Buy to Let Mortgages

If you are planning to buy a property, or multiple properties, to rent out, you will need a buy to let mortgage rather than a standard residential mortgage. Buy to let (BTL) mortgages are designed specifically for landlords who want to purchase investment properties to rent to tenants.

How does a buy to let mortgage work?

A buy to let mortgage works much like a regular mortgage in that you borrow money from a lender to buy a property and repay it monthly with interest. However, there are some key differences:

  • The required deposit is usually higher, often 25% or more of the property’s value.

  • Fees and charges tend to be more expensive.

  • Interest rates are typically higher than those for residential mortgages.

These higher costs exist because buy to let mortgages are considered higher risk. Repayments depend on tenants paying rent, and there is always a possibility of rent arrears or periods when the property is empty.

Interest-only mortgages

Most buy to let mortgages are interest-only. This means you pay only the interest each month and repay the full loan amount at the end of the term. Many landlords set aside rental income to help clear the balance when the mortgage ends. Others choose to sell the property at a later date, using the profit from its increased value to repay the mortgage in full.

Who can get a buy to let mortgage?

Lenders will have specific criteria you must meet before being approved for a buy to let mortgage. You should consider the following:

  • Affordability: Deposits for buy to let mortgages are higher than standard ones, so you may need to save in advance. You should also be able to cover the mortgage if a tenant stops paying rent or if the property is vacant.

  • Credit history: Lenders will review your credit record to assess reliability. A poor credit history can make approval more difficult.

  • Income: Most lenders require a minimum annual income of around £25,000 to ensure you can meet repayments if rent does not fully cover the mortgage.

  • Rental yield: Lenders usually expect the property’s rental income to be between 125% and 145% of the monthly mortgage payments.

Other buy to let considerations

Owning a rental property comes with additional costs beyond the mortgage itself. These may include maintenance and repairs, letting agent fees for managing the property, and tax obligations such as capital gains tax if your profits exceed the annual allowance or if you sell the property for more than you paid.

Interest rates and arrangement fees for buy to let mortgages are usually higher than for standard residential mortgages because lenders see them as higher-risk investments.

Yes. You must declare rental income on your Self Assessment tax return. You can usually deduct allowable expenses such as maintenance costs, agent fees, and mortgage interest.

What happens if my tenant stops paying rent?

Can I switch my residential mortgage to a buy to let mortgage?
