How tenants prefer to communicate has been changing in recent years.  

Account Closed you most likely have up to 30 days to communicate with your tenant on what damages you found and how much they cost and 45 days to return the balance of the security deposit or let them know what they owe you, but that depends on your lease and your state.

Energy efficiency can be a big deal as well.
