Mortgage points mean a certain percentage towards a current loan. Since you were required to pay an additional 2.5 points, that would mean paying an extra 2.5% of the current load. To show this:

175210 * 2.5% = 4380.25
175210 + 4380.25 = 179590.25

Therefore, the new cost of the home would be $179,590.25
