Harris County is the largest and wealthiest county in Texas. Featuring Houston and its many suburbs, Harris County continues to grow its population and economy. Far more than just the oil and gas industry or the Rodeo, Houston’s economy continues to diversify, drawing more people every year. This has made homes and businesses more in demand than ever before, which has led to the Harris Central Appraisal District (HCAD) handing out record appraisals. In response, the people of Houston have deployed property tax protests at a record rate, with over 516,000 appeals filed in 2024 alone.

Consistently across Texas, the majority of home value has been built in the construction boom between 2001 and 2020.

Homes built from 1981 to 2000 accounted for 22%, or $91.75 billion, which was reached by adding 3.4%.

47% of Harris County Homes Were Overvalued



HCAD County Houses Valued above/below Market Value

Houses Overvalued – 47%
Houses Valued at or Below – 53%

In 2025, it was estimated that only 28% of homes in the Houston area were overvalued. That was easily dwarfed in 2026, which saw 47% of residences be appraised above their market value. HCAD has previously shown restraint, but it works slowly and cannot always keep up with market trends. This is why both overassessment and unequal appraisal are vital grounds for property tax protests.

Evidence of Overappraisal

Houston Metro Single Family Value Appreciation versus HCAD Assessment Increase %

According to a study by local realtors, homes in the Houston metro area appreciated by around 3.7%, which was calculated by studying home prices from January 2025 to March 2026. In comparison, HCAD increased home values by 4.5%. While not a staggering difference, it does show the distance between actual market values and what HCAD measures. If a homeowner suspects that their appraisal is too high, then they would be justified in using a property tax appeal.

Commercial Property Value Trends

According to the Federal Reserve of St. Louis, over the past five years, the value of commercial properties has fallen 7%. This generally signals a persistent weakness in the commercial real estate market, generally because of sinking demand for retail spaces and offices. HCAD appraised commercial property in the county as having grown by 6.7%. While the Houston area is certainly thriving, that is still a big gap.
