From a certain point in life living at your own place (no matter if rented or not) with no room-mates is non-negotiable, given the financial means to do so. I'd rather live in a studio apartment at the edge of the city (been there, done that) rather than sharing a villa in a beautiful neighborhood with 5 other strangers. If it matters I'm in my mid-30s now, but started feeling that way immediately after I broke up with my wife 5 years ago.
