You can still appeal assessments on ANY property if you can show the board that your home is over-assessed. They use a figure called a common level ratio which gives the proportion of marke value that assessments are derived from. They may ask you to obtain an appraisal from a certified appraiser. Assessments must be appealed by September for the upcoming year. Bear in mind you cannot appeal the taxes - you appeal the amount of the assessment.

I see you were asking about new construction in your prior post. I wouldn't call the number "typical" as you say, but yes it could conceivably be $6K depending on the assessment of the property. New construction does tend to be higher than resales initially.
Yes, you can appeal your tax assessment. It's a fairly easy process.
