Adjustments in the effective rate of interest shall (1) be made on an annual basis; (2) be limited, with respect to any single interest rate increase, to no more than 1 percent on the outstanding loan balance; and (3) be limited to a maximum increase of 5 percentage points above the initial contract interest rate over the term of the mortgage.
