Types of buy-to-let mortgages
There are various types of mortgages, such as a fixed-rate or tracker-rate mortgage. You can read below to find out about these. At TSB we offer both fixed rate and tracker rate buy-to-let mortgages.
Fixed-rate mortgage
With the fixed-rate buy-to-let mortgage, your interest rate will remain the same for a set period, such as 5 or 10 years. The benefit of a fixed-rate mortgage is that it helps you to budget more easily, because your interest rate will stay the same for the entire length of the deal. However, if you switch away from the mortgage before the fixed-rate period ends, you can be charged early repayment charges. Initial rates for fixed-rate mortgages also tend to be higher than tracker-rate or variable-rate mortgages. You can find out more about the fixed-rate buy-to-let mortgages we offer below.
Tracker rate mortgage
With a tracker rate mortgage, the lender sets the pricing which will be a margin above Bank of England base rate (BBR) at that time. As the base rate increases or decreases, so does the interest rate on your mortgage. As the interest rates drop, your monthly payments will too. However, if the rates increase, you need to make sure your budget can cover these higher monthly repayments. Early repayment charges will sometimes apply if you switch away from the mortgage before the tracker deal period ends.
