Buy to Let Mortgages: Frequently Asked Questions

What is a buy to let mortgage?

A buy to let mortgage is designed for people who want to buy a property with the intention of renting it out to tenants. Unlike residential mortgages, lenders assess buy to let applications primarily on the property’s rental income rather than just the borrower’s salary.


How much deposit do I need for a buy to let mortgage?

Most buy to let lenders require a minimum deposit of 25% of the property’s value, although some may ask for more depending on the property type, your experience as a landlord and the lender’s criteria. A larger deposit can often lead to more competitive interest rates.


How is buy to let affordability calculated?

Buy to let affordability is usually based on rental stress testing. Lenders typically require the expected rental income to cover between 125% and 145% of the mortgage payment, calculated using a higher stress interest rate. Your personal income and outgoings may also be taken into account.


Can first time buyers get a buy to let mortgage?

Some lenders allow first time buyers to apply for buy to let mortgages, but options can be more limited. Lenders may apply stricter criteria, and in some cases you may need to already own your own home. A mortgage broker can help identify suitable lenders for first time landlords.


Can I live in a buy to let property?

No. Buy to let mortgages are specifically for rental properties. If you intend to live in the property yourself, you will usually need a residential mortgage. Living in a buy to let property without lender consent can breach mortgage terms.


Are buy to let mortgages interest-only?

Many buy to let mortgages are interest-only, which helps keep monthly payments lower. However, this means the original loan amount must be repaid at the end of the term, usually through property sale or other investments. Repayment options are also available.


What interest rates apply to buy to let mortgages?

Buy to let mortgage rates are generally higher than residential mortgage rates. Rates vary depending on your deposit size, property type, experience as a landlord and whether the property is owned personally or through a limited company.


Can I get a buy to let mortgage through a limited company?

Yes. Many landlords choose to purchase buy to let properties through a limited company. Limited company buy to let mortgages work differently, often involve personal guarantees from directors and may have higher rates or fees. Specialist advice is recommended.


What fees are involved with buy to let mortgages?

Common buy to let mortgage fees include:

  • Arrangement or product fees

How many buy to let properties can I own?

Do I need landlord insurance?

Yes. Standard home insurance is not suitable for rental properties. Landlord insurance typically covers buildings, liability and loss of rent. Some lenders require proof of appropriate insurance before completion.


Can I remortgage a buy to let property?

Yes. Many landlords remortgage buy to let properties to secure better rates, release equity or restructure their portfolio. The process is similar to residential remortgaging but focuses on rental income and lender criteria.


Is buy to let a good investment?
