Self Financing for our Homestead Community

I am part of an Intentional Community in Bucks County,Pa. (Bryn Gweled Homesteads, Inc.)
We are hoping to pursue self financing so folks that want to buy homes don’t have to be held hostage to Banks. Are there communities out there that are doing this?
We do not own our land and therefore are turned away when we try to borrow from ‘tradional banks’.
