Canadians owning homes in the US pay "double" the property taxes, no other issues other than not staying more than
6 months in the US or you can lose your health care (at least in Ontario you do)
I spent some time in Gilbert AZ last winter and am planning to stay for 2-3 months this winter - renting a home (worth 700,000) with pool, lawn and sprinkler servicing, basically maintenance free. very reasonable rent
