Does a 60 day notice from seller transfer to new buyer

[Sarah Miller]

Hello. We are currently in escrow to close on our first flip investment property. Seller wanted a quick close. She gave her tenants a 60 day notice to vacate and they should be moving out June 1. We are set to close escrow on 5/16. What if they don't move out? Do we have to serve another 60 day notice? Or does her notice transfer to us? We are in California. Thanks for any advice.
