15 Yr vs 30 YR Mortgage

[Craig J.]

I am getting into real estate a little late in life, as I am now 57 YO. I am looking at investing into multi-family homes. If I get these soon and mortgage to allow renters to defray mortgage and use 30 Yr mortgage, I would be 87 before they are paid off. Why would not I want to pay these off early and enjoy the increase in pay in my later years? Mortgage rates are low and both should be affordable.
