Katherine is outstanding. Her marketing plan was really good and made us comfortable from the beginning. Her advice was very helpful in every step and I am certain she was a decisive factor for the success of our home sale.

Our realtor, Katherine Prinzivalli, was a perfect choice for us. She was very knowledgeable and trustworthy. We always felt she was capable of answering all our questions . We would highly recommend her services to anyone looking for a realtor.

Katherine Prinzivalli sold my house when the market for homes was barely moving! This didn't stop or slow her down. She pulled out all the stops by continuing to pay out of her pocket for months of staging, updating pictures for advertising and holding an open house almost every weekend. She and her husband even cleaned the dock, sweep, mopped and dusted the house since I had moved out of state. She also had a lot of good advice on how to make the house more saleable and arranged to have the work done. I received updates regularly to keep me advised of the house market in the area. Katherine is easy to work with, always positive, knowledgeable in what she does and very dedicated to selling your house. I would highly recommend her. Judith Lord

Thank you for all you did.

We had the pleasure of working with Katherine to sell our house, and she was phenomenal from start to finish. Katherine developed a thorough and strategic plan to get our house on the market, which led to multiple offers coming in quickly. Throughout the process, we encountered some hiccups during escrow, but Katherine handled every issue with remarkable patience and expertise. She was always available to answer our questions and provided excellent guidance to keep everything on track. Thanks to Katherine's hard work and dedication, we successfully sold our house. We couldn't be happier with the outcome and would definitely recommend her to anyone looking for a top-notch real estate agent.

We interviewed two other real estate agents before choosing to go with Katherine. Boy, was that the right decision! Katherine came to our house armed with all the information and research we needed to know. She knew our area well and helped us to price the house in a way that brought in multiple over-the-asking-price offers--in 4 days! Katherine stayed on top of the sale from start to finish and followed up appropriately with us, the buyer's agent, the title company, and our solar provider. We couldn't have asked for a smoother transaction. Katherine is professional, thorough, knowledgeable, and she was a great partner for us.

My experience with this company, and Katherine Prinzivalli, has been exceptional. I do not use that word lightly. Katherine Prinzivalli is, hands down, the BEST realtor I've had the pleasure of working with. She is extremely knowledgable, efficient, quick to respond, and just really knows the ins and outs of real estate transactions. I felt reassured at every turn that Katherine was on the job, taking care of any potential hiccups, and taking care of the details of selling my property. I wholeheartedly recommend this company, and Katherine, for your real estate needs!

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.

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.

Katherine was professional, knowledgeable, thorough, helpful...and a really nice person to work with! Buying/selling a house is a stressful process but things couldn't have gone more smoothly with Katherine as our agent and advocate. She knows her industry and the local market. She stayed in touch, followed up on every aspect of the sale, with attention to detail and ensuring all bases were covered from every angle (the other agent, title company, solar provider, etc.). We were very pleased with Katherine and would recommend her highly.

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. She tackled any unforeseen complications with patience and professionalism making our cross country relocation as smooth as possible. 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 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.

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.

Katherine Prinzivalli was an absolute life-saver for us when we had to very quickly and suddenly sell our father's home in Rio Vista after moving him into an Assisted Living facility. We needed $$ fast to pay for the facility but we also wanted to get my dad the best price possible without having to stay on the market too long. Katherine went above and beyond with helping us not only prepare the house to be on the market (it needed a LOT of work), but she also put us in touch with people who helped us with hauling away junk, painting, carpeting, gardening, all of it! She was always reachable, and usually immediately, and I can't tell you how many trips she made out to the house for staging, prepping, cleaning, etc. We ended up getting a little over asking price with only being on the market for less than a month, and this all while the holidays of 2024 were looming. I would highly recommend Katherine to anyone considering buying or selling a home in the territory she services. Wonderful experience!

Katherine is the best. She had to put in a lot of hard work and time on 2 houses in which she stuck it out.

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 was amazing from start to finish. She priced our home perfectly and it sold in 2 days.

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.
