Common Errors to Look For

  • Wrong square footage: The most common factual error. Even 100-200 extra square feet can inflate your assessment.
  • Extra rooms or features: Assessor shows a finished basement, extra bathroom, or pool that does not exist (or was removed).
  • Wrong property class: Classified as commercial when it is residential, or as non-homestead when you live there.
  • Missing exemptions: Your homestead exemption is not showing up.
  • Wrong year built: An older home recorded as newer may be assessed at a higher value.

Property record errors are surprisingly common. The most frequent mistakes include incorrect square footage, wrong number of bedrooms or bathrooms, a finished basement listed when yours is unfinished, or an extra garage bay that does not exist. Each of these inflates your assessed value and your tax bill.

To check for errors, request your property record card from the assessor's office. Walk through your home with the card in hand and compare every line item. If anything is wrong, document the correction with measurements, photos, or building permits. Presenting a clear error to the review board is often the fastest path to a reduced assessment.

Comparing Your Assessment to the Market

The most important question is whether your assessed value is in line with what similar homes are actually selling for. After checking your record:

  1. Look up recent sales of similar homes within a half mile
  2. Compare their sale prices to your assessed value
  3. If your assessment is more than 5-10% above comparable sales, you may be over-assessed

Our free property tax analyzer does this comparison automatically. Enter your address and get an instant analysis of how your assessment compares to local market data. If your property looks over-assessed, we will show you how much you could save through an appeal.

When selecting comparables, focus on properties that match yours in the ways that matter most: location, size, age, and condition. A comparable sale from your same neighborhood carries more weight than a lower sale price from across town. Aim for homes that sold within the past 6 to 12 months, and document each one with the address, sale price, sale date, square footage, and any significant differences from your property.

If you cannot find enough sales in your immediate area, expand your search radius gradually. Start within half a mile, then one mile. Explain to the review board why each comparable is relevant to your property, especially if it is not on the same street.

Your Next Steps

Do not let this information sit. Take action this week:

  • Review your most recent assessment notice. Pull it out and check every line. Look for errors in square footage, lot size, bedroom count, and property features. Mistakes here are more common than most homeowners realize.
  • Pull comparable sales data. Find 3 to 5 similar properties near you that sold recently. If they sold for less than your assessed value, you have the foundation of a strong appeal.
  • Check your exemption status. Contact your county assessor's office and confirm which exemptions are currently applied to your property. Many homeowners qualify for exemptions they have never filed for.
  • Set a deadline reminder. Find your appeal deadline and put it on your calendar with a 2-week advance warning. Missing the deadline costs you a full year of potential savings.
