canadian buying in U.S.

hi there, I live in ontario, I am intrested in investing in the US, is there something I would think of or consider before buying any US properties. note I have never bought any US realistate befor so any pointers will help…
thanx…!!! ;D

just start buying!
my only concern is that getting a loan might be tough.
but if you’re paying cash that’ll work!

i own houses 1000-2000miles away so don’t worry about
that part.
