I strongly suggest that you work with someone that has good long term knowledge of the market and that you invest a day or two to physically tour the areas you're considering if possible before pulling the trigger. 

I saw that in some banks I'll need to have a physical address in the U.S... 

Here's how I do my due diligence:1) Portfolio matching: (takes 30 seconds per deal)a) Have an educated opinion on where I think we are in the real estate cycles (financial and physical market cycles)b) Then and only then do I pick the strategies, capital stack, and specialized asset subclasses that make sense for that opinion.

Doesn't matter if they are MLS or off-market just go and get a physical view of the inside and out of the properties.

Basically if the cost involved a physical change it counts.

I am physically disabled, was broke, and had only a year of formal education.

There is no substitute for being physically present with experienced investors.Feel free to reach out to me with any and all questions you might have about BiggerPockets, investing, or using our platform!

We were able to do this because the property was already in good physical condition and at only 1000 sq ft, the materials needed were at a much lower quantity than we would normally need.

Either way, you intend to create opportunities for financial, spiritual, physical, and intellectual growth.
