Executive Summary

In 2019, the Williamson County (“Wilco”) Central Appraisal District began to explore integrating Artificial Intelligence (AI) into its semi-annual home data collection process to reduce error rates, increase efficiency, and save taxpayer dollars. Specifically, the county focused on improving its process of assigning “Quality Class” to homes by its tax assessors.

They found that FoxyAI’s Quality Score model greatly improved the accuracy and efficiency of their process and saved Wilco a significant amount of time and money as a result.

The Challenge

As in many states, property taxes in Texas provide the largest source of money for local governments to use in order to pay for schools, streets, roads, police, fire protection, and many other state-funded services.

Reviewing, grading, and recording an entire region’s property to reassess taxes is a monumental task in itself. It is further complicated by the fact that the Central Appraisal District has a finite time to complete the task, and each county sets its own custom “Quality Class” scale for grading its property. As such, the District has limited time to train, oversee, validate, and record-keep the work of countless, busy assessors and appraisers.

In automating its “Quality Class” process, the Wilco Central Appraisal District faced the challenge of finding a technology partner that they trusted with this hyper-critical task. This partner needed true Real Estate knowledge, had to be able to work within its custom “Quality Class” scale, and needed advanced AI technology that could perform its quality scoring at a superhuman level.

The Solution

Wilco sourced a referral from its trusted technology partner Tyler Technologies, and subsequently decided to engage with FoxyAI to help automate its “Quality Class” process based on the following attributes:

Wilco’s Central Appraisal office used the “FoxyAI Quality Score’’ model to verify the accuracy of quality classes in over 160,000 photos. They found that FoxyAI’s Quality Score model is currently more accurate in determining Wilco’s “Quality Class’’ than the average assessor, and has reduced error rates by over 60%.

FoxyAI’s Computer Vision technology also saved the Wilco office hundreds of thousands of hours of manual verification time—and, as a result, saved the county more than $900,000 in wage expenses.

Today, Wilco residents continue to benefit from the foresight and action of their local Central Appraisal District.
