Need advice with sheriff's sale purchasing

[Zachary Myers]

Hello everyone! First time poster but I've been all over the forum and love reading/learning about everything real estate! 

Long story short is I have some capital saved and I'm ready to invest in my first rental property. Recently a home near mine has popped up on zillow as an auction at sheriff's sale for Jan 19th. It fits all my criteria and from the outside looks solid but it's occupied so I can't go in. I know there is always risk involved with liens and title issues. Can someone please offer some advice on the subject of title company or attorney for the search along with cost of said search? Also just general advice on purchasing at a sheriff's sale. I'm obviously a newbie and would appreciate any and all help! 

Thank you in advance!
