Im wondering, wouldnt a way as a non-US resident to invest in real estate in the US on the same terms as US residents be as a limited partner in a syndication?  

I would check with a real estate attorney in both Arizona and Minnesota to make sure you're compliant with state specific requirements and to handle any potential tax implications.

It looks like there are other ways to verify their salary but no real way to do a background check. 

Alongside this journey, I’ve started my own car detailing company, which has given me a solid foundation in business management and customer service.

Read the book "Long Distance Real Estate Investing" by David Greene, then decide if you would like to sign up for an investor academy (which will probably cost hundreds/thousands). 

Real estate investing is a long game.I wish you all the best.

@Warren Barton  Having your property manager pay you through your LLC EIN offers better liability protection by separating personal and business assets. 

My practice area is estate and trust based planning for individuals and businesses.

I am hoping to learn a lot and find local real estate investors. 

A good private money lender should be transparent about terms and fees, have a solid track record and experience in real estate, and demonstrate flexibility in tailoring loan options to meet your needs.
