I say something very similar to be honest ~ the expected date for it to be returned and that failure to return it BEFORE that date will be viewed as intent for the clients desire not to renew the contract *instead of termination cause it sounds so negative* and that I will therefore begin to advertize to fill the space for January 7th 2013. Please note that if you are not intending to renew the contract for care that written letter of withdrawal is still required in order to apply your security deposit to the last two weeks of care.
