在某些交易中, buyers may wish to make their contracts contingent on them receiving the proceeds from the sale of their current home. In this situation, the buyer will attach the Addendum for Sale of Other Property by Buyer (TXR 1908, TREC 10-6) to the contract. While this provides the buyer with the benefit of the contingency, 作为回报, it affords the seller a benefit as well. The seller may continue to receive, 谈判, 并接受后援, which would then allow the seller to ask the first buyer to waive the contingency if a better offer is received.
When a seller receives a back-up offer with more favorable terms than the first offer, the seller must execute the second offer with the Addendum for Back-up Contract (TXR 1909, TREC 11-7) attached. 然后卖方可以使用 Notices Regarding Contingency Under Addendum for Sale of Other Property by Buyer (TXR 1912) to notify the first buyer of the accepted back-up offer and to allow the first buyer to either waive the contingency or terminate the transaction. Just because the seller has received a back-up offer does not give the seller the ability to ask the first buyer to waive the contingency.
