Issa recently found out that he can reduce his mortgage interest rate from 12 percent to 8 percent. The value of homes in their neighborhood has been increasing at the rate of 7.5 percent annually. If Issa was to refinance their house with OMR 2,000 in closing costs in addition to the mortgage balance of OMR 120,056 over a period of time to coincide with his chosen retirement age in 22 years, what would the monthly payment be for principal and interest (hint: closing costs are going to be added to the mortgage)?
