And there's a 147 unit section 8 apt complex being developed as well - in an "affordable" area. 

Quote from @Rob Williams: Hi everyone,I’m looking for advice on effective ways to connect with private investors locally interested in senior living land development.

Long term it will be prime development land for residential and/or commercial, whether it is us to develop or sell to a developer.... we may subdivide and sell some of it in the short term, so we don't wish to erect structures or change zoning to make development harder down the road.   

Unlike you, I've read multiple self development books but different fields.

Battery technology is evolving FAST now because companies know there are serious opportunities if they develop the technologies.

Note that I am also a real estate agent as well as an investor/builder/developer, so I have multiple ways to monetize a postcard response. 

Have a ton of experience in the rental market, and ground up development including industrial and retail.  

Hopefully you know some local fellow investors, but if not, certainly developing this local network is important and would put an emphasis on that as well.   

When ANY information or development, good or bad becomes known to us about a deal we are invested in, within 48 hours we send an email to each investor invested in that deal, as well as post it on our investors only portion of our platform.

I know many developers like yourself with the same issue ("trapped" equity they can't access unless they sell the property).
