Canadians Investing in US Multi-family and flips

[Henry Der]

I'm a Canadian looking to invest in multi-family properties in the US, and maybe do some rehab and flips of smaller properties.  Seems to be so many more opportunities there than here.  Would appreciate advice or discussions on the best approach for:

1. legal structure for purchasing properties under

2. Tax implications and best approach

3. Getting mortgages with local US banks as a foreign investor

4. What a Canadian is NOT allowed to do (ie. hammering a nail into your own property, collecting rent?)

Thanks in advance!
