A commercial mortgage is a loan taken out to finance ownership of any property you do not live in, meaning buy-to-let mortgages fall into this category alongside mortgages for office buildings or warehouses.
You’ll usually need to provide a deposit of at least 20% to qualify and agree to repay the loan in anything from three to 25 years.
The interest is tax deductible and is generally charged at a higher rate than on a standard mortgage, but at a lower rate than on a business loan.
