Dallas County · DCAD appraisal neighborhood
Mark Twain Dr, Old North Rd, Joanna Dr and 12 other streets — Farmers Branch
Neighborhood code 5ASL09
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.

| 2025 | $316,680 |
| 2026 (certified roll as of Sept. 15, 2026) | $319,470 |

Using the certified roll as of Sept. 15, 2026, the typical home's own value rose 0.8% from 2025 to 2026. Among homes with both an April notice and a certified value, 14.3% ended below their April notice. Among those homes, the median reduction was $14,655.

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.

Using the certified roll as of Sept. 15, 2026, 14.3% 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.

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.
