The maximal use case! That’s a good way of thinking about it!
I’m struggling with my SO to buy a reasonable house in a high cost of living area. They want a massive 2000 Sq ft monstrosity because we plan to have a kid soon, and I’m thinking 1500 is more than enough. They’re reasoning it’s we need space for each other and entertaining. My reasoning is I want to eat out at the nearby fantastic restaurants nearby more often and buy cheese and wine and stuff.
