Reading Abundance & they actually have a nice little section on the 30-year mortgage:
The 30-year mortgage was possible only because the federal government guaranteed it. They claim that 30-year mortgage (which truly is kind of a crazy thing when you think about it) would never have stood up in a free market w/o gov't support.
They also point to Japan (Tokyo in particular) trying 50 – 100 year mortgages to make housing more “affordable”, which led to a crazy spike in property values, then a big time collapse in values that haven't recovered three decades later.
Agree w/ @brandondonnelly.eth that longer mortgages will likely lead to higher property values & more risk in the housing market.
