Final answer:
Mr. Ferguson's equity at the time of sale can be calculated by subtracting the remaining loan balance from the property value.
Step-by-step explanation:
Mr. Ferguson's equity at the time of sale can be calculated by subtracting the remaining loan balance from the property value. The loan balance can be determined by the equal monthly payments of $1048 over a 30-year period, which includes 11 percent interest.
Principal amount = Property value - Down payment
Down payment = Property value * Down payment percentage
Loan balance = Principal amount - Total payments made over 30 years
Equity at the time of sale = Property value - Loan balance
Equity at the time of sale = $139,750 - Loan balance
