5 Signs Your Home Is Overassessed

Articles
Nov 28, 2025

According to the National Taxpayers Union Foundation, 60% of U.S. homes are overassessed. This guide reveals the five most common warning signs that you're paying too much in property taxes—and exactly what to do about it.

5 Signs Your Home Is Overassessed

Key Takeaways:

  • 60% of U.S. homes are overassessed according to the National Taxpayers Union Foundation
  • Assessment exceeds market value – compare to recent comparable sales
  • Property record errors – wrong square footage, features, or bedroom count
  • Unequal treatment – your assessment jumped more than similar neighbors
  • Condition issues ignored – aging roof, HVAC, foundation problems
  • Sign #1: Your Assessment Exceeds Market Reality

    Ask yourself: Could I actually sell my home for the assessed value right now?

    If the answer is no, you may be overassessed. Check recent sales of similar homes. If comparable homes sold for $395,000-$410,000 but yours is assessed at $450,000, you have grounds for a protest.

    Sign #2: Errors in Your Property Details

    Common errors to look for:

    • Incorrect square footage (often overstated by 50-200+ sq ft)
    • Wrong bedroom or bathroom count
    • Non-existent features (pool, garage, outbuilding)
    • Incorrect lot size or year built

    Sign #3: Your Assessment Jumped More Than Neighbors

    If your assessment spiked 15% while your neighbor's rose only 3%—even though the homes are similar—you may have an equity argument.

    Sign #4: Condition Issues Not Reflected in Value

    • Roof nearing end of life (15-20+ years old)
    • Outdated or failing HVAC system
    • Foundation problems
    • Original 1980s-90s kitchens/bathrooms

    Sign #5: External Factors Hurting Your Value

    • Backing up to a busy road or highway
    • Adjacent to commercial or industrial property
    • Near high-tension power lines
    • Flight path or railroad noise
    • Flood zone or drainage issues

    What to Do If You're Overassessed

    1. Gather evidence: comps, photos, property records, repair estimates
    2. File your protest before the deadline
    3. Attend your informal hearing and present your case

    85-95% of informal protests in Texas result in some reduction. See our primary home tax protests page.

    FAQs

    Compare your assessed value to recent sales of similar homes within 0.5 miles. If your assessment is 10% or more above what comparable homes actually sold for, you likely have grounds for a protest.
