Dallas County · DCAD appraisal neighborhood

Castle Rock Ln, Brook Glen Dr, Jester Dr and 21 other streets — Garland (Dallas Co)

Neighborhood code 2RSJ21

Every year, DCAD compares recent sales in each neighborhood with its values. If the neighborhood's sales ratio is more than about 5% from 100%, it typically targets the neighborhood for reappraisal, assuming enough sales data. It uses the same model and location factor for homes of the same building class within a neighborhood. That's why your neighbors' values tend to move together, and why knowing your neighborhood matters.

This is the middle home's own year-over-year change. It can differ from the change in the median value, because the median home is not the same home each year.

The 10th to 90th percentile range of values in the 2026 certified roll as of Sept. 15, 2026 is $271,965 to $382,730. This middle 80% describes variation across the neighborhood, not a value for any one property.

Certified below the April notice

Using the certified roll as of Sept. 15, 2026, 10.9% of homes with both an April notice and a certified value had a certified value below their April 2026 notice value. A lower certified value can result from a protest, an informal settlement or an appraisal district correction.

Sources and method

Neighborhood classification: workpaper 005_dallas_neighborhood_types.sql. Last verified 2026-10-08.

This is a 2026 residential-only appraisal-neighborhood assignment. The certified roll source is DCAD2026_CURRENT, dated September 15, 2026; proposed values are the April 2026 notice values. Approximately 5% of residential accounts are absent from the certified file and are unavailable for this analysis. Method: see How we verify. Source release date: 2026-10-05.

The certified-below-notice comparison uses accounts with both notice and certified values. A lower certified value can result from a protest, an informal settlement or an appraisal district correction.

Medians are shown in whole dollars. Year-over-year figures show the typical home's own percentage change, not the change between neighborhood medians. Statistical summaries require at least 30 homes; the below-notice share requires 30 homes with both an April notice and a certified value, and the median reduction requires 10 homes with reduced values.
