From the Bay Area, $1.5M will get you a two bed one bath or three bed 1.5 bath home built in 1925 or so. You can buy in a lower end neighborhood for a little less or a higher end one for a bit more, but the standard is going to be a craftsman home from 1906 with a driveway if you’re lucky.
I think the graphic also used a 20% down payment and a slightly over 6% mortgage in the calculation.
I just want to retire and move someplace cheap, like NYC or London.
