Self-Employed Net Profit Mortgage

How does my net profit affect the maximum mortgage I can get?

This is a really interesting point. The figure we use for your income might not actually be your income. We just touched on it – where there can be an average or a lower figure.

But once we get to the absolute figure we’ll use, that’s a big driver on how much you can borrow. If a bank is going to give you five times your income, obviously that figure will be more if your income is higher.

Some banks are more cautious and may offer 4.5 times your income. But one lender today, as we talk in October 2025, is going as high as 6.5 times income. There’s a massive range.

If your income is £75,000 or above, you can get into those higher multiples. The reason is that bread and milk cost the same for everyone, so once your income reaches a certain level, you have more disposable income in percentage terms.

There’s also the high net worth exemption, where none of the rules I just explained apply. The FCA says that if your income is £300,000 – so in this case, your net profit is £300,000 or more – or you have £3 million worth of net assets, you’re seen as high net worth.

Banks can be a lot more flexible in this space, and we do find disproportionate numbers of limited company directors here.

One other area that we cover on the website is retained profit, which I won’t talk about now.
Essentially, higher earners might not want to draw all the profit – and if that applies, take a look at the retained profit section.

Can I get different income multipliers based on net profits when applying for a mortgage? Do lenders apply a lower income multiple for self-employed applicants?

Quite a few of the main high street banks do arbitrarily cap how much they’ll lend you at 4.49 times your income.

It’s 4.49 for some banks, whereas others will give you 5.5 as standard. Some lenders will deem self-employed people more risky, but not all banks do.

Your absolute income is a big driver as well – and a higher earner can certainly go further. Let’s just say you do your day-to-day banking with Lender A. If they’re one of the banks that cap your income, if you had £100,000 income, they’d only offer you a loan of £449,000.

But Lender B – maybe even the bank next door – will lend you £550,000. It just brings to life that there’s a huge variance. The beauty of being a broker is that we’re not tied to any particular lender. We’ll go to the one that’s most applicable for you.

Can you use projected income to get a mortgage?

You can, but not as often as you used to. Things were very different before 2008 – basically, if you got a note from your mum you could get a mortgage then.

Today, you can use a projection, but typically there’s a reason. As a very specific example, we had a client who owns a warehousing business, and he had to buy lots of infrastructure for that. He had a huge capital outlay to get new robotic infrastructure in place.

It hugely dipped his profit – but we got a projection from his accountant to explain it was a one-off event, and where the business will be next year and thereafter.

I’ve had another one recently where a company bought another business – again, with a huge dip in profit. That’s where predictions are really useful. We just explained why this other company was bought and how that will improve profits next year.

It can also be that you’ve not been trading long. There just needs to be a reason. It’s a bit more niche, but one or two of the high street banks allow it. Some smaller building societies are brilliant at this because they’ve got the capacity to underwrite manually. So, if we can’t go through the standard assessment, that’s an option we can explore.

Is there a maximum loan to income ratio when using net profit?

Yes – and we touched on this with the affordability multiples. It is also often linked to Loan to Value (LTV), as well, which is the percentage you’re borrowing against the property value.

It’s almost like a matrix, in that some banks will lend you 5.5 times your income up to 75% of the property value, but then 4.49% after. Other banks don’t have that restriction. So the affordability multiples are one thing, but it’s also linked to the equity in the property or the deposit you’re putting down.

Are there any minimum income thresholds for self-employed applicants?

Not really. But the higher the income, the more you can borrow. It’s LTV-restricted, but there’s no minimum. If you have a very low income but you don’t need to borrow much, great.

These things are relative and most people are quite sensible. Very rarely do I speak to someone whose income is £10,000 and they want to borrow £1 million. People tend to put themselves in the right bracket, give or take.

Are there different requirements for sole traders versus limited company directors?

For sole traders it’s actually a bit simpler – you’ve got your profit and loss and you just prepare your tax returns.

For limited companies we can also look at the accounts. Are you retaining profits? Are you drawing more out in salary and dividends? Again, there is a specific podcast on limited company directors to explore.

For a limited company, there are other ways of doing things. But the requirements are broadly the same. For a limited company director we can look at the accounts, which sometimes is beneficial, but banks will always accept your tax returns. It always goes back to the most favourable assessment – and that’s the path we’ll go down.

If I operate under multiple businesses, how do you assess total income?

It’s all added together. I mentioned the tax return in the last question, and a specific document called your SA302. SA stands for self-assessment and the 302 is the response to the SA100 that you submit. Anyone who’s self-employed knows these terms.

A lot of people have their SA100, but that’s just a submission. It doesn’t mean HMRC have agreed with it, and so the SA302 is the best document. These used to be issued to everyone, but now they can be requested – you get it in 48 hours or so.

If you have multiple businesses, that’s a simple document with all of your income in one place. It’s all broken down and straightforward. If we can’t get that, we’d go for an accountant’s reference. We can also get the accounts for the various businesses, as well. We just simply add it all together.

How can a mortgage broker help here? Have you got anything else to add?

Funnily enough, most of these questions show why brokers are so important. You’re my client and I work for you. The best thing to do is sit down and explain what you want to achieve, and then let me worry about how we get there – because that’s literally what I get paid to do. On top of that, we get exclusive rates and preferential treatment from lenders.

When you’re self-employed, it is more complex. With the greatest of respect, if you walk into an average bank branch, they might not know all these terms.

You’re busy running your business. You’ve got better things to do with your time than dealing with all this, so let us do the donkey work. We’ve got direct access to underwriters which always helps where things don’t fit in a system.

Ironically, even this morning, I’ve been dealing with a self-employed client who just doesn’t fit the norm. She was never going to tick all the boxes in our fact-find, but that’s no problem. We’ll deal with that and make her life easy – we make the whole process work.

Key Takeaways:

• Lenders primarily calculate mortgage affordability for self-employed applicants based on the net profit of the business, often requiring tax documents, accounts, or an accountant’s certificate.
• The minimum requirement is one year of trading and accounts. Having two or more years opens up the entire market.
• Lenders use different methods to assess your net profit. Some use only the most recent year’s figure, while others may take the lowest figure or an average, especially if profits have dropped or risen.
• The maximum mortgage amount is a multiple of your assessed income, which can range significantly between lenders (from 4.49 times to 6.5 times income). Higher incomes (typically £75,000 and above) may qualify for higher multiples.
• A mortgage broker can help self-employed applicants find the most suitable lender among the varying criteria and directly engage with underwriters for non-standard or complex income situations.
