Property assessments play a role in how your annual property tax bill is calculated. If your assessment is higher than it should be, you could be paying too much in property taxes. One way to determine if your assessment is too high is to compare your home’s assessed value to those of similar homes around you. The Detroit Assessment Gauge from Regrid can help you do this. In this map, you can see how much the assessed value per square foot varies from the average assessed value per square foot for single family homes in the same census tract. If a home’s assessed value per square foot is higher than the census tract average, it might be overassessed. The darker red a property appears on the map, the farther above the census tract average its assessed value per square foot is. The darker green, the farther below the census tract average assessed value per square foot.
