Buy To Let Mortgages

With over 40 years’ experience, Ward Goodman provides clear, independent guidance as a trusted buy to let mortgage adviser, helping landlords compare options, understand lender criteria, and make confident long-term decisions.

What Is A Buy To Let Mortgage?

A buy to let mortgage is a specialist loan used to buy a property you plan to rent out, rather than live in yourself. It works like a normal mortgage, but lenders assess your application based on the expected rental income as well as your financial situation.

Because the lender is taking extra risk, these mortgages often require a larger deposit and may have higher interest rates than standard residential mortgages.

How Do Buy To Let Mortgages Work?

Buy to let mortgages are usually structured so that your rental income covers the monthly mortgage costs – most lenders expect the rent to be at least around 125% of your mortgage payments to account for costs and void periods.

There are two main repayment options:

  • Interest-only – you pay only the interest each month, keeping monthly costs lower, and repay the loan amount at the end of the term.
  • Repayment – you pay interest and some of the capital each month so the loan is cleared by the end of the term.

Your lender will also consider things like your credit history, deposit size, and how much rent the property is expected to generate.

What You Need To Apply

To start a buy-to-let mortgage application, lenders will typically ask for a set of financial and personal documents so they can assess your suitability and affordability:

  • Proof of Identity Proof of identity and address (e.g., passport, driver’s licence, recent utility bill)
  • Deposit Details Details of your deposit and where it’s coming from (savings, sale proceeds, etc.)
  • Evidence of Income Recent payslips if employed, or tax returns/SA302s if self-employed
  • Bank Statements Latest bank statements to show income and outgoings.
  • Existing Properties Information on any existing properties you own and any rental agreements.
  • Minimum Deposit A minimum deposit, often around 25% of the property value, though some lenders may accept 20% or more depending on circumstances

How To Apply

To apply for a buy-to-let mortgage you’ll typically:

  • Check Your Eligibility Lenders usually require you to be a UK resident aged 18 or over with a good credit history and a sufficient deposit.
  • Book An Appointment With An Advisor This will help identify suitable lenders and products tailored to your situation.
  • Gather Documentation Submit the documents listed above to support your application.
  • Submit Application This may be completed with support from a mortgage adviser or broker.

How Much Could You Borrow?

The amount you may be able to borrow for a buy to let mortgage depends on your personal finances and the rent you expect to receive from the property. Lenders generally use the projected rental income, along with your deposit and credit profile, to assess how much they’re willing to lend.

They typically look for the anticipated rent to exceed the mortgage payments by a buffer to allow for void periods and other costs.

For example:

Annual rental income = £950 per month × 12 = £11,400
Property value = £180,000
Rental yield = £11,400 ÷ £180,000 × 100 = 6.3%

In this example, the rental yield works out at 6.3%, which suggests a healthy income stream relative to the property price. A stronger rental yield can support a higher borrowing amount because the expected rent is more likely to cover the lender’s income coverage tests.

This is just an illustration – one of our advisers can give you a realistic borrowing estimate based on your exact plans and financial circumstances.

Frequently Asked Questions

Below you will find the most common questions we are asked about Buy To Let mortgages.

A buy-to-let mortgage is a specialist mortgage for purchasing a property that you intend to rent out rather than live in yourself. Lenders calculate how much you can borrow based mainly on the expected rental income, which typically needs to cover a percentage above the mortgage cost to allow for voids and expenses. These mortgages are often offered on interest-only terms, meaning you pay interest monthly and repay the capital later.
Most lenders expect you to be a UK resident, often with a minimum income (e.g., from employment) as well as the projected rental income. You may also need a reasonable credit history, and lenders usually limit the number of properties you already own with mortgages.

Buy-to-let mortgages usually require a larger deposit than residential mortgages.

  • The standard deposit is around 25% of the property price.

  • Some lenders may consider 20% or even 15%, but these deals are less common and often come with higher interest or stricter criteria.

Interest rates on buy-to-let mortgages tend to be higher than standard residential rates due to the perceived higher risk of letting property. Rates vary by lender and term, and can include fixed, variable, or tracker products, with current examples showing a range across different fixed-rate products.
Yes – first-time landlords can apply for a buy-to-let mortgage. However, you still need to meet eligibility criteria for deposit, rental income cover, and overall affordability, just like any other applicant. Speak to a specialist adviser to see which lenders will consider first-time landlords.
Lenders normally require that the expected rental income covers at least around 125% of the mortgage payments calculated at a stress rate, ensuring there’s a buffer if rental income dips or interest rates rise.
Yes – many lenders offer limited company buy-to-let mortgages, which allow a special purpose vehicle (SPV) or limited company to borrow. These mortgages typically have similar rental cover tests and deposit requirements, and may involve additional considerations such as accountancy and incorporation costs.

Costs can include:

  • Arrangement or product fees charged by the lender

  • Valuation and legal fees on the property

  • Broker/adviser fees (if using an intermediary)

  • Early repayment charges if you exit a product early
    Plus ongoing costs like insurance, maintenance, letting agent fees, and tax implications.

Yes – you can remortgage an existing buy-to-let property to secure a better rate, release equity (subject to lender approval), or switch to a product that better suits your plans. Remortgaging involves similar criteria to a purchase mortgage, including deposit equity and rental income checks.
Using a specialist adviser can be very helpful because buy-to-let mortgages have specific criteria and product variations that differ significantly from residential mortgages. Advisers can help match you with lenders who are more likely to accept your profile, potentially saving time and improving your borrowing options.
