Types of buy-to-let mortgages explained
It is possible to get a repayment buy-to-let mortgage but most mortgages for buy-to-let properties tend to be interest-only.
With an interest-only mortgage, you only make monthly interest payments. You pay off the mortgage balance (the amount you borrowed for the property) at the end of the mortgage term via a repayment vehicle or when you remortgage.
You can also own a rental property in your personal name or through a buy-to-let limited company.
