A variable-rate mortgage is a loan where the interest rate of the loan is variable from the start. The value of the variable rate is determined by referencing a benchmark rate. In the UAE, EIBOR is used as a benchmark to determine the variable rate. E.g. Variable rate = 3Month EIBOR rate + 2% mark up. I.e. if the 3Month EIBOR rate is 0.4% then the variable rate will be 2.4%. Usually, the variable rate is determined by referencing the benchmark rate on the day the repayment is calculated.
