The only way to know for sure is to try different ones and track your response/deal rates. 

Or should I pay for the subscription to make the screening process easier, collecting rent, tracking maintenance, etc?  

@Jacob Hicks I think you are on the right track. 

You are on track to a great start in your journey. 

However, you're on the right track.

Each one will have it's own vibe and it's own "mastermind" track. 

The only property type the county will think about rezoning to industrial from another type is one that happens to be along railroad tracks. 

More markets equals more time needed to track, meet with your team, travel to and from, tax season, etc.

@Ravi KaruturiRavi, a Project with a $10M “all in” cost will typically support a 70%-80% loan to cost (LTC).This means that you can borrow $7M-$8M which means that you will have to invest an equity infusion of $3M-$2M.More fundamentally, if you are asking a question like this, your priorities need adjusting.Raising capital from whomever, and especially from friends and family must come after you have acquired and can demonstrate the skills necessary to build a $10M ground up development.I believe that if you pursue a plan to raise the equity required that you will find it very difficult to secure bank debt without a track record and or the skills noted above.Feel free to reach out to me if you want to talk.
