How To Find Comparables for a Property Tax Appeal Easily

Most people are struggling with paying their property tax bills, so consider yourself lucky if you live in a state with low property taxes. If you are making your payments without second-guessing the sum—think again. Local assessors can make a mistake in calculating your property value, so you may be overpaying without knowing.

One way to challenge your property tax bill is to compare your property value to those of similar homes. DoNotPay will show you how to find comparables for a property tax appeal and file an appeal in a short time!

How Are Your Property Taxes Calculated?

Property taxes are calculated according to your property’s value and the local property tax rate. Local assessors will typically reassess your property every one to five years and set your property tax bill accordingly.

The assessed value of your home serves as an estimate of your property’s market value. To correctly assess a home’s market value, the assessor must pay attention to the following:

  • Owner’s maintenance expenses
  • Possible replacement costs for the home
  • Completed improvements of the property
  • Exact income you are making from the property
  • Possible interest that would be charged for purchasing or constructing a similar home 
  • Comparable properties’ prices on the current market 

The assessor can estimate the property’s market value in one of three ways or by combining all three. You can look at a more detailed explanation of these methods in the table below:

The assessor establishes your property’s value based on how much it would cost to replace it


Your property’s value is assessed by the income you would gain from renting it

Sales evaluation

The assessor determines the property value by using records of comparable sales. The criteria include:

  • Location
  • Improvements
  • Market conditions
  • State of the property

The Comparable Sales Approach to Filing a Property Tax Appeal

If you need help paying your property taxes, you can use a comparable sales approach as the basis for your property tax appeal.

The comparable sales method implies using recent sales prices of comparable homes, or comps, to determine your property’s value. Comps represent houses that are similar to yours in size and price. If the value that your assessor set for your property is higher than the value of the comparable sales, you have grounds for an appeal.

You can prove the mistake in a property assessment in one of three ways:

  1. Hire an appraisement expert to reassess your property’s valueyou can compare the recent appraisal with the property value set by your assessor and use it as evidence in your appeal
  2. Use your property’s purchase price—this only works if you have purchased your property recently. You can compare the purchase price to the value assigned by your assessor. Any major difference counts as a reason for the appeal
  3. Find comps for your property on your own—find homes that are similar in size and price to your property and look for any inconsistencies

How To Get Comps for a Property Tax Appeal

Comps are not difficult to find, as long as you know what to look for. Comparable property sales records are available online to anyone, not just real estate professionals. If you want to reduce the search time, you can apply some of these tricks:

  • Visit your local county auditor
  • Access a local property website to check out other property records in your area
  • Go to websites such as and provide essential information about the property to find comps
  • Talk to a tax evaluation expert—they can assist you in finding a comparable property in your area, help you understand the criteria, and explain how they affect your property value

Make sure that the sales data and assessed value of comparable properties match yours. There shouldn’t be any major differences in property tax bills between the comparable homes.

Before you use the comparable sales approach, you need to check if the comps are still comparable to your home. If any of the neighboring homes had improvements, you don’t belong in the same property tax category. Your local assessor should make a note of that and perform the necessary changes.
