We are in the process of buying two contracts. On the second contract, I followed up with the broker and title company two weeks after we got closing docs because we too were waiting until they received the seller docs before we wired. They checked the tracking number and said they were scheduled to be delivered the next day. Our bank suggests having an appointment to do a wire transfer so we set one up for the next day (which was a Friday). That afternoon I called the title company to confirm they had received the FedEx packet - they confirmed receipt but our actual closing agent had already left for the day so I knew there was a possibility that something might be missing or done incorrectly, etc. BUT since they did get them back we went ahead with the wire transfer. Everything went smoothly, no problems with the paperwork and we officially closed on Tuesday. In our case, though, we only had one seller so I didn’t have the added complication of waiting for multiple people to sign or anything like that.
