That is may be one of the turnoffs which may come across as the price is too high.Get the tenants out in two weeks, spiff it up, clean and you will probably have more interest.Feedback from the agent has been that folks express interest in making an offer but then disappear. 

To answer your last question, self management is possible but most people have no idea how difficult it is to self manage a truly successful STR with 60-70% occupancy.

Do your self a favor and use anyone else in the detroit area for your properties.

I BELIEVE it’s just a sticking point not a prohibited one like it is with self directed Ira’s.

Another way of thinking about this is self-managing your property; you wouldn't report "management fees" in expenses and then have that portion in "self-employment" income. 

I was looking at going the self-managing route due to me having a little more experience and mainly finding a great handy-man and GC in the area to help me if repairs were to come up from the tenant.

It looks like a lot of the owners use an outside PM or self-manage from what I can tell on Airbnb. 

My thought ahead of time was similar to you “I want to try these” - thinking I could self install islands of carpet in bedrooms myself and have the ability to patch if needed between tenants.

and worry about their own self employment taxes, insurance, etc.

House hacking is a great way to get started in real estate, especially if you are handy, that will be a big help.Buy a 4 plex and rent 3 units and use one for your self.
