Hopefully your property management team has taken the appropriate steps to provide for a refund of all of the damages in the home.
You're going to have to evict the tenant, and sue for damages. Your damages are going to consist of any back rent that the tenant has not paid, plus damages to the property. However, given that the tenant is indigent, you're not likely going to see any money from the judgment, outside of the security deposit you received upon move-in.
For section 8 tenants I demand the maximum security deposit possible, a month and 1/2 nonrefundable, governed by State law.
