How to know if your Spotswood home is over-assessed
Every property in Spotswood is assessed in New Jersey's MOD-IV system. Because towns rarely reassess every year, your assessment can drift away from what your home would actually sell for. Middlesex County's 2024 equalization ratio is 46.22%, which means assessments in the county run, on average, at that share of true market value. Dividing your assessed value by the ratio gives an implied market value you can compare against your assessment.
If your assessment looks high relative to market value and to comparable homes nearby, you may have grounds to appeal. NJ appeals are filed with your County Board of Taxation and are due by April 1 each year (January 15 in a municipality that has just completed a revaluation). Use the free lookup above to get a HIGH / MEDIUM / LOW appeal signal for your specific address.
