To calculate their home equity, we need to find the current value of their house and subtract the remaining mortgage balance.
The original price of the house was $100,000, and they made a down payment of $20,000. So, the mortgage amount was $100,000 - $20,000 = $80,000.
Now, they owe $63,980 on the mortgage.
Their home equity is the current value of the house minus the remaining mortgage balance. Since the house has maintained its value, the current value is still $100,000.
Home Equity = Current Value of House - Remaining Mortgage Balance
Home Equity = $100,000 - $63,980
Home Equity = $36,020
So, the correct answer is option C: $36,020.
