Looking at possible Sheriffs Auction Duplex

[Jeff Kieszkowski]

So on Auction site they listed a Duplex that is 3 doors down from my in-laws. It is a small 2 bed 1 bath on each side at 1400 sqft. What should I look for when it comes to the title. They do list the title on the site and it shows no liens but is that all I need to be concerned with. Is there something else I need to look up because  what they have listed wont show it to me.  There is also the unknown stuff like what the inside looks like and how good the current tenants are. I was thinking of going in for 10K-12K max bid. For this price I can handle a lot of unknowns. I am sure it will go higher during the bidding process but if I get lucky it could be a great start.
