My experience may be useful only for sf, but I live in the city in a nice (by my definition of nice: 100+ years old, solid wood floors, plaster walls, detailed woodwork, thick aged wooden doors, handmade ironwork) apartment. My landlord would like to sell the place to us, but our rent doesn't even cover the mortgage with a $100K downpayment. By the time you add HOA fees, insurance, taxes, and a 3-5% of value annual maintenance investment, my landlord pays me some $800-$1000/month to live in his apartment. Which is fine by me.
