Because of the variable of waiting for the county to confirm recordation, this can make scheduling the movers a little more difficult. The very best way to handle this is to treat this almost as if it’s an out of state move. For sellers, its best to have everything fully packed and in the truck the day before closing. Schedule a “broom cleaning” either the night before or the morning of. Then when recording confirmation occurs, the seller is already out, and the property is fresh and ready for buyers to move in.
For Buyers, you should prepare for move in after recording confirmation. This most easily can be obtained by scheduling your movers for the day after closing, or having a moving company that is able to proceed on standby. All real estate transactions in the State of Arizona are conducted this way so most moving companies should be aware of the process. If either party is conducting a coinciding closing (which means they are selling or buying another home on the same day) then loading up the moving truck the day before and staying in a hotel the night before closing is the best way to go. Make a little exciting staycation out of the process, now on the morning of closing instead of starting your drive out of state, you're simply driving across town and moving in to your new house as soon as you receive that confirmation.
It’s perfectly acceptable for both parties to communicate each others plans and goals to coordinate appropriately on closing day. The biggest thing to understand is the risks involved if either party creates post possession (which means the sellers stay after closing) or if the buyers create a prepossession (which means the buyers move in prior to closing). This creates a lot of grey area and reason for issues. If for some reason the loan falls through or there is damage to the property prior to closing, someone gets injured while the other owns the property, or if the sellers damage the property after closing. These situations are something many do try everything they can to avoid, however the real world is not always black and white. Make sure to coordinate properly with both parties and consult with a real estate attorney if you are considering a pre or post possession.
