I also use them during vacancy turnovers since those turnovers are fully automated, self-serve showings, but you have to have a way to ensure batteries get swapped out regularly, then run a separate cellular network to push updates to the locks over time, which is a another added cost.

I would build the cost of cleaning carpets between tenants into the cost of the one year lease, put in an early termination fee of X amount to cover reconditioning and vacancy time if they stay less than a year, and make the deposit just that, a security deposit.

It also has a 24-hour battery backup with a warning when it loses power.
