My parents have recently divorced and I chose to stay with dad. Our family home was quite big, with a yard, patio,… now my dad rents a studio - we have living room, kitchen, bedroom (1 room) + bathroom + balcony. I actually really love it, it’s very cozy, intimate, nicer location, easier to clean, less clutter…
Big houses kinda suck in many ways. Bigger HVAC system to replace. Bigger roof. More flooring. More paint. More cabinets. More plumbing fixtures. Bigger tax bill. Bigger utility bills. All of that means more time and many to maintain or replace.
