How Could This Deal Work?

I have a distressed property in my area that i am interested in purchasing as a fixer upper. Here is the rundown: List Price:$69K ( but could be bought way below LP) Back Liens:$15k Street Assesment: $2,500 Prop. Value:$85k the property has been on the market since May '04. I have spoken to the realtor and they are looking at all offfers. How could i make this deal work w/ no down payment or w/ as little money down as possible?
