Westlake Realtor, facts first.

Westlake sits on the Tarrant and Denton county line just north of Southlake, with a resident population of a little over 2,000 and, according to the Town, a daytime population above 18,000. The Town lists a Fidelity Investments campus of more than 5,000 workers on 300 acres, a Charles Schwab headquarters planned for more than 6,000 workers at completion, and Deloitte University. Zillow's typical home value was about $3.23 million in September 2026, up 2.1% over the year, and HAR showed homes for sale averaging about $5.0 million at roughly $851 per square foot in October 2026.

For tax year 2025, the Town rate is $0.185 per $100. In Tarrant County, a Carroll ISD address pays about 1.58% combined and a Keller or Northwest ISD address about 1.73%; the Denton County side runs about 1.46%. On a $3 million Keller ISD home that is about $52,000 a year, roughly $4,330 a month, before exemptions; Westlake offers a 20% Town homestead exemption plus the state's $140,000 school exemption.

Pull the appraisal district record for any address to confirm county and ISD, since the combined rate ranges from about 1.46% to 1.73%. If Westlake Academy is part of the plan, read its residency policy before you buy, because enrollment depends on living inside the primary boundary. Budget taxes on your purchase price, because the 10% homestead cap is removed when a home sells.

The lesson for Westlake buyers is that two homes on the same road can carry different tax bills and different school options. The Town is served by Carroll, Keller and Northwest ISDs plus Westlake Academy, a Town-owned IB charter open to every resident, and the combined tax rate runs from about 1.46% to 1.73% depending on county and ISD. On a $3 million home, that spread is worth roughly $8,000 a year, so confirm the county and ISD on the appraisal district record before you compare listings.

In Westlake, buyers compare your home to a short list of peers in the same neighborhood, so price against closed sales inside your subdivision and lot size band, not the town average. Highlight what an out-of-state executive cannot see from a listing: the ISD and Westlake Academy eligibility, the county and the actual tax bill. On estate lots, a current survey, drainage and septic or utility records, and documented roof and HVAC service remove the questions that slow luxury deals.
