Thank you for posting in the Community. We realize this matter is important to you. The estimates provided are based on several different factors. These factors include characteristics of recently sold homes, publicly available data by location and real estate trends. Changes to any of these variables may affect the determination of the estimated market value.
If you notice any discrepancies, you may contact your local tax assessor's office to update their information. Thank you for being a valued USAA member. -Gus
