As I had done before, I included a clause in the purchase agreement that I be allowed to market and show the home before taking possession.

Why is it when buying a house from the tax sale, Approximately 2-3weeks until afta auction is ONLY when I get possession?

Even though you didn't give them permission to live there, possession is what matters.

Without a doubt, exorcism is better done before there's a possession.

Your idea and contention is that even though there has been a foreclosure and new owners have taken possession, that with the amount of the investment they have to make, it goes up to the original cost?

Just make sure you are not too possessive about the property.

If they were a legal tenant and they've stayed beyond the term of the lease, that is considered a "holdover Tenant" and they need to be evicted.A squatter is someone that took possession of a property without any legal right to do so.

She complained to me she heard voices in the house and was wondering if someone died...so I wouldn't be surprised if she wants to move out due to being afraid the house is possessed.....Saying this because I wouldnt have an issue paying for the ozone rental but dont want to do it if she will end up moving out anyways...

(doing damage, causing disturbance, possession of a weapon, doing drugs, etc.)  

If they were paying you rent it would stop any adverse possession type claim but a whole other can of worms might be opened up, plus you’d need liability insurance for the playscape.
