What is a Buy to Let Mortgage?

A Buy-To-Let Mortgage is a loan designed for purchasing residential properties that you plan to rent out to tenants. Unlike standard home loans, lenders focus mainly on the property's potential rental income rather than your personal salary. This makes mortgages specifically suited for property investment. Understanding this helps you plan your finances and choose the right property.

Most mortgages operate on an interest-only basis, meaning monthly payments cover only the interest. The loan principal is not repaid during the term. At the end of the mortgage, you need a clear repayment strategy, such as selling the property, remortgaging, or using personal savings. If you plan to rent, offering it through corporate accommodation services can help maintain rental income and reduce void periods.

How Does a Buy-to-Let Mortgage Work?

Buy-to-let mortgages operate differently from standard residential mortgages. Lenders determine how much you can borrow based on the property's expected rental income. Typically, rental income must cover 125 to 145% of monthly mortgage payments, ensuring a buffer for void periods and unexpected costs. Working with professional London property management can help you maximize rental income and efficiently manage your investment property.

Interest rates on mortgages can be fixed or variable. Fixed rates provide stability, while variable rates may change with market conditions. At the end of the mortgage term, you'll need to repay the loan. Common repayment options include selling the property, remortgaging, or using personal savings.
