It’s a pattern that’s been repeated for a long time. Move into a city when young and move out when it’s time to have a family.
I was glad I had the chance to live relatively cheaply with an apartment and roommates and save 50% of my post tax income in a large expensive city and then move out to a cheaper smaller city when I got married, bought a house, and had children.
Are you the guy in the “I’ll never get married” commercial ? ;-)
