-employed and a first-time buyer?

This is based on your provable income. For a self-employed first-time buyer, most banks will lend you around 4.5 to 5.5 times your income.

It will vary on a case-by-case basis. The more you earn, obviously, the more you can borrow. Often lenders will have a threshold where if you earn more than £50,000, for example, you can access higher income multiples – even up to 5.5 times.

For those that are self-employed and paid through the CIS scheme, we can even use gross income, which can increase the level of borrowing massively. There are lots of options for self-employed first-time buyers.

How is a mortgage calculated for a self-employed first-time buyer in the UK?

If you’re a sole trader or in a partnership, lenders use your net profit after your expenses. They’ll ask to see a document called an SA302, which is sometimes known as a tax calculation.

It’s not the full download of your self-assessment, because that’s about 20 pages long. It’s the 100% complete finalised SA302 tax calculation. Lenders use that to see your net profit after expenses.

Lots of self-employed people can be very tax-efficient, but when it comes to getting a mortgage it’s a good idea to plan ahead. Assess how hard you need to be working to get enough profit for the mortgage.

Most mortgage lenders usually average the last two years unless your most recent year is higher, in which case we might be able to use that year alone. If the most recent year is lower, however, sometimes the lender ignores the previous year as there’s a downward trend. There are different permutations to consider there.

There are two different ways to assess a limited company director. The first one is using your SA302 or your tax calculation, using the salary that you draw out plus any dividends in the last year. Mortgage lenders might look at the latest year or take an average of two.

However, an increasing number of mortgage lenders now look at retained profits in the company. You might only withdraw what you need to live off, and leave a lot of profit in the business. Some lenders can use the salary you draw plus that profit left in the business for the year – and that can really boost the amount you can borrow.

What documents do I need to prove my income?

In terms of proving your income, your bank statements are really important. For a self-employed first-time buyer running a business, it’s not unusual for a bank to want to look through your bank accounts to see that there’s sufficient money flowing through.

Don’t forget, if you’re submitting a tax return, it could be almost 18 months old by the time a lender sees it. Most lenders would accept a tax return up until October of the following year.

So banks want to check the turnover on your statements to make sure you’re still consistently earning that income. You may need up to six months’ bank statements.

Next we need ID – normally government issued photo ID. That’s a driving licence, a passport or even a shotgun licence for some lenders. We also need address identification – normally a bank statement, credit card statement or council tax bill. Then, obviously, proof of your deposit going back over time to show how you’ve built up the funds.

How can I improve my chances of getting a mortgage as a self-employed first-time buyer?

Get all your ducks in a row – gather your documents and put your accountant on notice for what you’re going to need. Order or download your bank statements.

Then check your credit file. If you don’t know what you’re looking at, because they can be quite complicated, run it past your mortgage broker. Make sure it’s accurate. You might find you’ve still got your bank account registered to mum and dad’s house – get all your addresses up to date.

Avoid big, unexplained transfers coming in and out of your bank account, because any mortgage broker, bank or solicitor will ask what they are. Don’t take out any new credit agreements, loans or spend a lot on a credit card just before applying, as it doesn’t look good.

Of course, the best way to improve your chance of getting approved is to use a mortgage broker who understands self-employed cases inside out. That makes a massive difference.

How do I apply for a mortgage as a self-employed first-time buyer? How can a mortgage broker help?

A broker’s going to do all the heavy lifting. We’ll look at your accounts and work out which lenders will use the income in the most generous way. We’ll find the deals for you based on your individual circumstances. We check the affordability, handle the documents, and package the case together for your situation.

For a lot of mortgage lenders, a well-presented application can be the difference between an easy approval and a decline.

Key Takeaways:

• Securing a mortgage as a self-employed first-time buyer is primarily about clearly proving your income; it is not inherently harder than for an employed person – just a different process.
• Most lenders prefer to see two full years of self-employed accounts, but there are options available for those who have only been self-employed for one year.
• Lenders will typically lend around 4.5 to 5.5 times your provable income, which is calculated based on net profit for sole traders or, for limited company directors, sometimes includes retained profits in the business to boost the amount you can borrow.
• The required deposit for a first-time buyer starts realistically at 5%, and self-employed individuals have access to the exact same mortgage products (fixed rates, trackers, repayment mortgages) as employed applicants.
• To improve your chances, gather all necessary documents (tax forms like SA302, up to six months of bank statements, ID), check your credit file for accuracy and avoid new credit agreements before applying.
