It sounds to me you are looking at the value of the property. Sometimes a value is listed as "assessor's value" Especially when Trulia or Zillow are listing values of a property. Where they get their valuations is sometimes put at the site where their information came from.
Also on some foreclosure or sheriff sales sites will show taxes due Status: assessor meaning to call the assessor for status of payoffs. Some foreclosure sites will list the property this way.
As far as "status" I have never seen an assessor status as a listing status. That doesn't mean it does not exist, but in all my years I have never seen this. I would be interested in knowing more.
If you like more help just ask!
Hope we all were able to help you in some way. Re-look at the listing and get to us.
