Costanza helped us every step of the way. She knew selling our parents' home was going to be an emotional journey for us. And, with one of the siblings living in another state, she helped explain every form we had to fill out, the processes we were going through and reasons why, what the pricing that the current market was dictating, and which offers to truly consider. She was very patient with us. And in the end, got us over asking price, and a smooth escrow. Her experience and professionalism were a great asset to our family.

Costanza works harder than anyone else. Her knowledge of all the aspects of buying/purchasing a house is un matched and she taught me so much as we went through the process. I was a first time homebuyer and having someone who could really explain to me the areas, options and what to expect was key. I feel extremely lucky to have found her. I trusted her completely and have a wonderful home because of her.

Costanza was super helpful through the process of buying my home. She was helpful and gave me insight on what she thought to prevent me from overpaying. She was extremely responsive and made herself available to discuss concerns I had during a major holiday. I highly recommend her and would use her again without question.

I knew from the minute Costanza arrived at our house that she would be the one. She exudes an air of confidence while remaining personable and friendly. She's professional and does everything possible to get the house ready for sale without breaking the bank. She told me more than once not to spend money on 'that' (whatever my concern was at the time), and yet wasn't hesitant to help us see where we should spend money. Costanza was easy to work with and very helpful. We had already moved to a new town, and couldn't have done it without her assistance. She will always be a friend - it's hard not to enjoy her company. I highly recommend Costanza Genoese Zerbi and her excellent associate, Neil Edmonds, whether you're listing or looking to buy. You'll want to thank me in person. :)

When the decision was made to sell, we interviewed several agents and immediately knew it would be Costanza! She is an incredible communicator. We were never on pins and needles waiting for any answer, and she was very clear and straightforward with any information passed on to us, whether good news or not so good news! Her thorough knowledge of the industry, coupled with the team who surrounds her, made for a flawless process. Costanza has become a friend and we would never hesitate to use or refer her services in the future.

I had the absolute pleasure of working with Costanza on the sale of my triplex in Long Beach, and I cannot recommend her highly enough. From the very beginning, she brought professionalism, deep market knowledge, and an incredible level of commitment to the table. She guided me through every step of the process with clarity and confidence, offering thoughtful advice and smart strategy that ultimately led to a successful sale. Her attention to detail, responsiveness, and strong communication made the entire experience smooth and stress-free. What impressed me most was Costanza’s ability to balance professionalism with a warm, personal approach. I always felt that my best interests were her top priority, and that trust was invaluable. If you’re looking for someone who genuinely cares, knows the market inside and out, and gets results—Costanza is the one to call. Thank you again, Costanza, for everything. You exceeded every expectation!

We were involved simultaneously in selling & buying a house. It involved 3 realtors. Costanza clearly out performed the other two from where we sat, not by a little. The only agent we will ever use or recommend moving forward. We are grateful to Costanza now in two house buying and one selling experience.

During our six-year relationship with Costanza, we have witnessed an exemplary individual who is dedicated to excelling in all of her professional dealings through a knowledgeable and strong work ethic, while always displaying the utmost respect towards her clients. Costanza, above all else, is a family-oriented person who has always conducted and presented herself with a polite demeanor and levelheadedness in her judgement and all her dealings. My wife and I were moved eight times during my career. In every case we worked with a top realtor in the market. In many of those markets the realtors were good but none approached Costanza. Simply stated Costanza stands out as the very best realtor we have ever dealt with, anticipating our needs, being extremely well organized and assisting us in both finding our ideal home and utilizing her extensive local market knowledge in getting our family settled as quickly as possible. My wife and I highly recommend Costanza to anyone who is moving to the greater Long Beach area or are selling their home. Ps – Costanza also sold our home in less than one week. She marketed our home wonderfully well, attracting two buyers, resulting in us getting a purchase price above our asking price. She simply is “THE BEST.”

Working with Costanza has been an absolute joy! As a veteran in the industry, her deep knowledge and understanding of the market were evident from the very beginning. As a first-time homebuyer, I initially felt overwhelmed by all the complexities involved in purchasing a home. Costanza was incredibly communicative and thorough—she took the time to explain every step of the process clearly, which helped me feel much more confident and at ease. I truly appreciated her guidance and support, and I’d wholeheartedly recommend her to any buyer or seller in the future!

Working with Constanza was a fantastic experience from start to finish. She was professional, knowledgeable, and always responsive, making the entire process smooth and stress-free. Constanza truly listened to what I was looking for, provided valuable insights, and guided me every step of the way. I appreciated her honesty and transparency, especially when it came to pricing, which ended up being right in line with my expectations. I couldn’t have asked for a better agent and would highly recommend her to anyone looking to buy or sell a home.

Costanza helped me sell a condo in Agoura that belonged to my late sister, as I am the successor trustee of her trust. Costanza’s extensive network, negotiating skills and understanding of the market enabled me to sell the property quickly for a good price. She is super responsive and an extremely hard worker. She also listed another property in Chatsworth that belonged to the same trust, and created a bidding war resulting in the trust receiving a great price for the property, despite it having significant deferred maintenance.

I had a great experience working with Costanza to sell my house. She was professional, responsive, and guided me through every step of the process. She priced the home well, helped with staging and marketing, and got us a strong offer quickly. I really appreciated their clear communication and honesty throughout. I’d definitely recommend her to anyone looking to sell their home.
