But presumably you live in that apartment because you needed to be within commuting distance of the Manhattan office? If you don't need to be so close to Manhattan I would guess (not really knowing anything about your situation) that you could afford a mansion in a town or village instead.
Some people like living in big cities, and are ok trading off a bigger living space to make that happen. I love being able to walk out to a bunch of different restaurants, having easy access to entertainment venues, etc. The idea of having a giant house in the middle of nowhere has very little appeal to me. This is especially common for younger people and those with no kids.
There's a whole world between big city and the middle of nowhere. You can live in a small town with restaurants, culture, coffee-shops, a theatre, social life.
I suspect if WFH becomes the norm, then people will flock to big cities even more, because suddenly you live in a massive suburban house but can go days without ever seeing a new face.
At least when you had a central office there was a place where you would meet some people and be in the middle of some sort of hustle and bustle.
Big cities might become even more attractive in a WFH future .
Don't you have towns and villages? Like a sub-urban area but only a few miles across and then you have shops and community in the middle within a walkable distance? I live in a town and I work from home but there's a coffee shop, a sandwich bar, a pub, a little club, a theatre, a gym, and I meet people from the community here. I'm married but I'm sure people date here as well. I thought 'small town America' was a big part of the culture?
