Tenant Belongings Left Back

[Eric Vasilopoulos]

Hi all, I recently purchased a 4-plex in Queens, New York area. An inherited tenant from one apartment just moved out and took all of her belongings from the apartment, I used cash for keys. She took 3 months to move and was not paying any rent. However there are multiple belongings left behind in the basement which is not part of her apartment. I assume since this is a public space, the rules of giving a notice to pick up those belongings does not apply? 

In addition, I did have her sign a surrender of premises agreement when she moved stating that she has already moved out including all of her belongings from the apartment and has no further interest or seeks on occupying the apartment. Not sure if this helps in any way with the basement.
