      QuyNitta was an amazing agent for me as a first time homeowner. She walked me through the initial buying process and diligently stayed in touch until we were ready to buy. She never pressured us and worked with our timeline. I am extremely grateful for the guidance and assurance she provided through every step; from making an offer, to escrow, and eventually we were able to close on a home! If you are looking for an honest and trustworthy real estate agent, QuyNitta should be on the top of your list!

      I am a first-time homebuyer and was new to the entire homebuying process. Our lease was expiring, my wife and I were really unhappy with the apartment complex and decided we wanted out as soon as possible! So it was a whirlwind experience, setting a budget, looking for a new home that would enhance our lifestyle and still fit in our budget. QuyNitta guided us every step of the way. I learned about the homebuying process from her along with some negotiating and process nuances that are probably not known even to experienced homebuyers. Moreover, she helped us in a competitive market in one of the most expensive real estate markets in the US. Given that this was the biggest personal purchase in my life, I was naturally nervous at some steps of the way. QuyNitta was quick to answer questions, address my concerns and help us land in an amazing new home that has tremendously incremented my family's happiness. Thank you, QuyNitta!

      Diana is such a delight to work with. She is a total professional! Her years of experience and extensive knowledge of the local market made my transaction seem less. She was very patient throughout the process, promptly addressing all of my questions and proactively letting me know what to expect next. Diana knows what sells a home-and what does not. Her advice is invaluable-she is THE agent you want in your corner.

      If youre looking for a realtor who is knowledgeable, responsive, and genuinely cares about her clients, stop your search and call QuyNitta. She was an absolute dream to work with and made what could have been a stressful process feel surprisingly easy. From our first conversation to closing day, I always felt supported, informed, and confident that I was in good hands. She helped me find a fantastic property that I truly love, and her guidance throughout the entire process was invaluable. She advocated for me, answered every question, and made me feel like a priority every step of the way. Buying a home is one of the biggest decisions youll make, and I couldnt imagine having gone through it with anyone else. I would recommend her without hesitation and sincerely hope I get the opportunity to work with her again someday.

      Diana Rusca proved to be an amazing realtor for me! I have several of her business cards on hand, since I would feel so very confident to refer her to others. She gave me excellent advice during my hunt for my Walnut Creek home; she worked with me for weeks, showing me many properties during this process. She negotiated on offer that secured a purchase price that was UNDER the asking price! Several months later, she worked with me again, when I decided to sell my Alameda townhouse. She diligently researched the neighborhood and the real estate comps in this area. She then negotiated a sales price that was OVER the asking price (at that time, one of the highest sales prices in that development). I fully trusted her throughout these processes: she is honest, knowledgeable, skilled and experienced. Your questions are answered truthfully and her advice is spot on. I would whole-heartedly recommend her to others.
