It is not unusual to sell a home and buy another and end up closing on both on the same day while moving out of one and into another. It happens all the time and it usually works out. It can get really complicated if the home you are selling is being purchased by someone who is also selling their home.
Possession is generally written into the contract and it is best if the new owners get possession immediately after the closing but that isn’t always possible. It is especially important that parties communicate with each other and work out compromises. It is also a good idea to avoid using phrases like “you must” or ” I have to have”.
There really is no “must”. Both parties need to agree.
