Many property-tax disputes begin with market value, but factual data is often easier to verify. If the model starts with the wrong facts, the resulting value may also be wrong.
Where do you get the property record card?
Many assessor websites provide parcel records online. If not, request the record directly from the assessor. Ask for the detailed property card, not only the public tax-bill summary.
Check building measurements
Review gross living area, story count, basement area, finished basement area, additions, porches, decks, garages, and accessory structures. Understand whether the assessor’s measurement standard differs from a real estate listing before assuming a discrepancy is an error.
Check quality and condition
Assessment systems may assign condition or quality grades. If your property requires substantial repair but the record assumes average or renovated condition, document the difference with photos and estimates.
Check improvements
Verify that listed improvements actually exist and are described accurately. A removed structure, unfinished project, or incorrectly coded feature can matter.
Check land characteristics
Lot size, frontage, shape, access, topography, wetlands, easements, and location influences may affect land value. Compare the assessor’s data with surveys or other reliable records.
How do you present a correction?
Create a short list with three columns: assessor record, correct fact, supporting proof. That format makes factual corrections easy to review.
