A wrench in this plan is the Gen Xer’s kids can’t afford it, either.
I’m in this group. My 3 kids are 20-28 yrs old. There’s no way they could buy a house today [I live in LA], let alone one with spare bedrooms.
I’m sure you’ve heard this before, but would you consider moving from LA? Or encourage your kids to move to the more affordable flyover country? It might be time.
