Flexibility: The ability to roll with the punches. - den Boer dictionary
In Real Estate I find that the ability to remain flexible can payoff in less anxiety and craziness. I have had 2 recent closings delayed, on multiple times, because of lender issues. However, delays can come from any direction. The key as an agent involved in the transaction is to remain calm and work through whatever the issue is.
Luckily, I can't remember more than one or two deals ever having completely fallen apart. Most of the time paperwork gets done that moves the closing date just enough for the lender to catch up. Issues can and do arise when a buyer has their belongings packed in a truck ready to move in and there is a delay causing a local hotel to rent a room or two to the frustrated soon to be owners.
Sellers also can be upset when they are set to close on their next home and their current closing is delayed. I have seen this domino through multiple deals, causing much frustration.
So, knowing that delays happen, everyone just take a deep breath and know that the skilled agents will do their best to make everything all work out.
