Introductory rate loans give you a honeymoon interest rate, usually for the first 12 months of the loan term. Some lenders offer less time and others offer longer. The interest rate reverts to a standard variable rate unless you renegotiate your loan when the introductory period ends.
The discounted interest rate can be either a fixed discount or a discounted fixed rate. The fixed discount is a rate that will be variable but fixed at a certain level or margin below the standard variable rate. This means that for the introductory period, the discounted rate will move with the market. On the other hand, the discounted fixed rate is a rate fixed for the introductory period of the loan term, and won’t move with the market.
