Typically, the answer is no. You have both signed a contract and must fulfill its terms. The only way out of the contract would be if the other party agreed to release you from it, if the contract allowed you to rescind it somehow, or if you sued to allow you to back out of the contract.
If I was wanting to cancel, the first thing I would do is contact the listing agent and explain why you want to cancel. Most of the time the listing agent will release you from the agreement. If they are resistant to releasing you from the agreement contact their Broker/manager and explain.
