This. The amount of gaudy 2 story mansions that's standing vacant while delapitated and for sale. Most of them end up as rentals as they don't sell, and deteriorate even more in value as they're not cared for. Add this to the inevitable fire insurance quotes you'll get for owning in a place that can accommodate such a monstrous build and it all comes out extremely wasteful and risky.

Aren’t reverse-mortgages big with Boomers too? A lot of them want to die penniless and spend everything lavishly on themselves on their way out. “Let the bank deal with the house after I croak!”

I don't doubt for one second that you're right about this being prevalent as well. Tom Selleck sure tries his best to talk more boomers into this line of thinking.

And it's likely that a lot of the value of their savings that can be realized will be hoovered up by medical providers and nursing homes.

I feel like a lot will also evaporate when Boomer retirement accounts get liquidated to pay off Millennial student loans. As a Gen-Xer I 100% believe this will happen a year after I retire.
