Working as an Agent in Flower Mound, TX: Two Counties, Five School Districts
Short answer. Flower Mound lies in Denton and Tarrant counties, and five school districts serve parts of the town. Lewisville ISD covers most of it. With that many overlaps, the county and the district come from the address, never from the town name.

Home sales snapshot, July 2026
These are closed sales of single-family homes in the month, from the multiple listing service, with the same month a year earlier for comparison.
| Flower Mound | |
|---|---|
| Closed sales | 102 |
| Closed sales, year earlier | 100 |
| Median price | $654,500 |
| Median price, year earlier | $630,250 |
| Average days on market | 37 |
| Sold price as share of list price | 96.7% |
| Active listings | 293 |
| Months of inventory | 3.8 |
- Median price was $654,500, up 4% from a year earlier. Homes sold for 96.7% of list price on average after 37 days on market, and 293 homes were listed, about 3.8 months of supply. As a rough rule of thumb, that is a pace that tends to favor sellers.

Small cities have few sales, so figures can swing a lot from month to month. Sales by builders and sales not listed in the NTREIS MLS are not counted. Treat this as background, not a price for any particular home, and check current figures before you quote them.
A town that grew with the airport
Flower Mound had 1,685 residents in 1970 and 15,527 in 1990. The count reached 50,702 in 2000, 64,669 in 2010 and 75,956 in 2020. Wikipedia ties the early surge to the 1974 opening of DFW Airport.
The 2010s growth was 17%. The town has filled in. Most of your work is resale and move-up buyers rather than new lots.
Two counties
The town lies in Denton and Tarrant counties. Check the county on each address. It sets the appraisal district and the taxing units.
Five school districts
Lewisville ISD serves most of Flower Mound. Northwest ISD, Argyle ISD, Denton ISD and Grapevine-Colleyville ISD serve other parts.
Families decide by school. A wrong answer at the start of a search costs trust. Check the district for the exact address before you say anything about schools.
A lake on the southern edge
Grapevine Lake and Marshall Creek form much of the town's southern boundary. For homes near the water, check flood zone status on FEMA's flood map, and ask whether flood insurance applies.
