Negotiating tax lien certificate IL

[Stephen R.]

I'm looking at a property that has outstanding taxes due. They have been sold by the county treasurer. I do have the name of the certificate owner. I'm looking for advice on negotiating the price. Is that even possible or do I contact the purchaser and ask what they want to remove the lien?

And am I correct in understanding that I cannot negotiate prior to taking title? 

Note: There are Illinois properties with future redemption dates
