Real estate search for NZ: http://allrealestate.co.nz (I used to be lead developer on that website, which is basically the same website as http://realestate.com.au/, and I kinda hate it, so, you know, fair warning. But I still do my own fantasy real estate shopping there, so.)

Flint, MI: count me in!

Buying a house in Canada: I once bought half a duplex in Ottawa, and then sold it again straight away when I was laid off, without ever getting to actually set foot in it as owner. It was before the recent housing market wackiness though. The paperwork was... moderate, I guess? Maybe a half inch or so stack to buy, and rather less to sell? Plus a bit more for the mortgage, which in the end I didn't have to take out, but again less than half an inch.

I don't remember there being anything about farms in it.
