Steps required to acquire tax lien multi family properties?

[Kenneth Rogers]

I am currently taking advantage of the marketplace tool here on the BP website for finding foreclosures and I've come across some multi family properties in my particular area, Akron/Canton region in Ohio, that show tax lien beside them. I am wondering what would be the necessary steps to pursue such a possible opportunity? Also, are there certain negotiation tactics that could be utilized when coming up with a purchase price? I am still looking to buy my first buy and hold as an owner occupant.
