Significant benefits are the marketing and management. 

Do you have a team built in any other markets?

Generally I look for distressed, development, value add, etc.  

I was wondering if most wholesalers have stopped using direct mail and just moved to google/facebook to find deals?

I think you have a good plan, BRRRR is still a great route in the current market, and especially for the states you are already in - both Indiana and Georgia are very well positioned for BRRRR deals in my view / experience

I'm an experienced builder and developer looking to network with other developers, investors, and syndicators. 

I have purchased an off-market property from an investor who now wants to sell the rest of his portfolio.

At a minimum, having viable plans in place for development will make these lots more marketable and valuable to potential builders when we have conversations. 

Did you figure in the cost of the other tenant paying less than market rent until you can get them up to market rent or replace them with another tenant and how long that will take?

Wonder what they charge developers to access their capital resources.
