Search property records
Live-queries the Texas Open Data Portal‘s public Collin CAD appraisal-roll dataset (Socrata, free, no API key required for this volume of use). Not a scrape — this is the county’s own open data feed.
vffy-snc6, published for the 2025 roll). Collin CAD republishes this under a new resource id each year — if results stop returning, that id below in the code needs updating to the current year’s dataset from collincad.org/open-data-portal. Full text search ($q) is used rather than fixed column filters, since Socrata makes that reliable without needing to hardcode this dataset’s exact column names. For anything beyond light traffic, register a free Socrata app token at data.texas.gov developer settings and add it below — it removes the shared rate limit.
Property tax estimator
Estimate an annual bill from an appraised value and the tax rates of each taxing entity that applies to a parcel (county, city, school district, and any special districts). Default rates below are 2025–26 approximations — replace with the parcel’s actual rates from its Collin CAD record for an exact figure.
Rates vary block by block depending on city and school district (e.g. Frisco ISD vs. McKinney ISD vs. Plano ISD). Swap in the exact rates shown on the parcel’s Collin CAD notice for an accurate estimate.
