How to break a lease?

[Samuel Fletcher Hardy]

Hey guys,
I have a tenant that has asked to be let out of his lease, I am ok with it because he is consistently on rent and has broke 3 of his 4 windows in his apt. He agreed to forfeit his deposit in order to pay this months rent/late fees, and to replace the most recent window. I have not walked the unit yet but I'm sure there is more problems as well inside to for me and him to discuss. While i have the leverage of his deposit and him on the lease is there away to address other damages? I am sure he smoked weed inside the unit. also I know I need to document the lease break but I am not sure how.

Thank you for taking the time to read all this guys!
