BUYER 应该在第二个房子的合同拿到后，就让Realtor withdraw offer from the short sale house. Must be in writing and buyer must signs it.
一般short sale 有short sale addendum, 上面应该有一个时间限制， 例如：要求short sale bank replys in 60 days after both buyer and seller sign the contract. 如果short sale bank replied over 60 days then you have right to cancle the offer.
also short sale bank must have an approval in writing. Don't trust any verbal approval. Because your lender will require the short sale approval letter as part of your loan application if you need to borrow to buy.
