The following topics are covered below...
Work out your maximum borrowing on a self-employed mortgage
Mortgage lenders tend to use an average of your last three years’ self-employed earnings to calculate the maximum amount you can borrow. Once they have this figure, they’ll apply their standard affordability criteria using a multiple of your annual income.
Most lenders use an income multiple of 4-4.5 times your average earnings, but some may go as high as 5 times or even 6 times if you’re a self-employed professional such as a solicitor or a doctor.
So, for example, if your average earnings over the last three years are £40,000, then, based on the typical income multiple of 4.5 times, you could borrow up to a maximum of £180,000 with most mortgage lenders.
If you’re relatively new to self-employment and don’t have a strong trading background, don’t panic!
If you get in touch with us, we can introduce you to mortgage brokers who have experience arranging mortgages for people with just 2 years of trading history or less than one year.

- Your earnings for either the last three, two or one year (whichever is applicable)
