Buy-to-let mortgages are a lot like ordinary mortgages, but with some key differences:
The fees tend to be much higher.
Interest rates on buy-to-let mortgages are usually higher.
The minimum deposit for a buy-to-let mortgage is usually 25% of the property’s value (although it can vary between 20-40%).
Most BTL mortgages are interest-only. This means you don’t pay anything each month, but at the end of the mortgage term, you repay the original loan in full. BTL mortgages are also available on a repayment basis.
Most BTL mortgage lending is not regulated by the Financial Conduct Authority (FCA). There are exceptions, for example, if you wish to let the property to a close family member (e.g. spouse, civil partner, child, grandparent, parent or sibling). These are often referred to as a consumer buy to let mortgages and are assessed according to the same strict affordability rules as a residential mortgage.
