This is a techinique I do I call the stealth negotiation. I purchased a 1 acre parcel for $300. but that's not the kicker. The kicker is he purchased the lot 4 years previously for $55,000 cash. I purchased for $300 and then quickly sold it for $5600 and this was done in 2010 Recession.   

Ive done. thousands of these types of deals, so no there was no money owed on the property, no liens, no taxes either.
