tenant left in middle of lease

[Jimmy S.]

Hello

Tenant left in the middle of the lease. Do I need to send them a letter that I will be keeping the last month rent security deposit since they abandoned the property in the middle of the lease. It clearly states this in the lease. I never had someone leave in the middle of the without terminating the lease. They told me 5 days ahead of time and just packed everything up and left.

Does this apply like an "itemized list of damages would"  that I would need to send them if there was damaged but do I need to send them a letter that I will keeping last month and security deposit to due abandoning the property?
