Housing is so bad right now, home builders are cancelling contracts with buyers so they can sell the house for much higher than the original contract with the buyers. For example, you sign a contract with a builder to build a house for $200,000. During the process of the build, the market value of that house goes up to $300,000. The builder may have something written into the contract to let them out for almost any reason so they cancel the contract and list the house for $300,000.
