Form a religion that promises people everlasting life if they do what you tell them. Self appoint yourself as god's spokesman. convince your members that they need to contribute money and years of time to build a high class lake front resort for "god's work". Tell them that when they do contribute time, money, and energy that they are making God happy. They feel fulfilled and you get your resort at no cost. Convince them that the project is necessary and proves that god is behind the effort. God needs volleyball courts, swimming pools, tennis courts, and a sauna.
Sell the development for a massive profit and then start over at another location in 20 years.
