I was in the property business a long time ago when I couldn't sell a condo after I had also bought a house... and decided then and there that I wanted to neither be a landlord, not be in the house-flipping business.

My former mother-in-law was a realtor, and she was eternally "resale value, resale value, resale value" and I was "I want to LIVE here for ME, not for someone who buys this place 10 years from now." To her, it was almost unthinkable that someone would stay in the same place more than 3-4 years...
