You Can Protest Your Williamson County Tax Assessment


If your Williamson County Appraisal District (WCAD) property tax bill gave you a heart attack, please call us at (512) 541-2107 to schedule an appraisal to help you appeal your Williamson County property taxes.

A real estate appraisal does not determine the value of your home the same way that the tax assessor’s office does. They use huge databases and mass modeling software to determine values and that means that some always come in too high and some always come in too low.

We evaluate properties on an individual basis and can take into account the differences that your property has from other properties that the taxing district might think are similar even if they’re not.

If you think your tax assessment is too high, you can protest the value that the tax assessors office gave to your home and try to get your taxes lowered on your property.

    Understanding the Williamson County Texas Real Estate Sales Data

    Although we prefer to report median values for real estate sales, in this instance it made more sense to report averages.

    When you have such a large number of sales, the average values are a better indicator of where the market is than when you only have a smaller number of sales where a single really high priced (or low-priced) home can skew the data.

    You can see this in the difference between the median price and the average price for this year-over-year comparison.

    A median value is the one where half are higher and half are lower, if you lined them all up from lowest to highest.

    An average is when you add them all up then divide by the number of items.

    Average values are more easily skewed by unusual data points than medians are.
