Final answer:
To cover the closing costs, it would take approximately 18 months.
Step-by-step explanation:
To calculate the approximate number of months it would take to cover the closing costs, we need to calculate the monthly savings from the reduced payment:
Monthly savings = $890 - $780 = $110
Next, we divide the closing costs by the monthly savings:
Approximate months to cover costs = $1,950 / $110 = 17.727
Rounding up to the nearest whole number gives us approximately 18 months to cover the closing costs.
