I won the judgement for possession yesterday - now patiently waiting for the automatic 10-day appeal period to expire to file the writ.  

If so,  did you ask the court for possession and rent owed ?

Or the elements damaging their possessions in the basement.

Maybe she left all her worldly possessions to her favorite charity and none of her relatives are entitled to the security deposit.

He is right, the title is clear, but that is not the issue.I would start eviction as there are two units and you need to know who is there and regain possession of at least one of the units to start renovations and get some money coming in.

Landlord may recover possession of the premises by summary proceedings when Tenant holds over the premises for 24 hours after service of a written demand for possession for termination of this Lease under this provision.

If the tenant has lived in more than two places within a two year period, it may indicate instability so I would require a previous landlord reference and make sure he actually owned the property.Whether or not the tenant's current or former landlords release information, we landlords are responsible for who we allow possession to our properties.Hope this helps!

It also makes it one step easier to evict them (if that becomes an issue) than with a standard lease agreement.Regarding your tenants, just have them sign your new rental agreement the moment you take possession. 

Not for their personal possessions but for the damage they caused.

What professional tenants are after is possession of your property and they are prepared to pay to get it.
