WHAT CLIENTS SAY ABOUT JEAN MASTAGNI
"We have known and worked with Jean Mastagni for over 35 years. Jean has helped us buy and sell many properties over that time. The most recent of those has been the sale of our Tiburon home for $3 million and our Lagunitas home for $995,000.
Jean represents the ultimate essence of professionalism, loyalty, respect, honesty and dedication in her role as real estate agent. We have many more properties to sell and we wouldn't use anyone except Jean". VA & AA
"I was introduced to Jean Mastagni many years ago when she represented a house for sale that she had originally sold to the same owners. Of course, she did because once you work with her, you will always use her again and again. I was so impressed with Jean in that buying process, that when I was not the winning bid on the house, I fired my agent and hired Jean. My experience with Jean through buying and selling of properties since then has always involved Jean because as a Realtor she walks on water.
I know of very few agents that are as thorough, as professional, as kind, as giving, as consultative, or as savvy at Jean Mastagni. She has and will represent all my real estate transactions, and the last house I sold this past spring was the icing on the cake. Nobody could believe how Jean managed the process in such a way as to set a record for price per square foot sold in Marin. Jean's work was impeccable, as every single little detail was managed with not only lovely style, but with absolute charming grace. To say she is talented and special just doesn't capture it because she is actually well beyond that water mark. Jean always goes so far over and above the call of duty during and even after the process that you would never for a second doubt the commissions were more than worth it.
If you are considering an agent, I suggest strongly that you put your faith in Jean. Should you have any hesitation at all or any questions, feel free to call me any time to ask me specifics. Best of luck". BM
“In 2013, I had to sell my beloved Mill Valley mansion, which was a well-known and favorite home of many Mill Valley people.
It was a difficult task to let this property go. I was fortunate to have Jean Mastagni as my listing agent. Jean helped me prepare the home, the large garden and grounds and the Disclosures, so that when an all cash, full price offer came in, within 2 weeks after the on-market date, we were able to close the transaction within 21 days as the buyers had requested.
I have worked with Jean in the past. She is the only broker that I would engage to sell or buy a home, because of her efficiency, expertise, and assistance from listing date through close, and as needed after the closing. She is a continuous source of help. She also knows how to position a seller to their best advantage and makes sure that fine details are not overlooked. Jean represented me on the purchase of this home in the year 2000 when there were 7 other competing offers. My home sold in excess of $4,000,000. Prior to that sale, Jean represented my family in both buying and selling another Mill Valley Estate. The sale also yielded more than asking price with multiple offers, which Jean skillfully engineered from beginning to a rapid, smooth closing.
It is a pleasure to work with her and Jean is a class act”. JOR
"I know "J" already sent you her thanks and appreciation, and I just want to add mine still again. I mean it when I say that you did more than I could have expected with more patience and more diligence and more care. We certainly will gladly recommend you if we get the opportunity. May all go well for you, M."
"Jean Mastagni introduced me to a stager who in coordination with Jean accomplished subtle but effective changes to the look of a house I had always found comfortable and welcoming, but I watched acquire striking appeal. Regarding the overarching problem with the front of my property, by now the lack of any progress had me alternating between futile rage and equally unproductive impotence and I turned to Jean Mastagni for help. She did not disappoint. I have always considered myself a capable person in the business world, but her skills are on a different level. In her dealings with this array of difficult individuals, she combined the voice of a seasoned diplomat with the backbone of a Navy Seal. Result: the front of the property was cleaned up and presentable in time for the Broker's Open. And the successful purchase bid quickly followed.
I am writing to congratulate Coldwell Banker on having a broker of the caliber of Jean Mastagni. She is not only very effective in reaching the desired goal, she makes the process of achieving that goal not just tolerable, but enjoyable."
"Hello Jean - I've been so busy with all of the home business and my self-employed business that I haven't had time until now to thank you so much for all the effort you have put out regarding our potential purchase. I believe you have gone way beyond what I would have expected in both info finding out and patience with the whole process. I now see that when the seller's agent is not quite as good as the buyer's that there can certainly be problems. I wanted you to know from me that your efforts were noticed and appreciated very much. Sorry it didn't work out (I've let go of the bathroom there three times now - as well as the view). We'll be in touch. JMD"
"So many thanks for holding my hand and all your efforts to get this deal done - including Staging with your own possessions - delivery and pick-up! You are awesome!"
"I just wanted to take a minute to acknowledge your efforts in the recent sale of our house in Sausalito, and to thank you."
"Now that we closed on the sale of our house, and are about to leave for the east coast, I have to tell you that we could not have been any more pleased with you and your efforts. I have bought and sold many houses and have never had such a wonderful agent experience. Your willingness to work for us had absolutely no boundaries, and your focus on the sale of our property never faded even for a minute. I am convinced no other agent we talked to would be willing or able to put of the kind of energy into the sale of a piece of real estate the way you did. Because of your efforts, we were able to leave town during the showing and sales process, and not have a single worry. I know you think I even checked out a bit when we went back east when it was listed, but it was only because you had complete control and we had complete confidence in you. When issues did come up you handled everything perfectly, so there was very minimal stress if any for us to deal with. We know your reputation is of an expert, knowledgeable and honest agent, and we feel we benefited from those traits, especially when we closed for more than asking price."
"Our home was a reasonable high-priced property with an asking price of approximately $3 million. We were under some pressure to get this done on a timely basis as we have an impending move to Colorado. Jean did an excellent job of getting the transaction done on a very compressed timetable without sacrificing any of the value we expected to garner on the sale. Neither my wife nor I could devote our full attention to the process and Jean really lead the effort from start to finish, even working with many of the tradesmen that were required to get the property ready for showing. This was no mean feat as we have several small children. Jean was nonplussed in dealing with their daily efforts to return the house to a more “lived-in” appearance."
"I want to tell you what a pleasure it was to work with your office in the recent sale of my property in Tiburon. I particularly want to commend Jean Mastagni for her diligence, wise counsel, and hard work, going far beyond the call of duty and, in the process, obtaining a sales price far above my expectations. Jean does credit to both your office and your profession."
"The purchase of this property was not straightforward and there were many obstacles to overcome, which necessitated a "true pro"."
"Through determination and expertise, Jean somehow miraculously managed to deliver a palatable determination, so that we finally felt comfortable in consummating the purchase of this wonderful property with the exact views of San Francisco that we had envisioned. Jean kept a clear head throughout and called upon her resources of experts to solve mysteries that seemed impossible. We were almost ready to throw in the towel, when suddenly the answers we were seeking came forth with clarity, as a direct result of Jean's abilities, diplomacy and vast experience."
"I would like to thank you for all your hard work on this transaction and your support. You have been a tremendous person to represent me throughout the process, your level of knowledge and professionalism is unprecedented, and I am very glad to get to know you."
“In the beginning Jean was simply our “Realtor” but as time went by she quickly became our trusted friend. When we purchase our home, she represented the seller as well. We always felt our best interests were being met and, in fact she continually surpassed our expectations. What could have been a stressful time was a joy because of her professionalism. The most marvelous thing about Jean is that she goes above and beyond what is expected.”
“You just don’t find service like that anymore and she deserves to be recognized for her excellence.”
“Words can’t express our gratitude! Without you, we wouldn’t have had a housewarming. We’re very grateful for all you’ve done. Thanks for making it all happen!”
“Words can’t express our gratitude! Without you, we wouldn’t have had a housewarming. We’re very grateful for all you you’ve done. Thanks for making it all happen!”
“I just wanted to write to share with you what a wonderful buying experience I had with your associate Jean Mastagni. We had a delightful four months locating and purchasing a property under her guidance. Jean’s attention to detail and follow-up were extremely thorough and much appreciated.”
“I am very comfortable in recommending Jean’s services to others upon request.”
“We have purchased a number of properties over the years, but neither one of us has experienced the level of energy and professional skill that Ms. Mastagni brought to our transaction.”
“Jean brings an attention to detail and enthusiasm that you would assume characteristic of an owner. Jean by any standard afforded us peerless service and attention. Jean did a superb job, and we would —and have recommended her to friends and acquaintances.”
“Jean stayed with me through thick and thin. There were problems in all areas, but she forged ahead with me until the house was sold. There would not have been many agents that could have put up with all the aggravation that presented itself. I felt very fortunate to have her in my life both as a real estate consultant and as a fine person who I grew to like immensely.”
“I recently purchased a house in Belvedere, and I just want to say how grateful and impressed I was with the help offered to me by Jean Mastagni.”
“Jean not only handled all the paper work involved with great speed and efficiency but was largely instrumental in keeping the negotiations alive when I had almost given up hope of obtaining the property. The result, I now own a house on one of the most magnificent sites in the Bay Area (and indeed arguably anywhere), and the sale went through in record time, and at a very fair price. I cannot praise Jean Mastagni highly enough and would certainly recommend her services to any of my friends interested in buying or selling property."
“Jean is a very professional, thorough and efficient real estate specialist. Her communication skills were extraordinary, and I would not hesitate to recommend her or to call upon her for future real estate transactions.”
“I consider myself lucky having met and working with Jean. I strongly feel you, too, are fortunate to have Jean on your staff.
“I highly recommend Jean Mastagni as a real estate broker for anyone interested in selling or purchasing a high-end home in Marin County.”
“Jean had the right balance of being professional, personable, hardworking, ethical, well networked, clear headed, sophisticated without being stuffy, and able to relate well to buyers of expensive properties (even the ones with rather challenging personalities). She was also well respected and liked by the other agents in the county, which I knew was very important to conclude a smooth and cooperative sale.”
“Jean was very thorough in her approach to advertising, marketing, presentation, and follow up. She was always available and worked very diligently to cover all necessary bases, and to keep me fully informed about everything that was happening during the sale process which took about 18 months.”
“I recommend Jean without reservation as “First choice” for a real estate agent in Marin County.”
“The wisdom in choosing Jean to handle the sale was confirmed when we closed the sale after about three months from the time it was listed. Jean showed a lot of patience, sensitivity and dedication in pursuing prospective buyers and in keeping in touch with us by long distance calls and faxes to Manila. My wife and I are very pleased with the service she has rendered.”
“We would not hesitate to recommend Jean to anyone who may be selling or buying upscale homes in the Marin area.”
“Jean is a person with the utmost integrity and high moral standards. Her accomplishments are many and her business policies are admirable. She has achieved a great deal of success and respect in the community and takes great pride in being impeccable.”
Please file this letter in praise of Jean Mastagni.”
“Jean Mastagni called us each and every day, professionally exact in answering our questions, supportive of us emotionally and representing us (and Coldwell Banker) in her charming and completely professional manner.”
We were pleased to work with a professional with such a high level of experience and knowledge and look forward to future dealings with Jean Mastagni. We wouldn’t hesitate to recommend her services to our family and friends.”
“Right about now I consider myself a very lucky person because I had the good fortune to sell a home and buy a new one in Sausalito all within six months thanks to the skill and expertise of realtor Jean Mastagni.”
“Jean deftly guided me through the process of selling my home and took care of all the details and paperwork. Then she conjured up all her contacts and skills to find the perfect house for me in a very short period of time during the off season (December and January), which went through without a hitch. I still can’t believe it all worked out so well, and I attribute it all to Jean, her knowledge of the real estate market and business, and her extraordinary ability to deal with many different kinds of people.”
“Too say that I am a satisfied customer is an understatement, and I unequivocally recommend her to any of your future clients.”
Selling a home can be a painful and fear-producing experience. Fortunately, we chose Jean Mastagni and Coldwell Banker to help facilitate this process as our agent and broker (and, occasionally, our therapist). Jean’s professionalism and focus on the details helped to assure that the sale was expeditious. But, more importantly, Jean was sensitive to the emotional nuances of both the buyers and sellers to assure that everyone was truly getting what they wanted. Jean’s mix of emotional support and professional guidance helped this sale occur without a hitch. She was a real pleasure to work with!”
“I appreciate and am grateful for your efficiency, professionalism but most of all your lovely spirit!”
“We are writing to express our appreciation for the very professional and expeditious job Jean Mastagni did in assisting us with the sale of a residential property held in trust. Ms. Mastagni coordinated many details to prepare the home for sale making the process as simple as possible. We would welcome the opportunity to work with Ms. Mastagni in the future.”
“Ms. Mastagni proved to be outstanding in every respect. She showed herself to be a consummate professional with a deep sense of responsibility, honesty, integrity, magnanimity, ability to close a deal, efficiency, knowledge and intuitiveness; but most of all, she put her clients interest above all else.”
“We have had in our lifetime, a number of occasions to utilize the services of real estate professionals, she was unmistakably a cut above the rest. Right from the outset, it was clear that it was not IF but WHEN she would put us in a suitable property. She had transformed a mundane process with potential Excedrin headaches into a pleasant experience.”
“I have at all times found Jean to be most professional. She has been very easy to work with. She is prompt, has reliable follow-through and has evidenced sensitivity to my needs and desires. I know her to be industrious, and she possesses a high degree of integrity. I do not hesitate to recommend her services.”
She is highly qualified, thorough and competent professional who well represents your organization. Throughout the handling of my property in Mill Valley she was always well informed, persistent and imaginative.”
“You have no doubt already heard these things from the many people Jean has worked with. All of the praise is well deserved.”
We have found Jean Mastagni to be highly ethical, energetic, straightforward, dependable and professional at all times. She has demonstrated a great passion for our Tiburon home and always illustrated its’ alluring qualities to its’ best advantage, was prompt for showings and presented herself in an impeccable fashion.”
“Jean’s capabilities are many and we would not hesitate to recommend her, particularly in the area of luxury homes in Marin County.”
“Recently my husband, and I had the good fortune to buy a magnificent house in Mill Valley under the excellent auspices of your associate, Jean Mastagni. Quite simply we could not have bought that house as fast and as painlessly without her excellent steady hand guiding the wheel.”
“Could any deal have been more perfect? I wouldn’t doubt it if Jean Mastagni was in charge. What an absolute treasure this woman is. I simply cannot heap enough praise upon her and have already recommended her to several friends about to embark upon what everyone says is such a nightmare.”
“Jean Mastagni acted as my broker in two transactions in 1997. In the first of those transactions Jean acted both as my broker and the broker for the seller. Because of my trust and confidence in Jean in the purchase transaction, I also retained her as my agent in a subsequent sale.”
“I was impressed with Jean’s experience and accessibility. I have since recommended other potential buyers and sellers to her and would be glad to be considered a positive reference regarding her professionalism and skill.”
"Jean Mastagni handled a difficult and very sensitive sales transaction with outstanding grace and ease.
We have known Jean for 25 plus years and we knew we could depend on her abilities. She not only displayed a high degree of professionalism, but she also drew from her own personal style and experience. In our opinion, we believe those qualities are what set her apart from her colleagues in the real estate arena.
We will continue to recommend Jean to our family and friends for their real estate needs."
"Thank you for all your wonderful help getting us situated in Sausalito -you've been indispensable to us! We are so glad to have met not only a fabulous agent but a good friend."
“I have had the occasion to use the services of many real estate agents, none of which have been able to compare in excellence to Jean Mastagni, Associate Broker at Coldwell Banker.
I engaged the services of Jean Mastagni during the 1990’s and found her to be quite simply the finest realtor in the business and the best negotiator I have yet to encounter in any field. She has an uncanny ability to appeal to all types of people and to engaged them in such a way that they want to make a deal. She is aggressive with a tasteful restraint, which draws the pertinent together, rather than forcing them into a deadlock with improper emphasis and bad timing.
Jean is enormously gifted in creatively marketing properties. No opportunity ever goes by the wayside and her “dogged” persistence eventually provides the necessary climate to complete a sale. She follows through to the last detail with class and style.
She is the consummate Brokers’ Broker, admired by her own trade for her very high standards and abilities.”
