In 2013, Jack and Shirley Wright moved from Riverside, in Southern California, up to Santa Clara, in Northern California, when Jack's company opened a new branch office there. They decided to rent for a while so they could get to know the area before buying a home. Three weeks ago, they finally found and put a contract on a lovely 3-bedroom ranch, and the sellers accepted the first offer. They took that as a good sign, but now it's only 5 days until the close of escrow and they still haven't signed the escrow papers yet. In fact, they aren't due to sign the escrow papers until the day before the actual close of escrow. The Wrights are under the impression that something is wrong, because when they sold their last home, the escrow instructions had to be signed by both parties to the transaction immediately after they all signed the purchase agreement--about 60 days ahead of the actual close of escrow date. Which of the following is true of this situation?
