After my recent change in my lifestyle however, I've understood that I desire to get back to the US and continue to change my life.

Mentors generally have and continue to make their career as Real Estate Investors, not as Info Peddlers. 

Also, there are websites that offer inherited trust records or probate cases;  how do these companies access these records in all counties and be continuously updated with new cases/inheritance? 

For me making a few phone calls to verify references is not that time consuming, but I can see how it could be if my portfolio continues to expand.

I was imagining a scenario where I had a 30 year fixed term loan on it and then could continue to ride that loan while seller financing but I understand now that would not be possible for the reasons @Aaron Smith and @Russell Brazil mentioned.

Some of the advantages I see are access to the MLS, ability to see properties quicker and make offers quicker, and the opportunity for continuing education. 

The article gets one thing right: Landlords are suffering at the hands of tenants that continually make bad choices.

@Step SthephYou may also want to think about holding onto the property that you live in in your own name for now.You are eligible to exclude up to 250,000(500,000 if married filing jointly) as long as you lived and owned the property for 2 out of 5 years.If you transfer the title to an LLC - you may lose out on the appreciation as you continue to live in it.You have a couple options regarding the other lots.If you don't know contacts or how to develop land - you may want to consider the land outright.If you have experience to develop land - you may want to pursue developing the land and then selling it.option 2 will likely generate more money but also require more work.

I have and will continue to do my own independent research, but any advice from personal experience would be very much appreciated!

But always continue to educate yourself.
