Are you aware of some Oregon Statute or Lane County Ordinance which allows foreclosure and sale on anything besides a property tax lien by the County?  

I know that even a Property tax lien can't be foreclosed on until it is 3 years old.  

"Real property within the state of Oregon is subject to foreclosure for delinquent taxes whenever three years have elapsed from the earliest date of delinquency of taxes levied and charged thereon 
The properties not redeemed within the two-year period prescribed by (29-312.120) shall be deeded to the county by the tax collector. At that point, the county may sell the property or retain it for public use, at its discretion."

Please tell us which Oregon  Statute or Lane County Ordinance lets the County do that with a fix-it-up lien.
