Lowering your Dimmit appraisal: how it works

  1. 1

    Read your Notice of Appraised Value

    Dimmit Appraisal District mails notices in spring. Compare the market value to what similar homes nearby actually sold for around January 1.

  2. 2

    File by May 15 (or 30 days after your notice)

    File online through Dimmit Appraisal District's portal or on Comptroller Form 50-132. Check both "value is over market value" and "value is unequal compared with other properties."

  3. 3

    Try the informal review

    An appraiser reviews your evidence and often makes an offer before any hearing. Most residential protests settle here.

  4. 4

    Go to your ARB hearing

    If you don't settle, a three-member Appraisal Review Board panel hears both sides. Bring comparable sales, repair estimates and photos.

  5. 5

    Appeal further if needed

    Within 60 days of the ARB's order you can request binding arbitration or file in district court.
