General rate and effective rate in Milltown
New Jersey publishes two rates for every municipality. The general tax rate, $6.951 per $100 in Milltown, is the one applied to the assessed value on the bill: $300,000 assessed owes $20,853.00. The effective tax rate, $2.500 per $100, is "the general property tax adjusted by the municipality's equalization ratio", the rate on market value. Dividing one by the other puts Milltown's assessments at about 35.97% of market value, well below market value, the sign of a town that has not revalued recently; the state median is 70.02%.
The effective rate is the fairer comparison between towns. On it Milltown ranks 124th of 564, against 19th on the general rate, and sits $0.360 above the $2.140 median effective rate. At 35.97%, a $300,000 assessment corresponds to roughly $834,028 of market value.

These are assessed values, not sale prices: at 35.97% the $300,000 row is a property worth about $834,028. The last column is the difference from the same assessment at the $2.960 per $100 state median.

Appealing a Milltown assessment
New Jersey appeals go to the Middlesex County Board of Taxation. The petition is due April 1, or May 1 in a year when Milltown implemented a municipal-wide revaluation or reassessment (NJ Division of Taxation). Property assessed above $1,000,000 may go directly to the Tax Court, and a County Board judgment can be appealed to the Tax Court within 45 days. The Board tests the assessment against the common level range: the average ratio plus or minus 15%. Using the 35.97% ratio implied by the state's two rates, that range runs from about 30.57% to 41.37% of market value; the Director's official average ratio for Milltown, which the County Board applies, can differ slightly.
