It is with pleasure and gratitude that I share my comments on our experience with Ester. This was our first time selling a home. Our situation was complex and lengthy Due to multiple family members being involved. Ester was patient. She took the time to get to know each of us. Ester was available immediately on the phone or texting. Some of the best advice she gave us was to fix up the home first before selling it. This paid off tremendously. Her expertise received in remodeling recommendations were spot on. During the remodeling phase, we welcomed her professional opinion's, as well as using the people she used in the past for various upgrades. They all worked out perfectly. Ester was very professional and personable. She clearly takes pride in doing a good job. In my case particularly as a home seller there were many rough spots on the road to closing and in every instance Ester was a great help. Ester was incredibly gracious to us through the entire process and we are grateful for her kindness, understanding, patience and expertise. Thank you Ester!!!

Ester is superb, high efficient and effective realtor and more importantly an even better individual. She facilitated the purchase of our new home as well as selling our condo. Ester is very detailed oriented and knowledgeable about the schools and the neighborhoods. Every step through the process, she would email, call or text us with a status. She would try to lift our spirits when our offers were not accepted by the sellers. Ester has great instincts when it comes to setting a strong bid for buying a house, but not at the expense of crazy overbidding as it is normally the case here the Peninsula. After looking for about 4 months, we bought a house in Millbrae which both the seller and us thought the price was reasonable and market value. Ester was the realtor who sold our condo in addition to helping us buy a home. She took care of all details relating to the sale, such as getting the required HOA documents, staging the condo, arranging for painting and cleaning the condo, and working on comparable for the listing price. In the end, the listed price she recommended generated 14 offers and we were extremely happy with the final results. We highly recommend Ester to any prospective buyers who is interested in buying a home and to any sellers who wants to put their home on the market. Ester will get you the best possible results on both buying and selling.

Ester was a pleasure to work with throughout the entire process. She was extremely helpful in our relocation across the country. She always had our best interest at heart, and was relentless in ensuring that all parties were on top of their action items. We ended up with a wonderful house that required quick action and a lot of coordination with the sellers. We couldn't have gotten this house without Ester. Highly recommend!

Ester was referred to us by our trusted realtor in San Francisco to help us find a house in San Carlos. We gave her specific parameters and a very small search area to find us our dream home within our budget and she expertly guided us to the finish line. Ester always remained positive and upbeat even when we had our doubts and buyers fatigue in this challenging market. Ester was always available to take us on tour, make inquiries on our behalf, responded quickly to our questions, and went far beyond our expectations. In just a few short months we purchased a house that we love and we couldn’t have done it without her. We valued her personable style and trusted her to negotiate on our behalf and she got the job done. We look forward to working with her again in the future and will definitely refer her to anyone who needs a realtor. Thank you Ester!

I wanted to sincerely thank you for all you’ve done for me as my realtor. From the beginning, you shared your knowledge with me and guided me through each step of buying my first home. You were also very patient and I felt supported by you throughout the entire process. Whenever I didn’t understand something, you helped to make it clear to me and were always transparent about sharing information. I know that it was challenging to work with my “non-negotiables” and I am grateful that you never lost sight of them. At the same time, you helped me to have an open-mind and to see this process in a different perspective. Thank you for keeping me focused and not letting me give up in this crazy market. Without your support, guidance, and patience, I wouldn’t be the proud first time homeowner that I am now! Please be reassured that I would not hesitate to refer anyone to you who is in search of buying a home.

We can't even begin to share how much we have enjoyed working with Ester-from beginning to end it has been a pleasure. Her professionalism, attention to detail, quick responses to our concerns and follow ups with our lender have really impressed us. She is a wonderful agent!"

We recently had the opportunity to work with Ester to orchestrate our family's move out of the Bay Area. Initially daunting, Ester helped us simplify the many processes involved in prepping our home for sale. We were simultaneously selling our home in Palo Alto and purchasing a home out of state, which required precise coordination between Ester and our out-of-state agent. They worked as a team to ensure that we were well positioned to leverage our sale here to facilitate our creation of a new life elsewhere. Ester and her team at McGuire were fantastic! This is a complex and aggressive real estate market and Ester showed facility and familiarity in her approach to comps and pricing. She has an expert eye for staging and was able to identify key easy fixes that we could perform in advance of an open house to present our home in the best light possible. She personally staged our home in a professional manner; in fact, we maintained the staging as long as possible because she created such an open and clean environment that we could not have done on our own! She also helped us obtain dependable 3rd party services when appropriate. For example, we needed a large amount of boxes and excess furniture moved to a storage unit offsite to enable staging. Ester connected us with a reasonably priced moving company and managed this move for us so we didn't need to take a day off of work. Ester quickly found us great referrals for short-term local housing and movers for our move out-of-state. Ester goes above and beyond. She is hands-on and responsive. We never felt alone or abandoned during this rapid-fire process, which included an open house with hundreds of attendees. She walked us through each of the multiple offers we received for our home and supported us the whole way through. If that isn't impressive enough, Ester stuck with us to facilitate the leaseback period included in the offer we accepted. We strongly recommend having Ester on your team!

Dear Ester, I want to thank you for helping me sell my condo in March 2014. Your professionalism and knowledge of the real estate market were of tremendous benefit to me. I have bought and sold five properties in the past and have never had such a smooth transaction. Your estimate of a good asking price and your marketing of the property created a bidding war that brought me a price of $50,000 over what I was expecting. When you called me that Thursday night with the seven offers, it was a dream come true. I felt good about the buyers and what they intended to do with the property and then, the next day, you said they had changed their offer to cash. I couldn't believe my good fortune. I loved working with you and must say you have changed a negative opinion of real estate agents into a great big positive. I wish you could come to Nevada and help me sell my property up here. I wish you all the best. Gratefully yours, Carole

Ester is a wonderful realtor. She served as our realtor when we embarked on finding our first home. She has considerable knowledge of properties in the South Bay and Peninsula. When the focus of our search changed to include East Bay properties, Ester worked collaboratively with another McGuire realtor to ensure our needs were met. She is kind, responsive, attentive, and knowledgeable. Since we were first time home buyers, Ester really held our hands and helped us through the process. Best, John + Maddy

We found Ester through our previous real estate agent's relocation department when we were moving from Washington, DC to Santa Clara, CA. With such a huge move, and a limited budget for relocation, we were hoping to find a realtor who could help us identify a rental property that would suit our needs without us having to fly out to look at properties ourselves. Ester worked with us to find a creative solution for our situation, and she did a great job of 'showing' us properties virtually. She is professional, prompt, and extremely helpful. We are so happy with the home she helped us find!

– Mary Hannah-Weir

Working with Ester was a pleasure ... she was always available and was able to anticpate what my questions and concerns would be. Ester is a true professional and works very hard to find properties that are a perfect fit for your needs. I will certainly recommend Ester to family and friends.
