Really, rental is the only issue, and with almost $200k in the bank, finding something in the school district shouldn’t be impossible.
Regarding moving, Americans are way too attached to their “stuff”. There’s so much unwanted junk floating around out there that one can easily buy new furniture off Craigslist or from a thrift store.
Apart from books, one old writing desk, everything else that I’m attached to could fit in a few milk crates. If kids are trained not to get too attached to material stuff at an early age, it will be easier for them down the line.
