 But there must be "some" specific payment listed in the contract, or the contract will be considered void for lack of consideration.So the contract may be written to reflect that the house is being sold in return for "ten dollars and other good and valuable consideration".The ten dollars is the "peppercorn" that provides concrete consideration and ensures that the contract is valid, while the actual amount paid for the house is hidden and referred to only as the "other good and valuable consideration".
