I am sure the previous owners put quite a bit work on it, and it possessed its uniqueness.

At that point you can take possession without an eviction. 

Some websites contain some of the information required, while others possess nothing.

i would maybe consider offering them a few hundred dollars and having them sign something agreeing to vacate and that they are not due anything else back as far as possessions go.  

If so, before or after the new owner takes possession of the Title? 

The real estate industry operates in the "Trust Economy" and trustworthiness is a possession my team and I hold dear. 

Offer flexible possession terms for the seller to get moved out, find their new home, etc. 

I recently bought a tax certificate on a property, found out it is abandoned, and am working with a lawyer to take possession of it and get clear title.

In other words, if someone has not taken lawful and exclusive possession within 6 years after the auction, then the former owner can get the property back and not have to pay the investor anything at all. 

The clauses in your contract, "right to market and assign, an automatic extension, out contingency, full profit disclosure, possession clause, expiration date and it should be in docusign format."
