If you buy the right property in Mexico, you can get a higher return by paying cash than if you buy a property with a mortgage in the US, especially right now and you don't have any debt.

Verify the purchase price, potential rental income, and operating costs to determine whether it’s truly profitable.Understand Debt: Taking on $500,000+ in debt is a serious commitment.

Of course, there is very literally entities out there who make there living via filling frivolous lawsuits than offering settlements at cost savings vs one fighting to prove innocence, and they target those "marks" based on such searches.     

The property cash flows at a 15% ROI…………………..before insurance, debt service, utilities, management, vacancies, repairs, maintenance, payroll and property taxes7.

There are syndication/crowdfunding funds currently being launched now which intend to take over deals from syndicators/operators (where those same owners would otherwise have to turn the keys over to the bank).Generally the ones in trouble are those that structured too aggressively (high debt, floating rate, etc).

As you pay off the debt are you comfortable with $4M equity exposure within a single LLC?

As someone else mentioned, what I've seen a lot of in the past six months is deals that don't have the rental income to service the debt and borrowers with marginal credit.

Typically lenders for non recourse require the borrower to have a net worth that is equal or greater to the outstanding loan blance, have at least 1 year reserves for debt service and experience and or a track record.

That amount and the debt pay down that your tenants are making for you should also be added to cash flow for your ROE calculation. 

@Michelle SharkoAnswering questions in step by step fashion:- Is it a good thing to do or not is a personal finance decision and it depends on the person asking it, their risk tolerance which in part has to do with how this HELOC or line of credit works and how your personality fares relative to taking on new debt (a person more adverse to debt might have sufficient savings and temperament to pay down/back the debt versus a financially liberal person might get in over their skii's as).
