Buy-to-Let Mortgages

Buy-to-let mortgages work differently to residential ones. From affordability calculations to ownership structures, we'll make sure you understand your options and find a suitable mortgage based on your circumstances.

The headline figures every buy-to-let investor should know up front:

Around 25% deposit

A 25% deposit is a common starting point for buy-to-let mortgages. Some higher-LTV products may allow a smaller deposit, while other applications may require more.

Typical 125% to 145% rent cover

Lenders commonly want the expected rent to cover around 125% to 145% of a stressed mortgage-interest calculation. The percentage and stress rate vary between lenders, applicants and products.

From high street to specialist BTL lenders — including limited company and HMO products.

How affordability works

Buy-to-let lenders typically assess affordability using the expected rental income and a rental stress test. Some lenders also have minimum personal-income requirements or take your wider income and finances into account.

125–145%

Rental stress test

Expected rent typically needs to cover 125–145% of the mortgage payment at a stressed interest rate.

We'll help you understand what this means in practice and how much you can realistically borrow against a given property.

Limited company vs personal ownership

A rental property can be bought personally or through a limited company, often a special purpose vehicle (SPV). Neither route is automatically better, and the mortgage products, costs and tax treatment can differ. Our guide to limited company buy-to-let mortgages explains how lenders assess the company, property and people behind it.

Personal name

Simpler and cheaper to set up. Mortgage interest relief is restricted, so higher-rate taxpayers often pay more tax on rental profits.

Limited company (SPV)

  • Mortgage interest fully deductible against profit
  • Profits taxed at corporation tax rates
  • Easier to build a portfolio over time
  • Higher setup, accounting and mortgage costs

First-time landlord guide

If you’re buying your first rental property, we’ll help you understand the deposit, rental-affordability and lender requirements that may apply. Criteria for first-time landlords vary, particularly if you do not already own your home.

Tax considerations

Tax treatment can differ depending on whether the property is owned personally or through a company. It can also affect how mortgage interest, rental profits and a future sale are treated.

We don't provide tax advice. We'll explain the broad implications and recommend you speak to a qualified tax adviser about your specific situation.
