Interested in buying at Sheriff Sale. Mitigating risk?!

[Derek Sziga]

Hi everyone, so recently I purchased my first condo as a rental  property and have instead moved in / out of my parents haha (to have our own space until we find a house).

I am currently looking at a upcoming Sheriff Sale for a home Id like to invest in.  I'm hoping I am not overlooking things and am trying to mitigate risk ;) any insight greatly appreciated. 

-I was able to see the inside of the property since the previous owner had the home listed on zillow in attempt to sell prior to the sheriff sae. ( I have a good idea of what needs to be done and how it stands on the market).

-As far as I can tell, County Recorders office shows three loans. 2004 - Loan for 223,000 , 2004 - Loan for 50,000, 2008 - Loan for 75,000

The 50k loan was "released" , 223k Loan is bringing it to auction, and the loan by Bank of America in 2008 is listed as one of the defendants on the court docket "BoA."

----Would you be held liable for the 75k loan from Bank of America after purchasing? Can someone define senior vs junior loan?

----How can I check for any other liens against the property? I see in the County Clerk two cases of unpaid credit cards. One is "case closed" and other is "Judgement / Decree". Last case is the "open case" of this foreclosure. 

----How does a Sheriff's Deed compare to something like a Warranty Deed, Quit Claim, Trustee, Executor etc.?

I am trying to learn and understand more to better guide me in future attempts at short sales. Thanks in advance to everyone's input! This sight has been nothing but informational in my real state adventures!
