I have extended family in MN, which is a plus and something I’m factoring in as well.I’ve heard from friends in Iowa that MN winters are on another level, which will definitely take some getting used to. 

Are you looking to live in one unit and rent the others? 

Also a mortgage lender with United Mortgage Corp.

Where do you live, and where are your units? 

. - Put downward pressure on demand: I personally believe it is unlikely that Trump actually deports millions of illegal immigrants who have settled in the United States.

I'm going to reiterate what's already been mentioned above, but I'm going to actually give you examples of why it's relevant to you to find a U.S. tax professional.1 - You're going to need to file U.S. taxes once you have property down here, there's federal filings, state filings, and sometimes local filings too2 - Tons of tax treaties between the U.S. and Canada that are easy to miss and can cost you a lot of money (important one with rentals - effectively connected income - if the professional you talk to doesn't know what this is, run away)3 - The amount of days you spend in the U.S. needs to be tracked and if you go over a threshold, all of your worldwide income could be taxable by the U.S.4 - Selling real property means up to 15% of your sales proceeds might not be available to you for years (FIRPTA)5 - Lots of nuance at the state and local levels, which both want to take as much money from you as possibleMain takeaway here is that you should find a U.S. based tax person.

Multi family can range from about $60k-$125k/unit.

I have two duplex units and am subdividing into townhomes for higher market value.

- Given your experience level, without an inspection, I'd turn around and walk away.

That just adds a level of complexity to everything.I think there is so much opportunity in the US, that why would you try to complicate everything x10, but investing in someplace like Spain.
