The local read
Buying in Keller means buying resale, and resale here means the corridor's deepest stock of mature-tree, larger-lot neighborhoods. The inspection conversation replaces the design-center conversation: roof, HVAC, and foundation history are your line items, and homes with documented service records earn their asking prices. Because new-construction competition is distant, Keller sellers negotiate on classic terms — which means your leverage comes from preparation and comparables, not from a model home down the street.
What the 2026 appraisal roll says about Keller
Tarrant Appraisal District's adjusted certified totals for the City of Keller (generated July 24, 2026) count 12,210 residence homesteads. Their average market value is $596,943 and the median is $539,540; after exemptions, the average taxable value is $458,958 and the median taxable value is $422,400. The roll's average homestead exemption is $130,268, so expect the taxable figure on a listing's tax history to sit well below its appraised market value — and expect it to reset under your own exemptions after you buy.
The same report puts total new market value added inside city limits this year at about $58.1 million. Haslet, a city with a small fraction of Keller's homesteads, added about $148.6 million. That single comparison is the quantitative version of the point above: Keller's housing stock is largely finished, so your shopping list is mostly resale.
The rate stack on a Keller ISD address
Per TAD's 2026 rate sheet, a Keller city address in Keller ISD stacks Keller ISD at $1.0852, the City of Keller at $0.300417, Tarrant County at $0.186, the hospital district at $0.159, and Tarrant County College at $0.12 per $100 — about $1.85 combined before any special district. Keller offers a 20% local-option homestead exemption plus $40,000 for owners 65 and older; the school district applies the state $140,000 homestead exemption. Because exemptions differ by taxing unit, apply each rate to that unit's own taxable value rather than one blended number. Confirm the school district on the parcel record; city limits and district lines are not the same map.
