A good time to review your payment amount and consider moving to another lender is upon expiration of your initial fixed rate. A standard occurrence when your initial rate matures is your monthly cost goes up due to the product converting to the bank’s ‘follow on rate’. Your follow on rate will be based on a bank margin plus an EIBOR rate (Emirates Inter Bank Offered Rate), your rate from the point of maturity may vary either monthly, quarterly, half yearly or annually.
