What I'm finding is have to stay active in submitting offers .

The MLS will show active available rentals you'd be competing with and rented properties showing exactly what the owner/landlord received on the lease.  

Lots to consider here depending on date purchased, how it was split, what is being built, and when it is placed into service.

I looked into PM services, and based on my calculations, 25% of my net cash flow is going towards PM (factoring their initial 75% one-time setup fee and 8% management).Also, there are no 1-bedroom apartments or condos in the block - only 1+ bedrooms available - not for rent but none present.

Thank you for your Service!   

There is a STR group in Atlanta called AMSTRA stands for Atlanta Metro Short Term Rental Alliance led by @Rich Munroe, he is very active and worked very closely with the city while designing STR to present owners side of the concerns.

I would have paid another experienced local investor (an unbiased party not having anything to do with the sale of the home or selling me services) to do a thorough video tour of every inch of the house before submitting an offer. 

As in my case, working as a full service Property Manager, I'd imagine that would instill more confidence that a building will be taken care of, units will be leased, preventative maintenance will be done, etc.

Ironically when I first hired them their service was quite good. 

I understand the above services are not free and so willing to pay for it and also open to be fingerprinted.
