CONGRATULATIONS! Possession day is around the corner!
Last touches - leave the garage door opener and any access codes/cards behind for the new owners. A note describing any small nuances accompanied by a bottle of wine might be a nice touch.
You can hand the keys to the buyer or give them to your lawyer to release when everything is confirmed. If you are out of town, you could also consider using a lock box and provide the code to the new owners.
Congratulations – What’s for dinner? Where are we celebrating?! Great job - you’ve sold your home on your own and kept all that hard earned equity!
