Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Jul 2026 - Sep 2026).
Diamond Bar currently leans toward sellers, with the market gauge at 27 indicating sellers still have an edge but with moderating conditions. Inventory has expanded to about 4.7 months of supply in the latest rolling three-month period, up sharply from around 2.9 months a year ago. Homes are also taking longer to sell, with the median days on market rising to 62, compared with roughly 54 days in the same period last year.
Prices are telling a different story than speed and supply. The typical home value over the latest three-month window is up more than 15 percent year over year to about $1.10 million, even as the share of homes selling above list has dropped to about 21 percent from roughly 29 percent a year ago. Fewer bidding wars and a lower average sale-to-list ratio of 97.7 percent suggest buyers have gained some negotiating power compared to recent years.
Sales activity has cooled notably on a yearly basis. Homes sold in the rolling three-month period are down more than 23 percent year over year, while pending sales have fallen about 20 percent, even as active listings have grown slightly. With more choices, slower pace, and higher prices, both buyers and sellers benefit from an Agent Pronto–recommended real estate professional who can help them navigate the Diamond Bar market and protect their interests.

“I felt very comfortable with Sylvia. She was sincere, empathetic to my situation, and guided me through the probate sales process. The bank situation was a bit complex, but she was patient and communicative with me as well as with the buyers. We had a mutual respect and we both followed through on what we set out to do. I am extremely grateful to Sylvia for being trustworthy and walking me through the selling process from across the country. I would highly recommend Sylvia to my friends and family.”

“Our Mom had recently passed and needed to sell her home in Lancaster, CA. I have known Amy for a long time and quite familair with her real estate knowledge and skill. However, being that it was so far away from where she is based, we weren't sure she could help us. Amy assured us (My Brother and Sister-in-law) that the distance would not be an issue. She was right! As soon as we started with Amy, everthing went very smooth, fast and easier than we had anticipated. Amy is very knowledgeable, experienced, professional and always accessible if we had any questions or concerns. I would definitely recommend Amy to friends and family members for any real estate needs.”

Rebecca was always available to answer my questions and never made me feel like I was bothering her. She was patience and firm when necessary. I would definitely use Rebecca Anderson again if necessary.”

“Coming from a marketing backgound. Jack Ma's a methodical and analytical approach resonnated with me from the start. You may get lucky with one sale. But in the long run, a comprehensive plan yields more consistant results. I spoke with 2 other realtors before deciding to list with Jack Ma. The other realtors were nice enough and seemed familiar with my locality, but didn't present a thorough marketing plan. Ultimatly, that's what swayed me and Jack delivered! Highly recommended!”

“A very pleasure working with Monica”
Century 21 Masters
“Thanks to Nicole, I was able to purchase a home that I absolutely love. If you're looking for a realtor who is professional, trustworthy, hardworking, and truly has your best interests at heart, I highly recommend reaching out to Nicole. You'll be glad you did. As a first-time homebuyer, I had a lot of questions. Finding Nicole was one of the best things that could have happened. She was incredibly patient, knowledgeable, and always willing to take the time to explain things in detail. Even when I thought I had done all the research possible, she always had helpful insights and advice that made a big difference. What stood out most was her dedication. No matter when I reached out, she was quick to answer my questions and made me feel supported. It never felt like I was just another client; she truly cared about helping me find the right home. Let her help you find your dream home too. I am even going to work on some future investment endeavors with her.”

“Working with Karen was excellent, she made sure to be there for us in every step of the process, was kind and patient enough to explain things to us and made sure we were comfortable. I do believe she's wonderful in her job and very professional. Although I would recommend her to change some of the contacts for some of the services that comes with buying a house, like the house inspection one and the carpet cleaning services; nothing to do with HER work but something to consider.”
Century 21 Allstars
