These pre-construction contracts have many contractual provisions that are time sensitive for the buyer and are usually favorable to the developer.  You should always have a lawyer review any pre-construction contracts before you sign them.  In the event the developer is in breach of the contract, you must look at the remedies in the contract.  The contract will provide what remedies are available to the buyer and what happens to the deposit.  There may also be other statutory and common law remedies available to you.
