Glendora and San Dimas sit close enough to be compared casually and different enough to punish casual comparison. In the public June 2026 snapshots used for this build, Glendora carried the higher median and positive annual movement; San Dimas carried a lower median and negative annual movement. Both showed relatively short median marketing periods.

The percentage may be a mix signal
Glendora’s positive movement does not mean every Glendora property appreciated 6.7%. San Dimas’s negative movement does not mean every San Dimas owner lost 4.3%. Each median depends on which homes sold in the period. A cluster of high-end or larger-lot closings can move a city median even when an individual segment is flat.
Micro-market differences that should enter the analysis
Glendora historic and north-side homes may require condition, architecture and canyon/foothill adjustments. San Dimas Via Verde and hillside properties may require view, slope, lot-usability and insurance analysis. Conventional subdivisions and condos form different competitive sets in both cities.
What a seller should not do
- A Glendora seller should not add the city’s annual percentage to an unsupported price.
- A San Dimas seller should not assume a negative city median requires discounting a well-positioned micro-market property.
- Neither seller should use the other city as a primary comp without buyer-pool evidence.
- Both should model net, timing and condition—not price alone.
What a buyer can use
A buyer comparing the two should define the property need first: lot, condition, view, access, recurring costs, renovation tolerance and commute. The lower city median may not create the lower all-in cost. The stronger annual price movement may not make a specific property safer or more valuable.
The correct comparison is property against property
Use the city board to choose questions, not to choose the answer. Patrick’s role is to narrow the competitive set and show which differences are supported by market evidence.
