Dallas County · DCAD appraisal neighborhood
Plantation Dr, Whispering Hills Dr, Magnolia Dr and 19 other streets — Coppell (Dallas Co)
Neighborhood code 5OSN01
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.

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.
