I would certainly at the very least get a property manager, the idea of using a resident manager is also one that has had success but I would make sure you really trust, think of them essentially as a partner in your business seen as their choices and decisions directly impact your business and investment (pick someone that is responsible) another part of your team I think would be vital to your success is a handyman that you trust, someone that can handle small repairs quickly and be trustworthy and knowledgeable enough to know when the task is outside their ability and can let you know, the manager know to contact an actual specialized contractor or if you trust them enough allow them to arrange and coordinate the hiring of contractors.Obviously I would definitely consult with an attorney and get a contract drafted up for each of the people on your team so there is no questions as to who is responsible for what. 

You have to sign an FHA addendum specifically staing you will sell the home for the contract price only and there will be no other agreements or arrangements.

The key is to be able to detect that the borrower is late and arrange for a sale prior to the default notice.

It looks like most of the duplexes that I am seeing will mean down sizing my family's living arrangements.

The tenant’s daughter, who is in adult that lives in Detroit, has moved into the unit and is now illegally occupying the unit while trying to figure out how to move forward with arrangements for her mother.

Yes, the owners should be paying, otherwise you have someone else's junk sitting on your property (which is somewhere between littering and squatting).IF possible, I'd recommend serving the non-paying owners notice ASAP that lot rent will be established on X date (some day near enough in the future to be prudent, but far enough out to give them real notice and allow them to arrange a haul-off if needed). 

Also give required (here it's 24 hours) notice and inspect/show the place as needed (I'd try to arrange it when you know they won't be home).

Collecting funds for the road has been a struggle and some believe that they're not legally obligated to participate in this informal arrangement. 

I will end this post with what I stated in the beginning; this is a fairly complex arrangement that needs counsel and oversight from a CPA (and possibly an attorney) specializing in SDIRAs. 

@Chu L.It looks like your 2020 return will be more complex than in normal years.Living in two different states may require the filing of part-year returns in each state.Hopefully acquiring rental properties increases to your cash-flow and wealth but does not increase your tax burden.Regarding gifts from overseas - It depends on the arrangement that you have.
