That's the thing. Cost of living is soooo much lower where we are looking, we can get a nice 3000 square foot house for less than we are paying for our current 1000 square foot apartment. Taking into account heating, cooling, lighting, etc it would probably end up about the same if maybe a smidge more. And more is fine since this would be a sizeable increase in income for her. I'm just trying to figure out how big would be good without being excessive.
