Reducing or removing liens

[Kelly Maestri]

I'm buying my first bankruptcy/foreclosure in Portland OR PDX and it has a # of liens on it. Specifically, an $89K fire department lien.  

Has anyone had any success getting liens reduced or removed?  The bankruptcy trustee is going to try to negotiate with the city starting at 50% and has asked the real estate agent to work with the city. She's left some messages but has had no response.  I'd like to jump in and see what I can do.

Any suggestions or past experience?  Thank you!
