Extortion in an eviction case - advise needed.

to answer bobjbklyn, the reason I didn’t insist that the building be delivered vacant is that it was an unuasual deal, and I was asking alot of patience of the seller, so I didn’t want to make waves.   The building was not listed for sale, I got to him before he had done that, via word of mouth on the street.  There is a big demand for a very low supply of buildings in this neighborhood, and I had lost other deals to all-cash offers that swooped in once I had an accepted offer.   I just didn’t want to rock the boat and cause him to put the building on the market.   As it was, the seller waited patiently for 10 months while I went from lender to lender and finally landed a loan.    I did know that I was heading for a storm, but some decent experience of friends in amicably removing tenants led me to believe that it wasn’t going to be too bad.   I was taking a chance and I don’t regret it, I just want to get through it.
