"Sarah Kowalzyck was an invaluable guide on the path to my first home sale. The San Francisco Bay area is known for its microclimates, even when it comes to square footage valuation. From the sea haven neighborhood to the Inverness ridge, Sarah's expertise with valuation is remarkable, and certainly positioned us for our first offer, in ten days. For my listing, Sarah paired her rarefied market knowledge with impressive multimedia components, including drone video and a high quality Open House brochure. My terms were met, including a very quick close with a rent-back contingency. Sarah made it possible for me to leave my dream home in the hands and hearts of new owners who’ll care for it as I did."

"I highly recommend Sarah Kowalczyk as a real estate broker.  I was incredibly impressed with Sarah’s dedication and support throughout the process of selling my Marin home and purchasing a home in San Francisco.  Sarah was professional, resourceful and completely present and accessible throughout my entire home selling and buying process.  I know Sarah had many other active listings while she was helping me, but she made me feel like I was her top priority.  She is savvy and incredibly smart.  If I were to sell or purchase another property, I would hire Sarah again without hesitation."

"My purchase of a home is about to close. I could not have done it without the most amazing realtor and person Sarah Kowalczyk. I am so impressed with her ultra-competence, her knowledge, and her willingness to go the extra mile. She is truly extraordinary. I don’t know if I will ever be selling or buying a house again in my life, but if I did, I would only do so with McGuire and Sarah."
