I don't think this will matter.  

My experience in life leads me to believe that no matter how much I pay to the "best and brightest" attorney I can find, the reality is that some bureaucrat will find a flaw if they want to.  

Also, being new myself, I find I have more confidence being able to physically see the property & attend REI meetings in the area I'm interested.I'm sure you're knowledge will come in handy no matter where you go.

Always do transfers through an escrow agent in the US (or Canada or Europe for that matter, depending on where you are based), who knows business in Mexico: never release any money, unless all documents, title, property clearing is in place.

Doesn't matter what direction.

At least get assistance from an accountant familiar with such matters.

@Eric RosnerAs a matter of fact, yes I am.

Yes, sometimes there are reasons the houses aren't moving, but a lot of times the reasons don't matter to me as a landlord.  

@Jon Holdman  having had to foreclose unfortunately on my share of borrowers during the crash I got educated in the small print where my first 25 years or so lending I never even read the small print.. its when things go wonky that the small print matters  :)

Being nice doesn't matter run a business!
