This way if she doesn’t pay for the storage space, you can lock them out and then confiscate and auction off the contents, like a storage space does, to recoup your rental cost, (note: anything acquired over and above rental income and fees to recoup is required to be given to the tenant) without having any connection to the rental of the home, and without having to go through the standard eviction process -  (read your state laws on storage space rental rights, they can vary from state to state on times and rules) but in California you can rent a garage as a storage room.

I see it for what it is; wealth confiscation.

The day of close, the tenant on one side was arrested and his 80 lbs of marijuana (illegal in Indiana) was confiscated.

The DEA kick the doors in ripped all cameras, alarm, controlled access off confiscated everything out of the building put holes in the walls.

I do have pics taken from my monitoring system but I don't know if that's enough if it doesn't capture then confiscating the item.

Do both parties must agree before we can confiscate the deposit?  

You don't want to buy anything that you can't have in your possession (think FDR when the govt confiscated gold).

I'd hate to see you lose your first rental property, confiscated by law enforcement!

So he deserved to have SWAT break down his door and confiscate all of his legally owned guns because he made an error in judgment?

If you get caught the police can confiscate this whole place from me - and I'm not interested in having that happen to me.
