I will acknowledge that owning a house is sometimes like having an extra part time job. I'm forever fixing little things or gardening or changing things about the house. I consider this to be a new hobby, but if you consider it work then that's something else to consider.
edit: I put our loan details into the NYT calculator and it said "If you can rent a similar home for less than... $1,618 PER MONTH... then renting is better." That might get you a 1 bedroom condo around here, instead of a 4 bedroom house with a yard like we got.
