No, they aren’t. That “buying an entire neighborhood in a single transaction” thing is misleading. It was designed from the very beginning to be sold in a single transaction, much like apartment towers in the city are designed, built, and then sold. A “normal” housing development sells individual houses one at a time, usually far in advance of the house being built. You can’t sell the whole thing at once unless you planned to do that at the very beginning of the project.
