Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Jul 2026 - Sep 2026).

Over the latest rolling three-month view ending in September 2026, Black Diamond’s home values have eased compared with a year ago. The typical home value is down about 8 percent year over year, while the median list price has fallen nearly 20 percent, signaling that sellers are pricing more cautiously than in prior years.

Inventory conditions look very different from last year as well. Active listings are up about 63 percent year over year and new listings have surged more than 130 percent, pushing months of supply to around eight months compared with roughly four months a year ago.

Even with more homes on the market, buyers are still moving when they see the right fit. Homes now take a median of about 32 days to go under contract, longer than the peak of the past cycle but quicker than last year, and only about 13 percent of sales close above list as the average sale-to-list ratio hovers just under 100 percent. In this shifting environment, Agent Pronto can connect buyers seeking opportunity and sellers navigating pricing decisions with an experienced Black Diamond real estate agent who understands these trends.

“Choosing Sell With Wes was hands-down, the best decision we made in our home-selling process. From the first meeting to the final phone call once our home sold, our experience was beyond excellent. We had a difficult situation on our hands and needed someone with vision, expertise, and most importantly, patience. Wes and his team fit our needs perfectly. The team's ability to troubleshoot and problem-solve where there were multiple variables was a real strength of theirs. They made us feel like we were their only clients at times, were hands-on, and found solutions where it sometimes seemed there wasn't one. The team is well-balanced, each member bringing their own expertise. We needed all they had, and they did not disappoint! We are so pleased with the outcome. They really knocked it out of the park. I looked forward to calling them again when we are ready to buy. Thank you, Sell With Wes!”

“Ashley was great to work with. We went through a journey of selling a home in, in hindsight, was a crazy and hectic market to navigate, and some very difficult buyers. She was calm, clear, understanding and engaged throughout the process end to end. Thank you Ashley!”

“Mike provided expert advice for a year leading up to the listing. His understanding of my situation and goals/objectives informed our entire engagement. His advice re: repairs, maintenance, and staging got us off to a good start. He did a great job of market analysis and pricing, leveraging his excellent and very well informed sense of the local market. Weekly check-ins kept me informed of our listing and market statistics and informed timely marketing adjustments. This enabled me to weigh my options and make decisions with confidence. All of his recommendations turned out to be spot on, and we sold the home per our objectives. He and Sierra were also a pleasure to work with. Good, informed, diligent people working on my behalf. What more can I ask for? Highly recommended.”

“Donny was incredibly knowledgeable and quick with communication, no matter how many questions I had. He was on top of things through the loan processing issues that cropped up, and was good-humored - which was helpful with my stress! To be very transparent here, Donny is my ex-husband and I still chose to work with him. I'd ask him for help with the next opportunity as well, so I hope that this goes to show how great he is at what he does!”

“Aaron has assisted us in not just one, but two homes and the experience was nothing short of exceptional. He is very knowledgeable, punctual, and experienced in what he does. He was able to get our under contract in only 17 days. We were in the loop throughout the entire process and he always made time to answer any questions we had. I highly recommend his services if you are buying or selling a home! Best real estate in the Yelm area!”

“Excellent team, extremely professional, willing to go the extra mile for their listings. Our sale included moving out of Washington, and Josh and his team were willing to work very closely with us on the entire process. Their tools made it easy to keep up with showings and buyer interest, and the team constantly kept in communication throughout the entire process from listing to closing. We would definitely recommend them over and over again.”

“Dyyana was great! She represented us as our buyer’s agent and was very knowledgeable about the Bellevue and surrounding areas. She is also very knowledgeable about investment properties and strategies to maximize value/ROI for investment properties. She was very accommodating and was willing to show us multiple homes in order to find our home. Her negotiation skills were excellent. She was very responsive and attentive to our needs. Very easy to talk with. Would highly recommend! Thank you, Dyyana!”

“Doug was great as our buyer's agent! We are stationed overseas and bought a house in preparation of returning back to WA. We were worried about the time difference- but Doug was responsive 24/7- up at 1/2am WA time and attentive to our needs. He sent us numerous updates on homes that were available, and was always attentive to our needs. The closing despite being overseas was seamless and easy. We continue to rely on Doug and his contacts long after the sale - and recommend him without any reservations.”

“We had a wonderful experience working with Kristy! From the very beginning, she was incredibly patient, attentive, and supportive throughout our home-buying journey. We had a long list of requirements for our future home, and she always listened carefully, respected our wishes, and never pressured us into making a decision. What we appreciated most was her honesty and attention to detail. She often noticed potential issues with properties that we would have completely overlooked and made sure we were aware of them. We always felt that she genuinely cared about helping us find the right home, not just making a sale. She was also incredibly supportive throughout the mortgage approval process, helping us stay positive during what could have been a stressful time. Thanks to her dedication, professionalism, and kindness, we finally found our home, and we couldn't be happier! We are truly grateful for everything she did for us and would wholeheartedly recommend her to anyone looking to buy a home!”

His attention to detail, honesty, and dedication made the entire experience smooth and stress-free. We truly appreciated their patience, excellent communication, and willingness to go above and beyond to help us. I highly recommend to anyone looking to buy or sell a home!”

“Rebecca and Mike went above and beyond for me throughout the entire process of selling my home. From the very beginning, Rebecca listened to my goals, my timeline, and all of my concerns. She was always checking in, making sure I was okay, informed, and never felt like I was going through this alone. Selling a home while navigating major life changes as a single mom was scary, stressful, and emotional at times. I honestly don’t think I could have made it through this process as smoothly as I did without Rebecca and Mike by my side. They were patient, supportive, knowledgeable, and truly cared about me—not just the sale of my home. They are genuinely good people, and I feel incredibly lucky to have had them in my corner. Everyone needs a Mike and Rebecca written into their story somehow. I will forever be grateful that they were part of mine. If you’re looking for real estate agents who will truly go above and beyond and treat you like a person rather than just a client, I cannot recommend Rebecca and Mike enough!”

“We had such a great experience working with Liliana! She did an amazing job helping us find the right home for us. From the very beginning she was always communicative and flexible with our schedule. She made the whole home-buying process feel much less stressful and was there to answer our questions, explain things, and guide us every step of the way. We truly appreciate all the time and dedication she put into helping us find our home. We couldn’t have done it without her.”

“Our experience in working with Aaron Morrow was exceptional. We first met Aaron at an open house he was hosting, just a couple of doors down from the house we were renting. We sensed a good rapport with Aaron, so we pursued using his services as our real estate agent. We weren't 100% certain what we were looking for ... single-family house, condo, townhouse, city, suburb, old, or new. However, Aaron was always very accommodating and responsive to our evolving criteria. We were very slow to act at times, and Aaron was always patient. We submitted offers on a couple of occasions (and were subsequently outbid), and Aaron always offered the best strategies, knowing our limits. On one date, while looking at a cool, original, mid-century bi-level house in south Seattle, Aaron was so patient as we decided in that moment that we had been looking at houses too large for our needs and that we needed to re-set our criteria one last time. He never got flustered or impatient with us, but rather adjusted to our new outlook. In the end, we found a small house just inside the city limits of far-southwest Seattle, close to transit options, large backyard, and direct paths to Alaska Junction, White Center, and even downtown Burien. This came after looking at properties across West Seattle, Burien, Tukwila, SeaTac, and Des Moines. Aaron was always available to visit properties with us, and he was always on the lookout for properties he found that matched our needs. I fully recommend Aaron as a real estate agent and as a REALTOR. His expertise, skills, and follow-through were exactly what we needed toward finding our new home.”

“TC Wu was a fantastic agent to work with to sell our house in Seattle. Both he and the rest of the team at WPI realty really went above and beyond to do everything we needed to sell our house. TC is professional, responsive, and thorough - all the right characteristics you need in an agent in what is becoming a softer market for sellers in Seattle. From start to finish, TC took extra time to make sure that we did everything we could. He even put up laminated cards informing potential buyers about special features of the house, and took extra time to talk with interested buyers. We were very happy to have sold our house with TC, and would recommend him again in a heart beat to anyone who is looking to sell or buy in the Seattle area.”

“Working with Kendra on the sale of my condo was an outstanding experience from beginning to end. Having worked with numerous real estate agents, I can say without reservation that Kendra operates on an entirely different level. She brought tremendous market knowledge, excellent judgment and a clear strategy to every stage of the sale. She was consistently accessible, kept me informed and handled every detail with professionalism and precision. Whenever a question or concern arose, Kendra was already prepared with an answer or solution. Beyond being an exceptional broker, Kendra is also a genuinely wonderful person. She made the experience feel personal, cared about my goals and represented my interests as though they were her own. The transaction closed successfully, and I could not be happier with the service and guidance she provided. Kendra is the kind of real estate professional everyone hopes to find. I am so glad we met and would enthusiastically recommend her to anyone seeking the very best representation.”

“Carly is the best in the game! Hands down! She knows what she's talking about. I needed help with everything, not knowing what to do or where to start and Carly made it happen. She sold my Mothers home, who's going through early signs of dementia and made the process 95 percent less stressful than it started. I feel beyond blessed. Thank you Carly!!”
