The loan was written for a 5-year term at an interest rate of 13% per annum, compounded semi-annually. Monthly payments of $1,375 were specified, sufficient to amortize the principal over a 20-year period. The term of the loan is up. All payments were made on schedule. Dave may renew the mortgage for another 5-year term at the current rate of 7.5% per annum, compounded semi-annually. After considering his overall financial position, Dave decides he would like to make weekly payments. However, the maximum payment he can afford is $225 per week. The credit union is willing to allow this change as loan as the loan is amortized at the current rate over the remaining 15 years. What immediate balloon payment must Dave make to reduce the outstanding balance to the point where the weekly payments will fully amortize the loan over 15 years?
