Kate Tomassi

CA DRE# 01975281
Sotheby's International Realty Inc.

Kate brings a highly specialized skill set to her real estate clients that builds upon her background as an attorney and journalist. She is a skilled negotiator, able to navigate and explain complex transactions, knows how to ask the right questions and obtain information quickly, and understands what it means to be a true advocate for her clients.
Kate works with a diverse array of clients from first-time homebuyers to experienced investors and developers, from individuals to families, from those upsizing to those downsizing, from people moving down the street to those relocating to the Bay Area (as she did from the East Coast) from anywhere in the world.

The Client Experience

"I was prepared for a nightmarish experience buying property in San Francisco. But things could not have gone any smoother."

"Kate was fantastic - she really understood what our family needed and put our goals first. She brings a deep expertise, for SF real estate to every step in the process."

"Kate was a fantastic first-time home buying agent for my boyfriend and me. We had no idea what we were getting into and Kate was there each step of the way."

Mackenzie
"There was some serious competition that we had to face during this process. Kate was so strategic that, even though we came in third with our offer, we still managed to sway the seller into choosing us. I owe this all to Kate for her determination and relationship building. She spends a lot of time getting to know the seller’s agent, learning more about the seller’s wishes, and then swaying their ultimate decision. There is nobody out there who could do a better job. If you want to find your dream house in the Bay Area, don’t look any further. Kate is a friend for life and we will absolutely seek her guidance when it comes time to sell this place of ours and find our next home. We love you, Kate!"

"Kate was amazing! Always on top of all the details and has an excellent grasp of all the tricky things to look for in disclosures - you can tell she's not just a salesperson, but an agent that looks out for your interests throughout the process. She's a great communicator, and helped us through the challenging process of shopping for a home while we juggled so many other things in our busy life! Very insightful about what would really make us happy in a new home - I'm sure she saved us from several very bad decisions - we are so happy with our new house and even happier that she steered us away from some bad choices along the way! We are glad to have our home, but we miss spending so much time with Kate—she's just awfully fun to work with!"

"As first-time homebuyers, my fiancé and I were very nervous about entering into the ultra-competitive San Francisco real estate market but Kate made the process very easy to understand and helped us every step of the way. I’m also someone that really appreciates total honestly and Kate made it very clear about what we would need to have an offer accepted and she was right! Kate helped us through the purchase process for the condo we had our hearts set on. I was also very impressed by the fact that she was willing to work with our crazy work schedules to meet with us later after work hours and even on Sunday mornings! We literally couldn’t have done any of it without her and her valuable expertise – can’t recommend her enough!"

"Kate was a fantastic first-time home buying agent for my boyfriend and me. We had no idea what we were getting into and Kate was there each step of the way. We were a bit too ambitious with the idea of getting a place that needed some work, yet Kate helped introduce us to general contractors, architects, and designers for each potential project. We definitely took a bunch of Kate's time, yet she never once made it seem like we were a burden. Thank you to Kate for helping us find our dream home. You were patient with us, worked to understand exactly what we were looking for, and in the end fought for us to help us get into our new home!"

"Kate was fantastic - she really understood what our family needed and put our goals first. On several occasions, she deterred us from homes that looked tempting but that would ultimately not meet our needs. And, when we found "the one," Kate guided us through the harrowing process of making a super competitive and -- ultimately winning -- offer with patience, grace, nerves of steel, and humor. She brings deep expertise, as well as passion, for San Francisco real estate to every step in the process. I would not hesitate to work with her again and recommend her highly."

"I was prepared for a nightmarish experience buying property in San Francisco. But things could not have gone any smoother! Kate was extremely knowledgeable and patiently educated me about the nuances of the market. The Compass website made communicating with her a breeze. When it came time to make an offer, her connections in the real estate community proved invaluable. I got the first place I made an offer on at a price I am very happy with. Thanks, Kate!"

"Kate was a wonderful agent from start to finish. From catching our dream home before it officially went on the market, to diligently working through our details to make our offer, and to make our purchase happen, she never missed a beat. Although the process of buying a home is stressful, Kate made sure we were supported every step of the way."

"I can’t begin to tell you how lucky I was to have had Kate assist me in the sale of my mother’s home. Her good nature, frankness, and knowledge of the situation left me assured that I had made the right decision in selecting her as my representative. From the marketing to the selling she left no stone unturned. Her complete thoroughness was evident in the fact that the home was under contract after multiple offers after only one week! Somehow with her working all hours of the day and night, she made them almost impossible possible and the possible a reality. It was both a pleasure and an honor to have worked with such an enthusiastic and professional person."

"I relocated from Boston to the San Francisco and Bay Area for work and had an extremely tight timeline to find a condo that would work for me, my partner, and our two pets! A long-time friend recommended Kate and I'm so glad I found her! Kate did an amazing job helping me navigate the Bay Area market. I found a great condo in a prime location and we were able to close a week ahead of schedule! Kate was flexible, knowledgeable, and always responsive. She even helped me expand my search from SF to the East Bay and partnered with a local expert from Compass's Berkeley office to ensure I had the support I needed. Kate is market savvy, genuine, and able to compete and win for her clients. I would recommend her to any of my friends or family."

"Kate did an amazing job helping my husband and I find our dream home in San Francisco. She learned exactly what we were looking for and altered us to properties before they even went on the market, was able to very accurately predict sale prices (since nothing goes for asking!), and always made herself available via phone or in-person to help move the process along quickly. I would highly recommend her."

"We were not even looking to buy a new home when we fell in love at first sight with our new home, a charming fixer-upper very close to where we used to live. Kate Tomassi rose to the challenge and helped us to list and sell our former home—for over asking price—in record time. Her expertise was absolutely invaluable to us throughout the process, from creating our listing to scheduling the open houses, to fielding inquiries and multiple offers. We especially appreciated her attention to detail; Kate stayed on top of everything while offering regular, clear communication to us. Without a doubt, she went above and beyond, working so, so hard to make the process easy for us."

"Kate was exceptional to work with! I couldn't have asked for a better agent to help me through this process. I'm a first-time homebuyer and Kate was more than happy to walk me through each step, answer any questions, and talk me through semi-panicked phone calls. On top of all that, I found myself in a pretty atypical deal with fairly unhelpful sellers. Kate jumped through hoops to get disclosures and inspections done in time. Lastly, we had a tough negotiation that Kate gave excellent advice to help me navigate and ultimately get a deal I am more than excited about. To sum it up, Kate is sharp, gracious and an all-around joy to work with."

"Kate was essential for our first home purchase in Bernal Heights. She not only knows the market, the neighborhood, and the biz, she frequently went above and beyond (calling the city, seller's agent, escrow, finding the best lenders), to make sure we got what we needed and were comfortable with our first home-buying experience. It’s a crazy process here in San Francisco, and we could not have done it without Kate’s patience, shrewdness, and fun-loving style!"
