@Rich Beam your lease can't cover every possible scenario and should only focus on the most common problems.

Am I able to deduct expenses from selling the home such as realtor admin fees, advertising costs?

Meaning you add all that stuff up, and that's how many discount points you'd have to pay to get the rate you see advertised everywhere.

Looks like it needs flooring, paint, countertops, cabinet refinishing (or replacement), roof repair, dry rot repair, maybe foundation repair, lots of wall repair, and possibly plumbing/electrical repair (nothing can be seen in the photos but common in that area).I agree with @Dylan Vargas that there is no money to be made in flipping this property based on your numbers. 

They aren't common equity owners - their IRR is capped - which means it's relatively simple to handle a chunk of the what-ifs that come up. 

Employers had to demonstrate they had advertised positions locally and in the US in general, before they could make an offer to a foreigner.

I think a common misconception that people have when they initially get any sort of windfall is "How do I make this money equal financial independence for the rest of my life?"

The common thread I'm hearing so far is to take it slow and consider all of my options.  

What concerns should I be aware of that are common with duplexes?

I would advise you to look up the turn-key rental opportunities in Memphis and make that your first target (I can think of a really good one, but no ADVERTISING on BP forums!).
