Property valuation notices are landing in mailboxes across Harris County, and many homeowners are in shock. With the home valuations in Harris County fluctuating, according to preliminary HCAD data, thousands of properties may be overvalued for tax purposes.
But how do you know if your property is one of them? This guide outlines the five clearest indicators that your Harris County property valuation deserves a closer look—and potentially a protest.
What Constitutes an "Overvalued" Property?
Before diving into the signs, it's important to understand what "overvalued" means in the context of property taxes. In Texas, your property can be considered overvalued in two ways:
- Market Value: Your appraised value exceeds what your property would likely sell for on the open market as of January 1st.
- Equity: Your property is valued disproportionately higher than similar properties in your area (known as "equal and uniform" taxation).
Both approaches are valid grounds for protest under Texas law, and recognizing the signs of either can save you thousands in property taxes.
Sign #1: Your Valuation Increased Dramatically Despite No Improvements
One of the most obvious red flags is a significant jump in your property's appraised value without corresponding improvements to your home.
What to Look For:
- Increases over 10% when you haven't renovated, expanded, or significantly improved your property
- Jumps that far exceed the average increase in your neighborhood
- Consecutive years of double-digit percentage increases
Sign #2: Your Home Has Condition Issues Not Reflected in the Valuation
The Harris Central Appraisal District typically assesses properties based on exterior observations and statistical models. They don't see what's happening inside your home or underlying issues that affect value.
What to Look For:
- Foundation problems (common in many Houston neighborhoods)
- Roof damage or aging roof (especially important after recent storms)
- Faulty/non-functioning systems (HVAC, electrical, plumbing)
- Unrepaired water damage (particularly relevant in post-Harvey Houston)
- Significant deferred maintenance items
Sign #3: Comparable Properties in Your Neighborhood Are Valued Lower
Texas tax law provides for "equal and uniform" taxation, meaning similar properties should be valued similarly. If your property is valued significantly higher than comparable homes, you have strong grounds for protest.
What to Look For:
- Similar homes (in size, age, and features) with lower valuations
- Properties on your street with substantially different per-square-foot valuations
- Homes that have sold recently for less than your appraised value
Sign #4: Recent Sales Data Doesn't Support Your Valuation
The ultimate test of market value is what buyers are actually paying for similar properties. If recent sales don't support your property's valuation, you have a strong case.
What to Look For:
- Recent sales prices of similar homes in your area
- Current listings that have been on the market for extended periods at prices below your valuation
- Downward price trends in your specific neighborhood
Sign #5: There Are Factual Errors in Your Property Record
HCAD maintains records on over 1.8 million properties. With that volume, errors in property descriptions are surprisingly common—and they can significantly impact your valuation.
What to Look For:
- Incorrect square footage
- Wrong number of bedrooms or bathrooms
- Inaccurate lot size
- Features you don't have (like a pool, garage apartment, or an outdoor kitchen)
- Incorrect property classification

If you recognize any of these signs, your property may indeed be overvalued for tax purposes. Here's how to find out for sure:
- Review your property details on the HCAD website for factual accuracy
- Research comparable properties in your neighborhood using HCAD's property search
