I bought my house in 1985 because where I was renting I couldn't have a greenhouse. For the first nine years I lived in the granny unit and rented out the main part of the house so I could afford the mortgage. The first time one friend visited he remarked "I've known people who lived in smaller. They all had bars on the windows." I was a potter at the time and that is a low paying job, even in the arts. It is amazing what you can do if you want it enough.
