A Fixed Rate Loan allows you stability by fixing your home loan repayments at a set amount over a set period of time.
The main benefit of a fixed rate loan is locking in your repayments for a period of five years should interest rates rise sharply as they did during the 1990s reaching 17%. However, locking in your repayments at the peak rate of 17% would cost you money.
Most people choose variable interest rate home loans knowing that over a period of time they will always be significantly cheaper.
