paying off low interest mortgage early
paying off low interest mortgage early Could someone please help me with my math. I am lucky to have a sub 3 rate on a 30 year. I've been adding extra each month in order to reduce principal. Everyone says I am crazy since I am only "earning ~3%" on that extra payment when I can get a Treasury or something else for 5%+. But isn't the fact that those extra payments go toward principal...
