So as to not seem biased and to be fair one REIA may appeal to you and your needs more then mine so my pick for the last many years may not be your pick. 

His company manages mine and has got some great properties

That's exactly how I had mine listed...a note at the bottom of the description with almost the same wording (didn't include wrist band) and that is what they said was against their policy.  

, if that was your purchase price and only put $10k to rehab , where did you find this gold mine in 2019!

I was told by an associate of mine that they were charged an additional $15,000 at closing due to a "title fee" on top of the ones you listed.

When I closed on my first duplex in Harrisburg, Pennsylvania in August 2017, "the 2% Rule" was the gold standard for determining whether a property would cash flow.  

Mine have all been in the Space Coast (Melbourne, Rockledge, Melbourne Beach and Indialantic)2.

I positioned mine near Case Western Reserve University and the hospital system, and that has been a major advantage.

The biggest focus of mine would be on just having one tax lot and maybe cheaper financing.

I remember when a close friend of mine bought his first duplex in Philly; the excitement was off the charts.Your idea to pick up the neighboring property is pretty smart, especially with that shared backyard.
