Isn't that the entire premise of the thread though? Whether I can put a few hundred a month into paying down principal or investing or I have the entire outstanding mortgage amount available, the relationship stays the same.I agree in general that if someone has the means to earn more interest money than they end up paying in interest over the life of the mortgage loan then they should probably go for it.
I don’t think this is realistic for 80+% of American homeowners though. As I tried to mention earlier haha.
