Tennessee assessors value hundreds of thousands of properties using mass appraisal — statistical models applied across whole neighborhoods. It's efficient, but it can't see what makes your specific property different, so individual homes regularly come out too high.
Warning signs
- Your appraised value is above what comparable nearby homes have recently sold for.
- Your assessment jumped sharply in a reappraisal year, faster than your neighborhood.
- The property record is wrong — too much square footage, a basement marked finished, the wrong condition or year built.
- You recently bought the home for less than its current appraised value.
- Your home has condition problems (deferred maintenance, a busy road, an odd lot) the model ignores.
What to do next
If two or three of these ring true, an appeal is worth a look. Start by checking your property record for errors, then pull a few comparable sales. If the numbers support a lower value, request an informal review with the Assessor.
