Help us buy a summer camp!

[Jeff Macdonald]

My wife and our closest friends all met at a summer camp in California. A camp next door to ours is now for sale, and we are considering buying it together as a part communal vacation site and part wedding/vacation rental. There are 10-20 potential buyers in our group, and the cost is just under a million. What are our financing and legal entity options? Word on the street is the owner is ill, so that might effect owner finance options. All related advice/resources welcomed!
