Time and time again I receive requests from buyers to get the keys at the final walk through. Granted, the closing is usually the next morning, but yet, you don't own this property yet. The owner has every right to still enter and occupy this home until it is closed and they deserve the privacy to do so. Now some buyers beg and plead and make promises that they won't enter the property until the morning, but no offense I can't trust you. Not that you aren't trustworthy, but the pressure will get to you and before you know there you stand the night before closing inserting key into door knob.
Early on as a Real Estate agent I let a couple of people have keys early who swore on the lives of their children that they would not go into the property before they owned it. The last time I gave a key to a buyer early, they started to move in before they owned the property. I drove by about 2 hours after the final walk through to find a moving truck out front and everything moved in. On another occasion I found the buyer and their whole family (20+ people) wandering around the home before they owned it. Needless to say I have learned my lesson the hard way.
Now Mr. and Mrs. Buyer, don't take it personal. It is my job to protect the seller's property until it transfers ownership. Also the seller is responsible for this property up until closing. If some should fall and get injured or something got broken the seller would be responsible. That is not a chance I can take
I know you will plead, beg and promise, but believe, me once you have that key in your hand it will be all you can do not to resist the urge to just take a peek. Who will know? Before you know it that evil voice in your head has convinced you its okay. So to protect you from your self, I cannot give you the key early.
Don't take it personal.
