Are there various strategies/corporate structures that can be employed to minimize the tax obligation to Canada when investing in the states?

I work in IT but have found the corporate world doesn't fit my independent spirit.

Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

It doesn't stand alone like a corp or LLC with a corp election.

Traveling nurses and other professionals search this area often with the considerable amount of hospitals, medical facilities and corporations in the surrounding cities. 

I'm hoping to leave the corporate world as soon as possible to pursue building my dream. 

It's great that you have residency in Mexico and that you have a Mexican corporation.

I saw your corporate announcement.

As you write checks and make deposits your income tax return is preparing itself.At the end of the tax year print a simple Profit and Loss report for the time period and hand it to your bookkeeper or CPAYou still need to keep receipts for seven years or so but the works does itself as you write and code each check.Even if you file as an LLC, Partnership or corporation your CPA will thank you.

In my opinion, I would not take the advice you received regarding using OPM is you have no experience in investing in real estate.I would also not look to be a private lender for several reasons1) You are better off putting your money with a corporate bond / CD and get 5-6% with little risk compared to 10% to 12% with much more risk given today's market conditions2) You won't be able to retire getting interest income, which you said is your goal.
