Pull up five real estate sites and search "Richardson TX home price" this week. You will get five different answers, and none of them are wrong.
One tracker puts the city's average home value at $434,035, down 4.2 percent over the past year. Another says the median list price this September sits at $450,000, also down about 5 percent from a year ago. A third, pulling from the trailing twelve months of closed transactions, lands at $502,853. A fourth, looking only at the most recent 30-day window of sales, reports $526,500 and calls that a 17.5 percent jump year over year.
Four sources. Four windows into the same city. A spread of nearly $100,000.
If you're comparing Richardson to Plano or Garland right now, that spread is the actual problem you need to solve before you look at a single house. The gap isn't a data error. It's what happens when a city built from a dozen distinct neighborhoods gets flattened into one headline number.
Start with 75080, the zip code that covers Canyon Creek, much of the city's west side, and the area closest to CityLine. In September 2026, one portal's average home price for 75080 came in at $607,257, with a price per square foot of $266.
Back in April, a different aggregator looked at actual closed sales in that same zip code and found a median sold price of $416,000, down 3.3 percent from the year before, with homes moving in a median of just 17 days.
That's a gap of nearly $200,000 inside one zip code, in the same calendar year. It's not that one number is fake. It's that one is measuring average asking prices across everything currently listed, including a handful of new-construction and remodeled homes near the top of the market, while the other is measuring the median of what actually closed a few months earlier. Average gets pulled upward by outliers. Median doesn't. Asking price and closing price are different conversations entirely.
Here's the mechanism underneath all of it, and it's worth understanding before you trust any single figure:
None of these methodologies is dishonest. They're just answering different questions, and most portals don't tell you which question they're answering.
If you want to see the mix-shift problem at neighborhood scale instead of city scale, look at Canyon Creek, the tree-lined, golf-course-adjacent pocket of northwest Richardson known for mature oaks and mid-century homes updated for modern living.
One tracker's monthly snapshot in May 2026 put Canyon Creek's median sale price at $574,807, down 7.6 percent year over year. A separate site's trailing twelve-month average for the same neighborhood came in at $739,956, up 13 percent.
Same streets. Same school-age housing stock. A $165,000 gap between two credible reports, because one is a single month's median and the other is a rolling year of averages that includes a run of larger, updated homes selling near the top of the neighborhood's range.
This is the pattern to watch for anywhere in DFW, not just here. A single monthly number tells you almost nothing about where a neighborhood is heading. A trailing average tells you almost nothing about what's happening right now. You need both, dated, before you draw a conclusion.
Once you stop asking "what's Richardson's median price" and start asking "what does this specific pocket cost," the picture gets a lot more useful:
That's not a rounding error. That's a $700,000 spread between the least and most expensive named pockets inside one city, and the citywide median tells you about none of them specifically.
If you're cross-shopping Richardson against Plano, McKinney, or Fort Worth, the citywide median is close to useless for that comparison. Two suburbs with identical medians can have completely different neighborhood distributions underneath, and the only way to know if Richardson fits your budget and your priorities is to compare at the zip code or neighborhood level, not the city level.
The days-on-market numbers make this even clearer. Citywide, homes have recently spent anywhere from 34 to 48 days on the market depending on the source. But 75080 alone showed a median of just 17 days in one recent window, and Canyon Creek homes have sold in around 36 days against a national average of 44. Some pockets of this city are moving fast. Others are sitting. A citywide average smooths that gap away right when it matters most to a buyer deciding how aggressively to move.
Which price should I actually trust when I'm comparing Richardson to another city? None of them alone. Ask what window the number covers, whether it's median or average, and whether it's measuring asking prices or closed sales. Then ask for the same figure at the neighborhood or zip code level, since that's the number that will actually apply to the house you're touring.
Is Richardson a buyer's market or a seller's market right now? It depends where in the city you're standing. Zip code 75080 was closing homes in a median of 17 days in a recent window, which reads as seller-favorable. Other pockets of the city have shown longer days on market and more price cuts, which reads as more room for buyers to negotiate. The honest answer is that Richardson is currently running as several different micro-markets under one name, not one market with one temperature.
