Working as an Agent in Richardson, TX: Split by County and School District

The Bauer Group team. Published September 29, 2026. Updated October 8, 2026.

Short answer. Richardson is about two-thirds in Dallas County and one-third in Collin County, and the school district follows the county line. Check the county and district by address. The city also has a large university, a corporate base and light rail.

What this suggests

21% of homes were built since 2010, and the median home dates to 1986. These are mostly established neighborhoods with some newer pockets, and 44% of homes predate 1990.
Only 51% of occupied homes are owner-occupied. A large share of homes are rentals, so landlord and tenant basics come up.

This is our reading of the numbers, not a Census statement. Every neighborhood differs.

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.

	Richardson
Closed sales	86
Closed sales, year earlier	99
Median price	$505,000
Median price, year earlier	$460,000
Average days on market	32
Sold price as share of list price	96.2%
Active listings	256
Months of inventory	3.4

Median price was $505,000, up 10% from a year earlier. Homes sold for 96.2% of list price on average after 32 days on market, and 256 homes were listed, about 3.4 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.

Two counties, two school districts

Richardson covers about 27 square miles. Roughly 18.2 square miles are in Dallas County and 9.2 square miles are in Collin County. Richardson ISD serves the Dallas County part, and Plano ISD serves the Collin County part.

The county decides the appraisal district. The school district follows it. A home two blocks from the county line can have a different tax roll and a different school.

The numbers

Richardson had 99,223 residents in 2010 and 119,469 in 2020. That is steady growth in a city that was largely built out before 1990.

A university, a corporate base and light rail

The University of Texas at Dallas has its 445-acre main campus inside Richardson. The city is nicknamed the Telecom Corridor. Wikipedia reports more than 5,000 businesses in the city, including AT&T, Verizon, Cisco, Samsung and Texas Instruments.

DART light rail has four Richardson stations on the Red and Orange lines: Spring Valley, Arapaho Center, Galatyn Park and CityLine/Bush. Transit access is a selling point for some buyers. That is our reading. Ask each client whether it matters to them.
