That tipping point came last year for me and I moved to suburbia for exactly the reasons above. Zero regrets and I get to have space to have a real garden and fruit trees on my property. Couldn't ever get that in high-density housing environment.
+1 and i still live in a condo complex. But my rent is only 66% what it was, my place is 10% larger, yes I spend a tiny bit more on car costs. But frankly I am happier here than I was living downtown San Francisco.
