I am sure other landlords would appreciate your diligence, but you have to be careful here as you don't want to run afoul of credit reporting laws. You may be able to get the debt onto her credit report by assigning it to a collection agency, although they usually take a substantial portion of any amount they collect as a fee. (That may not matter, though, as she's probably pretty much uncollectable.) Sometimes they, also, want a judgment first.
