Hi @Wfrail 

These steps should help.

Leave a device for the next resident
To give a device to another person, follow the instructions below. If you have a Nest Aware subscription, make sure you cancel your subscription

Open the Google Home app .
Tap your device's tile.
Tap Settings and then Remove device and then Remove.​
Perform a factory reset. A factory reset will reset your thermostat, doorbell, or camera to its default factory settings.
Note: This action will clear your data from the device and can't be undone.
