Rustic Canyon is a very good case study. I suspect that if you privately got ahold of Geoff Shackelford, you could get much of the inside story.
But as case studies go, if you are looking to document a really ideal low budget, high quality, affordable, community effort, that is privately owned as a shareholder corp, yet operates almost like a muni in some ways, Doug Wright has it correct, Wild Horse might be the mother of all case studies.
Intrastate share offering, something like $500 a share, 39 homesites on the periphery of the golf course, with an initial lot sale. Course and clubhouse reportedly constructed for <1.5million, small town citizen participation with some chores and labor donated. And, I'm not even telling you what the initiation and yearly dues and cart fees are. Although it is not an equity club. I firmly believe in some areas of flyover country, the model can be duplicated to some extent, if you can find a town and 30 mile radius area with a golf market. But, that is easier said than found.
