I would argue living below your means is always better. Getting a cheap mortgage you can add an extra $100 or $200 a month to for the first five years makes a TREMENDOUS difference in how much interest you pay over the life of the mortgage and how soon you own it. The first five years of a mortgage are so important, all your payments go to interest. I’ve turned all my 30 mortgages into 15-20 year mortgages by over payments and it’s served me extremely well.
