@Mindy JensenI had one started back in January in Florida and the judge issued the writ of possession but Sheriff called me to say that they could not post it.

Once possession is taken, the fee becomes the security deposit.   

Are you versed on legal issues, and do you possess or can you learn the people skills to deal with difficult situations?

Moving in and taking possession would also indicate that you consider yourself the owner, and the recording of the deed is just a minor technicality.Unless the addendum says something differently?

The tenant has kept possession of your house and is stealing from you.

The lease with the tenant states that the property is pest and rodent free at possession and that in the case that there is an issue with pest or rodents in the future the tenant would be responsible for taking care of the issue.

@Kenneth Garrett The move in fee is increasingly popular in the City of Chicago because of its punishing CLTO and the potential penalties for not following the rules re: security deposits.I personally like a move-in fee (at half-month's rent) because it guarantees me $ for things like repainting and minor repairs between tenants that wouldn't otherwise be able to be deducted from the security deposit but always need done.Downside is it is less money in your possession if something major happens.

I recently bought a duplex and one of the units will be vacant on possession.

And the "inflation" update to that is; "within 36-48mnths of possession". 

A tax lien gives you the right to immediate possession (rents) of the property in Alabama.
