Hello Theleinus, at this point in your transaction, you should have already performed a home inspection to uncover any problems. Everything you want, they way you want it to be should also have been written into your initial purchase contract/offer. Have you received formal short sale approval (from the lienholder(s) in writing? Bottom line, whether or not you can cancel, request withholdings, etc. depends on how your contract is written. Have you consulted the real estate agent that wrote the offer for you?
