Reply @Greg H. what ifs do not matter in law. As I stated that is arkansas code, which is why I said whatever the OP uses would need to be legal for his state. My lease states what is considered abandonment and restates arkansas code in terms of abandoned property. I can reference arkansas code if you would like. I am not worried about supporting cases.
As you can see below, I give an additional 3 days notice to the tenant that arkansas law does not require of me. If your rent is past due and I have been unable to contact you for 10 days, by phone, email, at your residence, neighbors haven't seen you there, I post a nice 3 day assumption of abandonment notice stating that I will take possession of the property in 3 days under our lease agreement. Then, I can under our lease and arkansas law consider it abandoned and burn their crap in the back yard if I want to.
Bottom line it's legal here AND it is in my lease.
