Repayment mortgage. With repayment mortgages you pay the interest and part of the capital off every month. At the end of the term, typically 25 years, you should manage to have paid it all off and own your home.
The faster you pay off your principal, the less will go to interest every month. Making biweekly payments will pay more money to your mortgage and reduce your principal and interest faster than a monthly payment. This will result in paying down your mortgage faster.
