Seeking seasoned advise. I am in my mid 30s, single no children; carrying a 68k mortgage on a 130k condo since 6 month ago, at interest rate of 3.125%. My officemate, self proclaimed "financial guru" explained to me today that her understanding is that one should carry the longest possible mortgage, so one can put all the extra savings into the (stock) market for the longest, strongest return. many stories (including MMM's own) seem to point that folks want to pay back the mortgage as soon as possible. I am a bit confused, what is the right thing to do? I'm currently more than half way saved to my personal goal of FI at the rate of (saving) 65% gross income per month.
Thanks in advance!
