I'm open to suggestion regarding strategy and location and willing to put in more work for better returns, but I certainly need to grasp a better understanding of the process to get started across the border. 

My suggestion, buy what you know around you, do add risk by buying OOS when you are in a great location.

A quick internet search suggests that foreign national loans can provide up to 75% LTV.

I suggest consulting with a real estate attorney to ensure proper structuring of the LLC/land trust and review the tax and insurance implications.

Suggesting to them buying their house for a wholesale range offer or lower dependent on the extent of the rehab, then having a contract in place that gives them a percentage of the profit to help get them back on their feet, paying off debts etc.

I would suggest getting Dave Ramsey's book called The Total Money Makeover and read that.

The only other question I would suggest is that you do engage a property management company to review your quad and review your monthly financials.

I’d suggest focusing on securing solid DSCR loans—like those from thelender.com, which lends up to 80% LTV, considers STR income, and operates as a direct lender.

I would suggest partnering with another investor with some deals on their track record and/or some money to contribute to the deal.

Quote from @Jason Hatfield: @Jaycee Greene  they require a non refundable deposit and give 48hrs to see proof of funds I would suggest developing a relationship with an HML/PML that would give you a "guidance line" that would basically be a "pre-approval" for situations like this to present to the buyer/auction company.
