Diamond Bar sits in the hills of eastern Los Angeles County, right at the 57/60 freeway interchange: one of the more heavily used interchanges in the region, and the reason the city works as well as it does for LA and Orange County commuters. It’s an almost entirely master-planned community, built up mostly from the 1960s through the 1990s across genuinely hilly terrain.
That hillside setting means view lots and larger homes are common, and it prices accordingly: one of the higher-priced cities on this list, closer to Chino Hills and Claremont than to its flatter San Gabriel Valley neighbors.
Diamond Bar fits a buyer commuting toward LA or Orange County who wants a quieter, more residential base with real freeway access. For a seller, view and lot placement on the hillside drive price here more than square footage alone.
The market right now
Diamond Bar’s median is up over 10% year over year, the strongest appreciation of any city in this batch, with homes going under contract in about three weeks. For a seller, that’s about as strong a market as this list gets: current pricing should reflect the past year’s real gains. For a buyer, it means being prepared to move quickly and competitively on hillside and view homes in particular.
