Homeowners Save Double with O’Connor

According to WCAD, it is believed that 50% of homes in Williamson County were over assessed in 2025. This comes on the heels of a giant spike in value that saw home values surge by 6.3%, resulting in a total of $104.64 billion. This was on top of a 4.1% increase from 2024. While thousands of appeals were deployed, they only managed to claw back 0.6%. Most value was concentrated in homes worth between $250,000 and $500,000, which totaled $48.43 billion. This was followed by those assessed at $500,000 to $750,000 with $30.48 billion. These achieved cuts of only 0.4% and 0.6% respectively. Even the largest homes only saw a reduction of 1.4%. Homeowners that joined O’Connor got much stronger results, including a 1.3% decrease to the total. Residences worth between $250,000 and $500,000 were reduced by 1.1%.

Much like other newly suburbanized counties, such as Denton, while Williamson’s values broke the bank, it was not because of being filled with giant mansions. Huge luxury homes only contributed $176.43 million to the total. The two largest blocks with modest homes. Those between 2,000 and 3,999 square feet were responsible for $64.45 billion in value. Residences under 2,000 square feet added $32.23 billion to the total. These saw cuts of 0.6% and 0.5% respectively. Homes measured between 4,000 and 5,999 square feet added $6.74 billion after a reduction of 0.9%.

Like other up-and-coming counties, the majority of Williamson County’s residential value was built recently. 51.3%or $53.41 billion in total, was constructed between 2001 and 2020 alone, even after a reduction of .05%. About 24.1% was built from 1981 to 2000, while 16.6% came from new construction. These two timeframes saw moderate cuts of 0.5% and 0.8% respectively. New construction was the fastest-growing category, obviously, and is already responsible for $17.30 billion of the total. Land and older homes only combined for 7.9% of all residential value. This clearly illustrates a young and vibrant community.

Business Owners Saved Nearly $21 Million in Taxable Value with O’Connor

Thanks to WCAD, commercial property values in the county received an overall increase of 10% to the total. After diligent appeals resulted in a cut of 4%, the total was calculated at $36.82 billion. Like all of Texas, most commercial value was generated by properties over $1.5 million. In this case, the total was $27.74 billion. These large properties managed to land an excellent cut of 4.7% thanks to appeals. Properties assessed between $1 million and $1.5 million experienced a decrease of 1.8%, resulting in a total of $6.94 billion. We at O’Connor were able to land our business clients a bigger return, with an overall slicing of taxable worth by 5.9%. When put together, we managed to save our clients $20.91 million in value.

Like most urban, suburban, or exurban counties, Williamson’s No. 1 commercial property was apartments. Multifamily housing got a reduction of 5.2% thanks to protests, which resulted in a total of $14.12 billion. Raw land, representing limitless potential, was in the No. 2 spot with $8.18 billion after a small reduction of 1.5%. Offices totaled $5.08 billion after a reduction of 4.3%, while retail reached $4.44 billion after being protested down by 3.8%. Warehouses got a cut of 4.3%, while hotels got a decrease of 4.1%.

When it comes to the age of construction for commercial properties, there is an even greater recency bias. Buildings constructed during the 2001 to 2020 boom period are still No. 1 with $14.27 billion in value. This is followed by new construction, which already equates to 20.9% of all value, totaling $7.69 billion. These two timeframes received cuts of 4.8% and 4.3% respectively. Land was in third place, as stated above, while those constructed between 1981 and 2000 took fourth place with $6.15 billion after a strong reduction of 4.8%. The two oldest categories only combined for 1.7% of the total. This heavy weight toward recent construction and land shows just how much potential is waiting to be tapped in Williamson County.

Office Value Slashed 11%

While they may not be what people picture when they think of a suburban county, offices are increasing in importance across Williamson County. While most of this value is thanks to recent construction, it is not as lopsided as the overall commercial number. 37.3% of office value was constructed between 1981 and 2000, a total of $1.89 billion, and this was after a reduction of 4.3%. The largest chunk still came from those built between 2001 and 2020 with $2.21 billion. New construction is quickly shooting up the charts with a total of $818.30 million. These two recent categories were reduced 3.9% and 5.1% respectively, thanks to diligent property tax appeals. Office owners that signed up with O’Connor managed to nab even bigger savings, including a massive 11% reduction in the overall total. Those built between 1981 and 2000 got a 13.5% reduction, while those from 2001 to 2020 were cut by 7.3%.

WCAD divides all offices into three categories. The main one is high-rises, which totaled $3.14 billion after a reduction of 4.7%. Medical offices followed with a reduction of 3.4%, which resulted in a total of $1.04 billion. Low-rise offices finished just behind medical offices with a total of $893.45 million after a cut of 3.9%. We at O’Connor were able to reduce high-rises by 18.2%, saving owners over $1 million in taxable value.

O’Connor Cuts Warehouse Value by 20.5%

Warehouses were the fastest-growing category in all of Williamson County, adding 24.4% to their value in 2025. While appeals were predictably launched, only a savings of 4.3% was achieved for the overall total. Much of this growth was thanks to new construction, with 48.7% of all value being built after 2021. This means that $1.83 billion was just added to the books after a reduction of 3.4%. About $1.49 billion was constructed from 2001 to 2020, resulting in a total of $1.48 billion after reductions. O’Connor customers were able to slice 20.5% from the combined total of warehouses in 2025, beating the county average by 476%.

WCAD only categorized warehouses into two subtypes. Office warehouses had a grand total of $2.65 billion in value, which was achieved after a reduction of 2.1%. Mini warehouses managed a much larger cut of 9%, which brought their combined value to $1.11 billion.

Appeals Even the Playing Field

While tax rates are out of the hands of both taxpayers and WCAD, appeals allow residents the potential to lower their taxable value, which can then have a great effect on the tax bill. When used in conjunction with the many exemptions available in Texas, protests can produce significant savings for business owners and homeowners. They also act as a counterbalance to massive growth spurts, like what Williamson County has seen in recent years and can help stem the bleeding. Appeals can truly make a difference for taxpayers of all kinds, and they were able to achieve a total reduction of $2.13 billion in taxable value. The best part about appeals is that they can only lower a home’s value and never raise it, which means there is no downside to exploring the protest process.

When clients took their property tax protest to O’Connor for help, we were able to get them even better deals. While smaller than we may have hoped, the 1.3% reduction to the overall home total was still double the rate of the county number, while 5.9% represented a strong cut to commercial property, considering the dollar amount of each individual piece of real estate. When combined, our clients were able to save $42.72 million in value. We at O’Connor also believe in the power of cumulative victories, meaning we will protest your taxes annually, stacking each victory to get a better deal every year. This is done with no cost to you, as all protests when you partner with O’Connor are free to use.
