With a fixed rate mortgage, your interest rate and monthly repayments are fixed for a set time as agreed between you and the lender. You can choose the best time frame for you.
Although a fixed rate means your repayments cannot increase for a set period of time, your repayments will not fall during the fixed rate period. As a result, you could miss out on lower interest rates and lower repayments. Fixed rates may cost more over the long run, but they offer peace of mind as you know your repayments will not rise during the fixed rate period.
We would recommend speaking with a mortgage broker though, you can discuss all rate options and they will help you decided whether a variable rate fixed rate is right for you. They will also be able to do market research for you on the best rates available for you.
