The returns don’t seem substantially better than an index fund, it’s a headache to deal with, and if housing actually becomes affordable then you’re upside down (and the govt might air drop cash on upside down mortgages, probably not if you’re already paid off).
Not my forte though and I hand-waved the hell out of that math, maybe I’m way off. Just feels like a ton of capital to tie up for mediocre returns.
A beach house makes some more sense because you get the utility of being able to use it, which is worth something if you like to vacation to the same place.
