Choate definitely expected ALL future cash flow going to ANY type of savings/investment accounts to be available for BS. I remember posting four years ago how this would put a four-year hole in our retirement funds and @neatoburrito quickly pointed out that many would be happy to trade that hole for having any retirement savings at all, and I haven’t complained since. I needed that slap, neato.
I’m still astounded, though, by @WinchesterMom’s announcement that Mercersburg expects 529 funds to be drained for BS when they are ineligible for secondary education and will incur a penalty on top of the misuse. If anyone else’s school does this, please post so future applicants can seriously consider whether this is a viable choice for their family. It certainly wouldn’t be for ours.
