Offering on foreclosure, guy still living in house

[John Ewas]

I'm going to put an offer in on a foreclosed house. Foreclosed 12/2012. Original owner went belly up, he then got some money from a private investor, 42k mortgage, then got a Hard money lender, to lend him $132k. That went belly up 12/2013. He's still living in the house, HML doesn;t want to evict ? I door knocked, he was on the front porch before I got out of my car. Wouldn't let me look inside. Told me conflicting stories, he was never served, post office screwed up,, etc. He did say that if I gave him 100k and paid off the $200k mortgage it would be mine, lol He;s been living there rent free for 3 years now. He has a job. Whats the most effective way to get him out ? How long does eviction take in liberal Mass ? I was thinking of giving it to a biker group, providing them with 10 kegs of beer and telling them to have at it. Or I could just move in with him with a few friends.

thanks
