Thank YOU Brent!! Brent was fantastic during this entire process. Always making himself available, giving us solid advice, finding us resources out of your network of people, being cautious when we needed to be and pushing fwd when the time was right, pulling out ALL the stops to get letters of recommendation from neighbors and pushing our offer to the top in a ultra competitive market and moving quickly late on Sunday nights when we said we needed to make an offer by 12pm on Tuesday. At every turn, we felt your confidence and your EXTRA effort. We couldn’t recommend you more to others and grateful you were part of our home buying team. Great job Brent!

Chris Dempsey and Jessica Cruz - Novato Home Buyers

Brent exceeded all our expectations. He not only gave us excellent advice and direction on what to do to get our home ready to sell, he recommended excellent people to do the work at very reasonable cost. He was knowledgeable about how to price the home, and was instrumental in getting the house ready to put on the market more quickly than we could have ever imagined. The entire process was so easy thanks to Brent. We ended up getting $56,000 over asking price. We would highly recommend Brent to anyone selling their home.Brent exceeded all our expectations.

Marty and Katie Dunn - Novato Home Sellers

Brent is the BEST! He was referred to us by close friends of ours who recently bought a home. We contacted Brent early on in our home buying process and he was extremely knowledgeable and professional. We are first time home buyers and the entire process was new to us. He walked us through it every step of the way. His communication was excellent and answered every single question we threw at him. He went above and beyond by finding us an unlisted property in our dream neighborhood! We highly recommend him to anyone looking to purchase a home. We not only found a realtor for life, but he has become a great friend.

Deanna and John Fahey - Novato Home Buyers

We worked with Brent to buy our new home, and sell our first home, here in Petaluma. Working with Brent was an absolutely wonderful experience. Brent was very responsive, great in the negotiation process and very helpful in helping us navigate both the home purchase and home selling processes. Around every twist and turn, we felt confident in Brent's advice and knew he had our best interest at heart. Through the buying and selling process, we needed several service recommendations, and each company/person Brent recommended did excellent work and came through at an affordable price. We would highly recommend working with Brent and would 100% work with him again. However, since he helped us purchase the home of our dreams - that won't be for a while!

Karli and Scott Warner - Petaluma Home Buyers and Sellers

My wife and I could not have asked for a better realtor and guide through our venture into home ownership. We were demanding clients who didn’t really know what we wanted at first. Brent was incredibly patient with us (and our unrealistic expectations) and helped us narrow our search down to properties that made sense for us. Brent is the type of guy who knows someone everywhere he goes and you instantly become friends with. Brent was able to leverage his vast relationships in the community to provide us with opportunities we would not have otherwise found. As a buyer in this market you need every advantage you can get and Brent was able to provide that for us by getting us into homes before they hit the market. We ended up purchasing our home off market and Brent was able to facilitate a fair deal that made both us and the sellers happy. During escrow Brent handled all the legwork for us on site as we did not live in the town we purchased in. Again he used his relationships to gather repair estimates during the inspection contingency in a tight time frame to keep the process moving. While Brent was excellent in the search process, he really shines when you get down to negotiations in escrow and we were confident in the representation he provided us. We could not be happier with our new home, and who got us in there. Thanks Brent!

Nick and Lindsay Misakian - Petaluma First Time Home Buyers

No matter where you might be on the home-buying/home-selling spectrum, you will have no better guide, ally or expert to help you than Brent Mosbacher. In selling our home we had the added element of being a Company Relocation. This requires a great relationship with an additional 3rd party Relocation Company, as well as completing a number of requirements and additional paperwork. Brent stayed on top of all the tasks and allowed us to focus on our move to a different state. Brent was responsive to each and every one of our calls, he does his due diligence in knowing exactly what to expect in the constantly changing real estate market and give us sound advice on the best plan of action. We got outstanding results; our home was only on the market for 9 days and received three offers all over the asking price. With his diligence and professionalism, we were also able to reach a successful closing for all parties in just 22 days. If you need someone who will work hard for you in buying/selling a home, you need to do yourself a favor and add Brent to your team!

Cindy and Randy Plumbtree - Petaluma Home Sellers

Having just purchased our first home through Brent Mosbacher, I can happily say that he was terrific through the process and terrific to us. He was very responsive, hard working on behalf of us the buyer, and knowledgeable. He noticed little details my wife and I had missed and worked with the seller to get the items right before move in. If you're not sure where to start when picking an agent, I recommend giving Brent a call: he is caring, direct, and not-aggressive or inpatient. Being first-time homebuyers, we were incredibly grateful to be working with him. Thank you for everything, Brent!

Stephen and Elizabeth McNeil - Petaluma First Time Home Buyers

Brent was great. He was very knowledgeable about the Petaluma area and was able to tell us about all the areas we looked. He was basically available 24/7 to answer questions we had or to meet with and tour homes. Brent is a very personable agent and easy to talk to.

Mike Langford - Petaluma Investment Home Buyer

Brent was nothing short of incredible to work with during the process of purchasing our first home in Petaluma. He turned what I thought would be a stressful and scary process into something easy and enjoyable. Brent had a clear answer to every question I had along the way and he repeatedly went above and beyond the call of duty to help me in any way possible. Brent's vast knowledge of the real estate business and local listings was incredibly valuable and helped us to get our offer accepted on our dream home. Overall, Brent is not only professional but also incredibly nice and caring. There's no one better to help with your real estate needs.

Adrian Lahey - Petaluma First Time Home Buyer

Brent is the one to call when buying or selling real estate in the North Bay. He understands the market, he understands the importance of negotiation, and he understands the need to follow up. Always available, always helpful, and always professional describes Brent. He does what ever it takes to work through the many issues that come up when buying and selling real estate. Having bought and sold more than 20 properties, I consider Brent the most skilled Realtor I have worked with.

Sandy and Tib Warner - Petaluma Residents and Property Investors

We recently bought a house with Brent's help. We are very impressed with Brent's attention to detail as he remembered the criteria that we were looking for in a house. He often recommended to us the house that was very close to what we were looking for. Brent also did his best to to meet our requests in viewing the houses that we were interested in sometimes with a short times notice. Brent showed his professional skill in real estate during the purchasing process. We were given very useful advice and recommendations about things we never thought of! He always follows up on our requests and gave us updates in a timely manner. Overall we had a very good experience with Brent. The purchase of a house can be a stressful experience, but working with Brent has made this experience much less stressful. We love our house, thanks Brent!

Chyehar and Keith Tyler - Rohnert Park Home Buyers

Brent was an absolute pleasure to work with while purchasing our home! From start to finish he was extremely professional and kept open lines of communication that made the entire process run smoothly. Brent's knowledge, and insight into this competitive market undoubtedly helped our offer stand out above the rest. His negotiation skills played a major role in us receiving credits post-inspections. We cannot emphasize enough- Brent made every effort to ensure we were happy. When we picked up our keys, we were pleasantly surprised with a heartfelt note along with some gifts to help get settled into our new home! We highly recommend Brent Mosbacher for any of your real estate needs

Scott Mosbacher - Pleasant Hill Home Buyer

Brent was so great to work with. We saw a house on a Friday, wanted to see it again on Saturday and needed an offer in by that Tuesday. We only had a pre-approval and needed to get a lot done by Tuesday in order to submit the offer and Brent made it happen. He referred us a great Loan Officer and both of them worked non-stop to make sure we could submit an offer. He also advised us very well, took comps into consideration and made sure we weren't over paying. Even in a seller's market. Brent will definitely be selling our house (hopefully not for 30 years tho :-)) and I'd refer him to everyone I know.

Kari and Nick Humphrey - Petaluma Home Buyers

We want to acknowledge what a wonderful experience we had with Brent as he guided us through the process of purchasing our house in Petaluma. He was very knowledgeable of market conditions and was our advocate handling all the documentation. His attention to detail and his ability to negotiate with the sellers was invaluable.

Brendan and Sue O'Leary - Novato/Petaluma Investment Home Buyers

Super job Brent! Professional, knowledgeable, and friendly. Highly recommended. I've known Brent for ten years, and he is the best. He is hard working and responsible. I invest in residential and commercial real estate, and he is great!

Clayton Zeidler - Real Estate Investor

Brent was great to work with! He was always available for all my questions and requests for viewings. This being our first home purchase in California after relocating from the east coast he was very helpful in the areas that were new and/or stressful for us. He always had a positive attitude even when I was getting discouraged when we couldn't find what we were looking for. He went way above and beyond to make the whole process less stressful for us. And in the end, we found our perfect place!
