HELP!! is this Normal or Abnormal? Seller stays after closing?

[Rhondalette W.]

The day has finally arrived. We have been waiting for weeks to get mortgage approval for our first rental property and will close on tomorrow.  I have the cashiers check for the down payment and I am ready to go to title company tomorrow, however, my Realtor informs me that we will not actually get the keys tomorrow because the owner requested a few days "5" days to pack and move. Is this normal??  Originally, the Realtor said the owner wanted to lease back the property after closing but then she explained that there is no money involved in a lease back but it is a courtesy to allow time for owner to move. 

No keys?  and No money on a lease back? Is this normal?
