I have used Block & Associates with my (single family) units and they have been fantastic.I'd probably recommend Park Avenue Properties for such a large complex.

I don't have access to the MLS ( multiple listing service ) in MD.

There is no internet access at these places.

Installation and site access for these are another big issue. 

Perhaps a few blocks out of the area.

You are right it is great having 24/7 access to people that have done it successfully but there is so much to learn from this community as well!  

Com company but after people in Illinois area connected to me on linked in they blocked me. 

- Any market can be good for flips if you've got some skills, good subs, a little cash, access to credit, and some knowledge about the market.

The building is concrete block and previous owners built on the side of it another "Wooden frame" store front which is "attached".Each unit is being rented out under market value, and decent condition.The property does not have a CO (calling town this week) but is in working condition and fully rented out. which is strange?

Build a network of wholesellers, RE agents, attorneys, etc. that may have access to deals and would bring them to you 1st based on your relationship and incentive structure.
