Pick one, but pull the trigger.

If you’ve yet to build up substantial credit in the U.S. you can apply for foreign national specific loans that don’t take credit history into consideration when qualifying as in some circumstances you can get better rates and terms applying as a FN when your U.S. based credit history is in it’s infancy.

You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.

@Claude Diehl Selling a Solo 401(k)-owned property with owner financing is legal but involves compliance considerations.

I guess it triggers the "sunken cost fallacy" part of their brain.

If I find a deal on an area I would consider living when I move back I would like to be able to pull the trigger and possibly refinance into an owner-occupier loan once I move back to the US.  

Many people don't realize that you gain as much or more net worth through debt pay-down, and while it's less liquid than cash flow, over a 5-10 yr hold period it's considerable if you buy in the right areas with the right asset class.

There are other ways to legally raise capital, however, they have some inherent disadvantages making them considerably less desirable for what you’re trying to do.   

It's clear there are many paths to success in this market, and I hope our larger-scale project can find a way to contribute to Detroit's growth as well.Thank you for your time and consideration.

Once you do that get several bids...bids will vary considerably.
