Verifying last 2 years of rental history very important!

I'm looking to sell my first home, which I've been renting out for the last 2 1/2 years -- I first contacted my property management company  for seller services, and they initially wanted a year exclusive selling rights.

I'm gonna need someone that does all in house, Blueprints to the last nail & finish. 

I had to redo a bathroom last year in a 2/1 in an occupied duplex I own and I spent $6,004 in labor and materials (10% off at HD/Lowes as a veteran, just didn’t do flooring and left the old vanity, doesn’t include the damage the leak did in the lower unit). 

One appraised last year for 100k.

My experience is on the finance side of Section 8 rentals - I helped one of my clients last year do an 80% cash out refi on 40 units in KC (20 were S8) where he cashed out seven figures. 

Have been talking about getting into real estate investing for the last 2-3 years and finally pulled the trigger on a 3 unit house hack in Soulard that will be closing later this month and will be self-managing the property.I'm trying to network a bit with other investors, build a solid team of contractors / handymen, and set my systems up in way to scale, but also so my tenants have a good experience.

Quote from @Robert B Azimi: A restaurant that’s doing great business feels he shouldn’t pay the rent on time for the last 4 months every month we had to post 3 day notice to pay  rent or quit on his front door for him to deign to pay his rent What legal action we could take to make him understand he is not the landlord we are he must pay his rent on time?

I have lived in Arkansas my whole life, lived in all parts of the state, and have been in real estate for the last 8 years here. 

Maybe if I was younger it would make more sense, but staying with the method I've used over the last 10 years will only become more refined and efficient.
