Final answer:
After calculating the savings over the 30-year life of the mortgage, purchasing the three discount points would save Shelly $11,040 after accounting for the initial $3,000 cost. Therefore, buying the points seems to be a financially beneficial decision in the long term.
Step-by-step explanation:
To determine if mortgage points are worth it for Shelly, we must calculate the savings over the life of the loan. With an interest rate of 3%, her monthly payment amounts to $421, whereas buying three discount points reduces the rate to 2.75% and her payment to $382 per month. The cost of the points is $3,000.
First, calculate the total payments without points:
- Without points: $421 * 12 months * 30 years = $151,560
Next, calculate the total payments with points:
- With points: $382 * 12 months * 30 years = $137,520
Now, subtract the cost of the points from the savings to see the net benefit:
- Savings with points: $151,560 - $137,520 = $14,040
- Net savings: $14,040 - $3,000 (cost of points) = $11,040
In this case, the points save Shelly $11,040 over the life of the loan. So, buying the discount points would be financially beneficial in the long term.
