Managing my own properties and building systems/processes to become the best hands on property manager will help me jump into creating my management company to where I'll be able to offer the same quality service to other investors who don't want that responsibility. 

I want to start renting it out to create some more income, and am currently looking for an additional home in the area to do the same thing.

I own a 2 family home in NYC- created and bought the house in an LLC.

Do rental properties around you create good cash flow?

Need some guidance, I am currently creating a pro forma for a possible industrial property and all of the tenants are on NNN leases.

You'll want to create a pro-forma (cash flow projection) for both the multifamily section and commercial section separately, then combine them in a summary pro-forma. 

I have created my own list.  

You may have a great deal or have the ability to create a great deal as mentioned by @Brian Ito but you need to put in a little homework up front and then take your shot from there. 

customer service is poor, and once you get added to their email list it's hard to get off of it. 

Right now I'm working on renovating hallway areas of an 8 story condo building and we will be removing (or creating) surplus materials - 8" stained/unpainted egg-and-dart crown molding, chair rails, and more than 200 light fixtures, - all in good condition.
