"You borrow money at today's dollars and pay it off with tomorrow's dollars"
That is outright garbage, Home loans never fall below inflation. If inflation goes up, then your home loan goes up, banks are not going to let you inflate your debts away. Thats why home loans went up to 17.5% a few decades ago because you pay out any added inflation on the loan while owning it.
Housing is just a savings plan, unless you bought and held through a bubble on the up side, thats the only way to get rich.. but you really want to be smart enough to realise that so you dont hold through a bubble on the down side as well.
