Terms of possession should be clearly spelled out in the purchase agreement.
Best of luck!
In most cases it is three days after close of escrow.
Once you record (officially close) you have three days from that date to hand the keys over.
Best of Luck to you!

But always wait until recording.
You can give the keys, remotes and any other items to your agent. Once the loan has funded, then escrow waits for confirmation from Title that's it's been recorded at the County. Once it's confirmed, it's legally the new buyers home.
Best of luck.

In CA, the most conservative time to transfer access to the property via the transfer of keys is once RECORDATION at the County Recorder's Office has been CONFIRMED by ESCROW.
