  • Geoff listed and sold my home

      Geoff is an amazing man! If you want to sell your house just listen to his advice and do whatever he suggests. My parents needed to move into an assisted living facility. Geoff helped us step by step navigate the whole process of getting the house cleaned and ready to show. He had great contacts to help with handy work as well as cleaning and gardening. Bottom line....The house sold for a great price! Thank you Geoff!

    • Geoff listed and sold my home

        Geoff helped me with a real estate purchase and sale in Upland. He was fantastic and professional. To be honest I was a little reluctant to call him because I thought he only services higher value homes. He didn't care what the value of the home was and he treated it like it was a million dollar deal and was on top of every step in the process. Geoff probably didn't know it at the time but I was preoccupied with my father in and out of the hospital and I didn't have much time to be involved in the transaction. Geoff took care of the whole thing and was a constant professional! I'm so glad I chose him.

      • Geoff listed and sold my home

          The best Realtor in town, he gives you realistic and objective advice whether you are trying to sell and/or purchase a home. He backs up his pricing with real data and comps. If you want someone who is professional, highly knowledgeable of Claremont, communicative, and honest, Geoff is the realtor to choose! Huge difference after dealing with a bad experience with another realtor. He was able to turn our listing around and sell our house within two weeks.

        • Geoff listed and sold my home

            I have worked with Geoff for 25+ years, over the course of a number of real estate transactions. He is professional, knowledgeable, and attentive to the concerns of his clients. His knowledge of the Claremont area is deep and he has facilitated the sale or purchase of homes in every neighborhood so that his recommendations are well-grounded. His advice in the listing, staging, pricing, and processing of my most recent sale was flawless and I am satisfied that I received the best price for my home. Geoff listened carefully, was always well-prepared with appropriate documentation for every meeting we had, and had a number of recommendations for local referrals for the few repairs that were needed prior to the listing. The process could not have been smoother. I know that Geoff is the best in the business, and have referred many friends and colleagues to him over the decades. He will certainly always have my "return" business for the next purchase or sale.

          • Geoff listed and sold my home

              Geoff Hamill assisted me in the past with selling my home, as well as just now, with buying a property in Claremont. Once again, Geoff exceeded all my expectations. He did an amazing job to secure a truly exceptional property for my family. The complete buying process was handled in the utmost professional manner. His knowledge of the Claremont area, paired with an unlimited pool of expertise is unbeatable. With great confidence, I would highly recommend Geoff to anyone in the status of buying or selling a property.

            • Geoff listed and sold my home

                Geoff has been our family Realtor for over 15 years having assisted in the sale of my parents home, buying my mom's own home, and the sale of her home. My last experience with Geoff was during a difficult time when he assisted in selling my mom's house after her passing. He was personable, sensitive during our grieving period, and expressed great concern about the wellbeing of my remaining family members. The house sold quickly and for the asking price we were looking for. Geoff doesn't hesitate to play "hardball" with buyers who might be trying to take advantage of any situations and ensures you get the fair value of the home you're selling. He's professional and an all-around nice guy to do business with.

              • Geoff listed and sold my home

                  Geoff Hamill was my agent for the sale of my family's property in Pomona. He expertly guided me through the whole process and very quickly after the initial listing, we received several competitive offers. It was an unusual property with out-of-the-ordinary circumstances and with Geoff's expertise we achieved a successful sale in a very timely manner. I appreciated his expertise, professionalism, sensitivity and attention to detail. He is a consummate professional and I highly recommend him!

                • Geoff helped me buy a home

                    If you're looking for real estate in Claremont, I highly recommend Geoff Hamill. He's truly engaged with the community, and his knowledge and expertise is unparalleled. From a seller's perspective, it is crucial for a realtor to accurately assess the value of the property when you're ready to sell, as it will ultimately maintain or increase the value of the property. With his experience, Geoff has successfully moved multiple properties in a timely and efficient fashion. Geoff takes the time to sincerely get to know his clients; he understands your needs, budget, and interests, and he genuinely cares about finding a property that is the best fit for you.

                  • Geoff listed and sold my home

                      Geoff is very professional and knowledgeable in this business. We always felt very well taken care of and knew he was always acting in our best interests. He trusted his advice, honesty and guidance through every step of the process and we were able to have successful transactions in selling and buying with Geoff's help. He is truly an asset to have on your side when buying or selling a house

                    • Geoff listed and sold my home

                        I have had the opportunity to work with Geoff on multiple transactions. He is extremely professional and has proven to be an effective negotiator advocating for his client. He has been prompt in all communication and is always clear as to what needs to be done. It has been a pleasure working with him and hope to do so again

                      • I want to thank Geoff for his help with the purchase of Trails End Ranch in Webb Canyon. I really appreciated his staying on top of the extensive due diligence that was required and making sure that all of the details were completed and properly communicated back to the appropriate parties. Geoff's professionalism and attention to every detail made a complicated transaction worry-free for me, which I very much appreciate.

                      • We absolutely loved working with Geoff! First of all, he is very patient and attentive - we're very particular about what we wanted in a house and Geoff listened and delivered! He is *the* expert in Claremont real estate and the surrounding areas. He is a skilled negotiator and someone you want to represent you when it comes to negotiating with the opposing party. He patiently guided us through the negotiation process and we're very happy with the result! It also helps that he's very well-respected in the real estate community - everybody knows Geoff as one of the best realtors in Claremont area. The buying process could get so complex but Geoff made it easy for us to understand the important things and to focus on the priorities. I'd highly recommend Geoff to my closest friends and family.

                        - Michael Steinberger, Pomona College, Claremont
                      • Geoff Hamill and the associates that work with him are spectacular. Geoff is always available for conversation with weekly updates and illuminations regarding progress in the marketplace. He actually works behind the scenes making sure that your property is listed everywhere, every week. Needless to say we are very pleased with Geoff as a person and our realtor. I guess I need to say one more thing. And that is, that he knows what he's doing. Geoff has been a realtor for a long time, but being an active member of the Claremont community means he just knows how this place works. Therefore, has knowledge invaluable to all parties involved in real estate transactions. Thanks to Geoff.

                        - Genelle Peterson, Padua Hills, Claremont
                      • I have known Geoff Hamill professionally since 1995, through several real estate transactions, and I have referred numerous friends to him with no qualms. A lot of the professional work I've done in the last 27 years entails assessing the credibility and character of people, and I cannot praise Geoff more highly. He has always been scrupulously honest and ethical. He tends to be detailed-oriented so that nothing "slips by" him. He is also just a nice human being; I cried in front of him a couple of times when selling my much-loved house in Claremont last summer and he understood. Once, years ago, I was thinking of buying a property in Indiana. I just asked if he knew anybody in real estate in Indiana who could be my agent, and he worked for three days looking for someone with top qualifications for me. In addition, because he has worked in this general area for so long, his personal knowledge of the area is impressive. For instance, he knows the personalities of the other brokers or agents in the area, so he knows who might try a maneuver to try to gain an advantage. He also knows the best local mortgage brokers, title companies and escrow companies in the area, and they know him, so business dealings go much more smoothly. He also knows honest and reliable local companies who can help with the many,many little things that need to be done, such as termite companies, roofers, movers, etc. For instance, when I was a selling my house in a heat wave last summer, the air conditioner suddenly went out, but an experienced repairman he knew showed up in 20 minutes and everything was fixed within one hour. I am a person who has no problem complaining loudly when warranted, but I also go out of my way to praise good service. Obviously, I cannot think of anything negative to say about Geoff and I recommend him most highly.

                      • Over the years my husband and I attended many open houses in our quest to keep up with the housing market. During that time we had meet Geoff on a lot of those occasions and always found him to be knowledgeable, respectable, and fair to both the sellers and the buyers. When we decided to put our house up for sale in order to pursue our dream of owning an old home, we knew that we would list it with Geoff. He was very patient with us and allowed it to happen on our time (we had to complete a bathroom remodel, my husband was ill, and we wanted to weather the holidays before listing it) He sold our house in Jan '13 in 4 days with 5 offers over the asking price. He even helped us in weeding through the offers so that we would have a smooth transition into escrow and an easy move.We had to move to a rental (behind the freeway) in order for us to have the time we wanted to find the perfect house. It wasn't easy and many times I came up with crazy ideas but it was Geoff who was the calm in the storm. Always there returning my calls or emails with confidence and reassurance that we would find our dream house. And boy did he ever! He found the perfect house with everything we wanted.Unfortunately, it had everything everybody else wanted as well! There were 5 other competing offers and It was Geoff who helped us make our offer one that the sellers couldn't refuse :) We've been in our "new" 1923 house now for 5 months and I owe it to Geoff for helping us make our dream come true. At no time did we feel used or manipulated. He is the utmost professional (and can take a great teasing too!) and takes great pride in making sure every detail is covered. We knew that on both transactions nothing would come back to haunt us. I cannot recommend him highly enough!.

                        - Wendy H, Ontario & Claremont
                      • We have used Geoff for 4 separate real estate transactions. In each case, he guided us through the process with professionalism and expertise. All the transactions were timely and relatively painless. Geoff handled everything from negotiations to inspections, and we just signed the forms. We would highly recommend him for any real estate transaction.

                        - Jeff Stark, Claremont
                      • Geoff and I have worked together for about twenty years, and he is, exclusively, my real estate broker, both as a buyer's broker and a seller's broker. He has also helped me with other real estate issues, not related to buying and selling a home. I have always known him to be unswervingly honest, ethical and professional and would recommend him without reservation. I saw a review once from a man who was furious that Geoff would not dump a client and go with him, even if it meant more money for Geoff. It was clear that this man had no idea of such a thing as ethics. In short, Geoff is absolutely great.

                        - Barbara S., Claremont & Pomona
                      • Geoff Hamill was our real estate agent for the sale of our house in the Spring of 2015. We were very pleased with Geoff and his team -- they were easy to work with, very knowledgeable, and responsive. Geoff helped us work with multiple offers, and we were pleased with the results -- everything was very smooth and Geoff facilitated a quick settlement. We now live out of the area, but would recommend Geoff to others around Claremont and Upland.

                        - David F., Upland
                      • Geoff, Thank you very much; I was happy with our sale association. Sometimes buyers/agents can be a pain, but you were not. Thank you for handling things very professionally, as I knew you would for my Claraboya property. Best to you, Sharon Hightower 798 Via Santo Tomas, Claremont

                        - Sharon Hightower, Claraboya, Claremont
                      • Geoff was great to work with. Totally professional and very responsive to my preferences. Found the perfect place for my needs and budget thanks to him. Well done!

                        - David Day, Claremont
                      • Geoff is exceptionally experienced and professional! He helped us find and buy our dream home and he helped us sell our house without a hitch. I would recommend Geoff to everyone!

                        - Jennifer Stark, Claremont
                      • I appreciate Geoff Hamill as a realtor and a steward for the community of Claremont. His knowledge and level of service in real estate is exemplary. He was able to uniquely support my complex and dynamic home selling needs with patience, understanding and flexibility. His familiarity and connection to Claremont, its history and community goes back 2 generations. He understands the nuances of Claremont's neighborhoods because he is and has been a member of the community his whole life. This mattered when I sold my home. It was important to consider the people involved in the process as well as the local market. Geoff Hamill is as unique to Claremont real estate as Claremont is to Southern California. If you're looking to buy or sell in Claremont, I suggest you first talk to Geoff Hamill. He is an exceptional realtor and resource.

                        - John K., Claremont
                      • We feel very lucky to have had Geoff represent us with our recent home sale. He is extremely knowledgeable, organized, and available to answer any questions and guide us on a smooth sale. He was even willing to listen and offer advice on our home we were buying out of the area. We felt like he genuinely cared about our family and truly wanted the best for us!

                        - Laurel Eldredge, Claremont
                      • Geoff Hamill is an amazing Realtor. His extensive knowledge and experience in the real estate market helps him guide his clients through what could be a complex process, but which he makes a simple direct procedure. In fact, I choose Geoff as my realtor because of his 25 year experience selling homes in the Inland Empire.He has an extraordinary team of skilled service people, helping his clients make their property the best it can be. When Geoff sold my parents' property in Ontario, it could have been a long process, instead everything went very smoothly.Geoff is exceptionally responsive to the needs of his clients. He informs his clients of the process, and keeps everything on schedule. He always promptly responds to phone calls or emails.I felt totally confident in Geoff' s abilities and was very pleased with the results. I am proud to recommend Geoff Hamill as an outstanding "full service" Realtor.

                        - Mary Chamberlin, Claremont & Ontario
                      • I've known Geoff Hamill as an expert in real estate in the local Foothill communities for many years. If I know someone looking to buy or sell I always refer them to him for advice because I know he will be honest and straight forward about any situation. He has a passion for his job that radiates through professionalism and a sincere interest in helping people with their real estate needs. I can tell he is truly happy doing what he does and that money is not his only drive for his business decisions; but more so the happiness and taking care of the concerns of his clients. Knowing his Mother Ruth Hamill was also in the business for many years, she taught him well and raised a true gentlemen that exudes the highest integrity at every level.Rest assured Geoff will check every "t" and dot every "i" twice to make sure your best interests are always protected!

                        - Michael M., Yorba Linda
                      • "We can tell you without reservation that it's been a wonderful experience working with Geoff Hamill! We called Geoff because we'd seen his signs on properties around town that not only sold quickly, but sold close to or above asking prices. As we asked around, we heard nothing but praise for Geoff's expertise. We had our first meeting with Geoff as we began to consider a move from our Village Walk loft to either a house or condo. We were really looking for a mid-century modern property and knew we'd have to wait for the right property to become available. Geoff never lost sight of our goal and was there for us every time we called with a question or a request to view another property. Geoff's counsel was wise and measured. His patience was immense! He taught us how to get what we wanted, both as we sold our First Street loft and as we bought the High Point property. We have the utmost respect for his integrity and intelligence. Wheeler Steffen/Sotheby's Int'l. Realty is so fortunate to have Geoff on their team. We can't say enough good things about our experience from beginning to end. While we hope to stay at High Point for years and years to come, if we're ever in the market to buy or sell again, we know who to call....and we're happy to share our experience with others as well."

                      • Believe it OR Not! It's about time I write this review. Geoff Hamill has helped my family with 4 transactions over the last 15 years and no matter what we threw at him (divorce, new life, downsizing, retiring) Geoff's integrity, experience, knowledge and professionalism has enabled him to overcome it all and succeed each time, on-time, on-target and on-budget to satisfy all of our family's needs. Geoff is a true pleasure to work with. I can highly recommend Geoff Hamill to address all of your needs (lol)... Have a great day!!

                        - Marsha W., Claremont
                      • I highly recommend Geoff as a listing agent. He was very good representing us, the sellers, and worked extremely well with the buyer's agent relating to the sale of our house in the Deer Creek area of Rancho Cucamonga. It was such a nice way to begin and end the process. Our escrow took longer than usual and he did an excellent job protecting our interests. He is in close contact with the stager they use and the escrow company and it helped smooth out the process of listing and selling our home. He has continued to stay in touch with us as we've made the transition out of this house to another home. We had interviewed a total of six highly recommended agents and I remembered meeting Geoff at a showing in Claremont 20 years ago and wanted to interview him again. He was the obvious choice. He is very experienced and I am glad he was our agent.

                        - Lillie C., Rancho Cucamonga
                      • With so many, many Realtors to choose from, it is rare to meet a real estate professional with the same integrity as that of Geoff Hamill. We have purchased property from, sold property through and acquired tenants via Geoff for nearly 20 years. Every transaction has been very satisfying, completed on time and has never included a surprise. That is extremely rare given all of the variables in conducting real estate transactions. We have never been disappointed in dealing with Geoff.

                        - Charles and Rosario Gerlach, Claremont
                      • I would highly recommend Geoff Hamill for your Realtor. His commitment to helping you sell your house is excellent, as we found out when he helped us sell my moms house. At all times he was right there when we needed his expertise.Michele
