My iniital thoughts are that they're on track (a bit ahead, actually) for retirement but don't have any dedicated college savings. I know some private school parents just think they'll transfer those payments directly to college but I don't think that logic holds if you're only paying $17k/year. I can see the appeal of a condo that includes everything including utilities/laundry/gym, but they still may regret the decision when it comes time to sell.
Honestly between being overwhelmed by taking care of a house to having her parents give them lump sums for
multiple down payments to her parents giving them $10k toward a car purchase when she was 34 (!!), the whole thing reads like cosplaying as grownups while waiting for her parents to die so they can be rich. I have a hard time believing they'll be able to support their son the way her parents are supporting them.
But good for them in being able to have a very low stress life in a HCOL area.
