You’re currently getting a 10% return PLUS appreciation.  

So, when Trump changes to no tax on tips I feel inclined to change my rental income structure.50% reduction in rent.Previous 50% made up from a mandatory nontaxable tip. 

The GSEs, Fannie Mae and Freddie Mac, both allow the use of foreign income under certain circumstances.In the personal tax returns provided by a borrower, you may see an IRS Form 2555, which identifies the foreign earned income.

I have a friend here who has about 140 houses right now, who I was discussing return on equity with.

These are not taxable events.

@Rud Sev Preferred returns for use of capital in a syndication are typically taxed as interest, not as a return of capital.

Leave you with one last question: Does your reports from any software tie in to exactly your tax return? 

Furthermore you can vastly increase your returns through leverage using a non-recourse loan but that will definitely trigger UBIT but again the numbers can still make a lot of sense. 

The "non conforming" lending options are actually called NonQM (non qualified mortgages).

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.
