The procedure was different for all three checks. 

If he wants to leave, follow your procedures to remove him.

Usually there is a holdover clause if they do not leaveUsually there is a clause if they break the lease to cover your holding costs and cost of marketing, but if they leave at the lease expiration that does not applyUsually there is a requirement that you send the deposit to the last known address (yours) assuming the tenant set up mail forwarding they will get it.I followed procedure and sent a tenant the SD to the last known address (mine) and it got sent back to me.

And proper management procedures, regardless of how many assets and equity you have.
