Quick answer: Yes, self-employed people can get a buy to let mortgage. Lenders mainly assess the expected rent rather than your personal income, though most still check your earnings, credit history and accounts. Many lenders ask for at least a 25% deposit, and some consider 20%.

Buy to let lending works differently from a residential mortgage. Instead of focusing on how much you earn, the lender’s main question is whether the rent will cover the mortgage. That makes buy to let more accessible for self-employed landlords than many expect, as long as the paperwork is in order.
How Lenders Assess the Rent
Most lenders use a rental cover test, also called an interest cover ratio. The expected monthly rent must cover the monthly mortgage interest by a set margin, commonly 125% or 145%, calculated at a notional stress rate set by the lender rather than the rate you will actually pay. Higher-rate taxpayers buying in their own name are often tested at the higher margin, while limited company purchases are often tested at 125%.
How Lenders Look at Your Personal Income
- Minimum income: some lenders set a minimum personal income, while others have none.
- Evidence: SA302s and tax year overviews, or company accounts if you are a limited company director.
- Top-slicing: if the rent falls a little short of the cover test, some lenders let surplus personal income make up the gap. Self-employed income needs to be well evidenced for this to work.
Self-Employed Buy to Let at a Glance
| Situation | How lenders typically respond | What helps |
|---|---|---|
| Two or more years of accounts | Widely accepted | Up-to-date SA302s or accounts |
| One year of accounts | A narrower group of lenders | Strong rental cover and deposit |
| First-time landlord | Accepted by many lenders, some restrict it | Owning your own home, clear rental evidence |
| Buying through a limited company | Assessed on the company, directors give personal guarantees | Experienced accountant, clear company structure |
| Four or more mortgaged rental properties | Portfolio landlord assessment of your whole portfolio | Property schedule, business plan, cash flow |
Worked example
Leanne is a self-employed hairdresser buying a flat expected to rent at £1,250 a month. At a 125% rental cover test, the lender needs the rent to cover 125% of the monthly interest at its stress rate. That means the stressed monthly interest can be no more than £1,000 (£1,250 ÷ 1.25). The lender converts that £1,000 into a maximum loan using its own stress rate. If the rent falls short, a lender that allows top-slicing may use Leanne’s surplus personal income to bridge the gap, which is where clear self-employed accounts make a difference.
Portfolio Landlord Rules
If you own four or more mortgaged buy to let properties, lenders treat you as a portfolio landlord and look at the whole portfolio, not just the new purchase. Expect to provide a property schedule, rental income and mortgage details for each property, and sometimes a business plan. Self-employed landlords should keep their own trading income and rental income clearly separated in their records.
Tips for a Stronger Application
- Get a realistic rental estimate from a local letting agent before you apply
- Keep your tax returns filed and your SA302s ready
- Check your credit file for errors before a lender does
- Decide early whether to buy personally or through a limited company, and take tax advice
- Use a broker to match the rental figures and your income to lenders whose criteria fit
Frequently Asked Questions
Can I get a buy to let mortgage if I am self-employed?
Yes. Buy to let lenders mainly assess the expected rent from the property, so self-employed landlords are widely accepted. Lenders still check your personal income, credit history and, in some cases, a minimum income level.
Do I need accounts for a self-employed buy to let mortgage?
Usually, yes. Most lenders ask for SA302s and tax year overviews, or company accounts, to confirm your personal income. Some lenders are more flexible where the rent comfortably covers the mortgage.
How much deposit do I need for a buy to let mortgage?
Many buy to let lenders ask for a deposit of at least 25%, and some will consider 20%. Being self-employed does not usually change the deposit itself, though the rent and your experience as a landlord can.
What is the rental cover test?
Lenders check that the expected rent covers the mortgage interest by a set margin, often 125% or 145%, worked out at a notional stress rate. The margin can depend on your tax band and whether you buy personally or through a limited company.
Can I buy a rental property through my limited company?
Yes. Many landlords buy through a special purpose vehicle limited company. Lenders then assess the company and usually ask the directors for personal guarantees. Tax treatment differs, so take tax advice as well as mortgage advice.
