No court decision needed to have the estate get money that it is owed - the court is just going to get involved in determining where that money ends up going once it is paid into the estate.Now, what to do with belongings and possessions left behind is another matter - but the least expensive thing for the estate is to get it out of the rental unit and into a storage facility if the stuff has value and must be distributed.And you hope after the move out is done that any damages do not exceed the security deposit; otherwise, the landlord has to place a claim against the estate.

Having checks or money orders mailed to you is definitely ideal, all my storage customers do that, and 1-2 apartment tenants do that. 

Any recurring expenses (utilities, cell phone, storage unit, etc) can also count towards your alternate credit.
