How to deal with one tenant moving out and the other staying?

[Jacob Beran]

Hey everyone!

I currently have two tenants in a unit who pay separate utilities and rent under the same lease. One tenant is moving out, while the other is staying.

I have a few questions as the lease wraps up:

- How do you deal with the security deposit when one is staying and one is leaving? Do you roll the deposit over for the tenant that renewed? Or do you just return it to both?

-  How do you assess deductions for damage in a common area such as a kitchen? 

- Do you clean the entire unit after the one tenant moves out? Or just the common areas and their bedroom? 

Thanks in advance, I’d really appreciate the help!
