No, I definitely wouldn't argue that "need" is the right word. We did need to see that to know we don't want it though, so it was an important step in the process. We have (will have in Oct) three boys and we're both full time WFH so we're falling into the trap of wanting 3 rooms for the kids, a master bedroom, and 2 office spaces for us, and that drives the space need a little unreasonably high. Our current house is like 2,800 listed sq ft but more realistically 3,300 with the bonus areas.
We need to find our sweet spot. The two young boys can share a room just like I did with my brother growing up. I could downsize my office into the old nursery, turn this above garage space into bedroom for two of the boys since they're 2 years apart. Upgrade our Master Bath and Kitchen. We'd survive for 10 more years her. And just because we could afford it doesn't mean we should. I'd much rather continue juicing our Roths, SEPs, HSA, kids accounts, and spending frivolously on guns.
