Finding comparable sales ("comps") is a critical step in supporting your Clayton County, Georgia property tax appeal. By showing that similar homes sold for less than your assessed value, you create a compelling case for a tax reduction. Here's how to find and use comps effectively:
The Georgia Department of Revenue and local boards of equalization look for the following characteristics in comparable sales:
Location: Choose properties in close proximity—ideally within the same neighborhood, subdivision, or street. Different areas of Clayton County can have wide variations in value.
Property Type: Match your property with others of the same type (e.g., single-family homes should be compared to single-family homes).
Size and Features: Comps should be within ±10–15% of your property’s:
Heated square footage
Number of bedrooms and bathrooms
Lot size
Features like garages, finished basements, decks, or pools
Condition: Sales of properties in a similar condition carry more weight. Renovated or distressed sales should be adjusted or avoided if they are not comparable.
Sale Date: Focus on sales that occurred within 6–12 months prior to January 1st of the tax year you're appealing. Georgia law values property as of January 1st each year.
Arms-Length Transactions: Use only legitimate, open-market sales—not foreclosures, short sales, or family transfers.
To gather sales data, use the following sources:
The Property Records Search and Comparable Sales Search Tool allow you to find official sales data for properties across the county.
Use Zillow, Redfin, Realtor.com, or Trulia to find recent sales in your area. Be sure to:
Filter for similar size and property features
Use the map view to stay within your neighborhood
Double-check these sales with county records for accuracy
Agents have access to MLS (Multiple Listing Service), which is more accurate and current than public websites. Many are willing to assist homeowners with comps for tax appeals—especially if you're a past or future client.
Hiring a property tax consultant or a state-certified appraiser can be helpful, especially if your property is unusual or complex. They often have proprietary tools and deep market knowledge.
Here’s how to present your comps in a persuasive way:
Create a Clear List: Include:
Property addresses
Sale prices and dates
Lot and home sizes
Features like garages, finished basements, or decks
Highlight Similarities: Note why each comp is a good match to your home.
Adjust for Differences: If a comp has a larger lot or a recently renovated kitchen, make a reasonable downward adjustment to its sale price—or explain why yours should be valued lower.
Provide Documentation: Include:
Printouts or screenshots from the tax assessor’s website
MLS sheets (if available)
Zillow or Redfin sales records
Stay Within a Value Range: Your comps should support a reasonable estimate of your home’s market value, ideally below the county’s assessed value.
Reference January 1st: Clayton County’s assessment is based on your home’s value as of January 1st of the tax year. Use sales that occurred before or close to this date.
Neighborhood-Specific Trends Matter: Subtle value shifts happen even across short distances in Clayton County. Always keep your comps within your specific subdivision or HOA if possible.
Know Your Deadline: You have 45 days from the mailing date of your Annual Notice of Assessment to file your appeal. This notice typically arrives in late May or early June.
Appeal Levels Differ: Your appeal may go through multiple levels—Board of Assessors, Board of Equalization, or possibly hearing officers or Superior Court. At each stage, the strength and clarity of your comps matter.
