Bidding on auction.com occupied property

[Steve E.]

Hello all,
I am watching this property and the status is occupied, the listing says do not disturb the tenant. Also no title insurance is offered at closing. It is a reo but then I did a title search by the last owner and it came out clear. The house had been foreclosed in 2009 and I drove by it and verified people are still living in it. After foreclosure how come the bank did not evict for such a long time. The comps shows this property at around $320K and the bidding started at $99K and currently at $154K. The reserve has not been reached. I have couple of buyers in mind I can wholesale this.
What do you all think? I am pretty new to auctions and foreclosures. I am worried about the condition of the property and what will it take to evict the current occupants? With these unknowns how much max should I bid?
Thanks
