You offer the occupant a payment (typically no more than 1% of the value of the house but it's up to you and what the occupant will take) in exchange for him to voluntarily give up possession of the property.

.), so I just want to have $1M in my possession by then, cash or net worth. 

@Dennis Lanni What is the adverse possession options?

... or risk losing it and your properties - AND personal assets/possessions -  in litigation?

You obviously need to take possession of the property so you should have a real estate investor friendly attorney take a look at any language you add to your PA and make sure you are at full transparency. 

We have a very large population over 70 years of age that possess a lot of real estate.

@Mike McCarthyThe rent allocation between the vendor and purchaser is an adjustment made at the time of Close based upon the day of the month the purchaser takes possession.

So many properties that went to Sheriff Sale, prior to the change in stance by the PA Department of Revenue, with deceased borrowers where no probate was ever filed, are now in the possession of new owners who have no idea of this silent lien occurring and being in place on their property. 

Would there be additional filing requirements for the LLC taking possession of a property in LA?

I am hopefully in the last stages of eviction through my PM's attorney-hopefully I will get possession next week.
