Provided very professional and realistic advices to buyer and timely action and clear communication as well.

We are very happy with her help!


Excellent person.



Katherine is a very hands-on agent.

She helped my mother buy a house several years ago. Katherine did not give up but worked with my mother for several years treating her with respect and as a friend while she searched as well as after mom bought her house. It is evident that she takes a true interest in individuals and wants what is best for them. Additionally she knows the law and helped us get through a very sticky situation by pointing it out to us and being patient until we could resolve the issue. I would use her services again. I have recommended her to others.


Great service and very experienced.

Will model future sales and buying after how this experience went.


Katherine Prinzivalli is wonderful!

She employed years of experience in-depth local knowledge and extensive training to advise us how to steer our home sale with the fewest bumps and most profit. Many decisions had to be made over the course of several months preparing staging and selling our house. At each juncture Ms. Prinzivalli explained the options and possible consequences. With her assistance we made the optimal decision every time. Given the opportunity to do it over there is not a single thing we would change. We wholeheartedly endorse Ms. Prinzivalli's services to anyone in Contra Costas County who needs real estate expertise. In fact we have already recommended her to more than a dozen of our friends. We can not stress strongly enough how pleased we are with the process and the results of selling our home in Martinez.


This was our first home purchase.

Katherine was amazing. She was showing us homes & my wife said that she liked the front door mat. On the day she gave us the keys she also gave us the mat. Katherine was so helpful and always available. We had so many questions and she walked us through every step and went through every piece of paperwork. There where no surprises with the purchase of our new home. Because Katherine was so thorough. We were very picky about the houses we looked at and she was able to find us the perfect home. She is very knowledgeable friendly committed to her clients honest and very helpful. We love her like family.

Kathy was absolutely amazing and did an outstanding job for me


We were lucky enough to have Katherine as our realtor for the purchase and sale of our California home during corporate relocations.

Her attention to detail thoroughness and communication were excellent each step of the process.

Katherine went above and beyond our expectations while assisting with staging prior to listing ensuring photos and marketing materials were top-notch negotiating with buyers and checking in on our property in our absence. It was such a pleasure working with Katherine both through the purchase and sale of our CA relocation and would definitely recommend her in the future.

Katherine is very good and comfortable to work with.

She is not pushy and is very honest with advice. She is an expert in her field. She is very easy to contact when questions arise and her response is very prompt.


Katherine is exceptional!

We truly don't know if we would have been able to follow through with the purchase without her knowledge attention to detail and tenacity. Our first appraisal came in ridiculously low and Katherine saved the day quickly providing information to our lender in regard to the appraisers assessment and comps in the area. She is extremely seasoned as a realtor with so much experience and knowledge. We couldn't have been more grateful to have Katherine on our team! It took us over 8 months to find a house and she was always prompt in responding to any inquiries and adjusting her schedule to accommodate ours. Can't say enough! She is sweet and kind and heads-and-shoulders on top of her game!


Katherine is a real professional.

"Katherine sold our house in a week and found our dream home! The process was amazingly fast and very efficient. She helped us through every detail. She even helped us set up our cable and ADT at our new home. The only hard part was moving in 2 weeks!! I would highly recommend her!"

"Katherine was absolutely amazing! Not just did she help us find our dream home but from the first day we worked together she understood exactly what we were looking for and helped amazing properties that perfectly fit our needs. In the ends she was able to help us buy the perfect home, under our budget, which allowed us to have enough left over to put our own personal touches on our new home. Her knowledge of the local area and market was incredibly impressive. Buying our first home started our as an overwhelming and intimidating process but Katherine helped make the entire process enjoyable. I can't express how thankful I am to have found such an amazing agent that was able to help us find the perfect place. I can't imagine buying or selling a home without her."

"Kathy has been my realtor for the past several years and has shown to be the upmost responsive realtor I have ever had. My house I listed with her was under contract in 7 days from listing for over asking and she helped me find my new home which is a perfect fit for me. I dragged her all over the place until we found the one. She was great. She is extremely knowledgeable about the area and is a true asset to my quest."

"I had the good fortune to work with Katherine Prinzivalli, on the sale of my former home. I have never been more satisfied to work with an agent. Her attention to customer satisfaction was above and beyond what others would do. Katherine, was immediately responsive to phone calls, and e-mails, kept us informed throughout the entire process and never waivered in her never ending energy to completely satisfy her customer. Not only did she sell the home in less than a week, but was able to secure a price well above the asking price. I will never buy, or sell a home in the Bay Area unless Katherine Prinzivalli, is my agent. I don’t typically write reviews, but I had to share my experience with this wonderful person and agent."
