The cost of one point is one percent on the loan size and discount points appear on Line 802 of the HUD-1 Settlement Statement.
As a general guideline, each point paid lowers a mortgage lender's offered interest rate by 0.250%.
For example, a $200,000 home loan offered at 6.000% can be had for 5.750% if the borrower agrees to make an up-front payment of one point ($2,000).
In addition to lowering your interest rate, discount points are usually tax-deductible, too. Therefore, be sure to provide any settlement statements from the previous calendar year to your accountant during Tax Season.
Lastly, as an added note: discount points should not be confused with origination points, a one-time charge for the lender's service appearing on Line 801 of the HUD-1 Settlement Statement. Origination points are not tax-deductible.
