Develop a profitable and sustainable business plan and learn how to sell it.

Ideally whatever formula I work out will be scalable and I can do some more deals with other friends. 

I’m looking to network with developers who have worked on similar projects.

I am a developer and GC in charlotte.

@Amy DeCesare While the areas you mention could certainly benefit from more multi-family units, generally people in the more affluent parts of the state like Washington county oppose such new development, either indirectly through zoning ordinances like minimum lot size and parking requirements that make it almost impossible to build (as @Brandon Ingegneri mentioned), or directly at zoning hearings where neighbors show up and oppose it because that they don't want to change the "character" of their neighborhood.It can be done, but it's far more the exception than the rule and requires big bucks, political savviness, and the ability to make a big bet and absorb the loss if you lose.

The piece I wanted went higher than I wanted to pay, but then that was bounced by a developer who bought all 30 acres plus the house.

Just to add a few more ideas, you could consider selling it with security system if the area is not ideal, the basic package for simplysafe is like $200 and from my experience people really love it (at least in my rental property). 

I need to develop a team to punch out a similar deal.  

It's a fully developed town and all but it's a little run down. 

You describe it as a C property in a B neighborhood which is ideal for a repositioning and raise rents.
