I recently scoured the web for videos of his exorbitant training sessions to see if the "insider secrets" his Rich Dad company touts to possess really justifies a 5 figure price tag.

Neither of which are things you currently possess. 

PossessionSeller shall surrender possession to the property at closing, buyer shall withhold proceeds from the sale in the amount of $______________ as security.

The daughter had 3 prior evictions which I found after I got her name, mom had 0 until this one (both were named because the mother was on the lease and the daughter was in possession).  

And then you need rights of possession.

This idea, also coincides with possession.  

My end lessee is required to possess a renter’s insurance policy, while the owner updates their current policy to a “landlord insurance policy”.

Try to get something in writing from her that says she is voluntarily releasing possession and returning possession to you, with any pre-paid rents remaining with the landlord as consideration for early lease termination.

You can not take possession of the money.

I'm assuming you are talking about doing this after you close on the property or have it under your possession otherwise you've got lots of legal issues there.In my experience I wouldn't hire someone off Craigslist for that.
