The points are better explained with an example so we are going to use one to understand when does it make sense to buy a point.
Let us take an example of a three hundred thousand dollar loan. One point is one percent of the loan amount which is three thousand dollars.
If the loan estimate provided by your loan officer says that there is half a point to get a 2.625% on a thirty-year mortgage, that means you have to pay $1,500 to the lender just to get 2.625%.
The monthly payments including principal and interest on 2.625% for 30 years are $602.48.
What you need to understand is when you pay that half a percent of the loan amount, how low of the rate are you getting.
If your lender is offering a rate with a buy-down point you also want to ask the lender what rate you can get without any mortgage points.
In this example we will take the interest rate that the lender can offer without points is 2.99%.
Once you have that you want to see how much is the difference in the monthly payments between both the rates.
The monthly payments including principal and interest on 2.99% for 30 years are $631.60.
If you are paying one point to lower your rate on an average you will get a quarter of a percent reduction on your rate and will have a difference of approximately twenty-nine dollars per month.
What you need to do is calculate how much time is it going to take to recoup the point charged and analyze if you are planning to stay in the house for that long.
In our example, it would take approximately 52 months, which is about four and a half years to recoup the points charged.
So it would make sense to buy down the mortgage points in this example only if you are planning to stay in this house for four years and three months or more.
If you are not planning to stay in the house for the time it takes to recoup the loan points charged, you might as well get a rate without any mortgage points.
The math to calculate if it makes sense to buy a mortgage point is given below.
