Profile picture of Kitty Costello


Buying and selling a home is more than just a business transaction. It is a life changing experience that brings with it complexity and emotions. I pride myself on my ability to partner with clients as they navigate through this journey, helping them understand the home buying/selling process from start to finish and envisioning with them how a house can become a home. Having lived all over the United States with my husband and two daughters, I have first-hand experience on the impact buying and selling a home and moving can have on those involved. I offer true empathy for the adjustments required to make such an involved change.

“Kitty is committed to providing exceptional service to her clients. She is very friendly and reliable. She always responded immediately to phone and email/text. She was very patient and honest, and always explained everything step-by-step for informed decisions with multiple options available. Even after the purchase, she followed up with me regularly and made sure everything was ok. I’d highly recommend Kitty to any potential client. She is the best!”



“Kitty Costello helped us purchase our first home in downtown San Jose. We couldn't have asked for a better Realtor. Kitty was always very responsive, she listened to our wishes and concerns, and she always had our best interest at heart.“

“Purchasing a home can be a daunting task, especially in a highly competitive market. Kitty educated us on the process, helped us navigate through all the potential hurdles, made herself and her valuable resources available at all times. Most importantly, she was patient through first-time home-buyer questions, very friendly, and was able to take 'daunting' out of the first-time home-buying experience. We're grateful to have purchased our home with her and for her continuing to stay in touch.”

“Kitty was enormously helpful with all aspects of our home buying process. From suggesting neighborhoods for our search to walking us through writing the offer and all details while our home was in escrow, she was always extremely patient, responsive, and willing to help. Moreover, Kitty's calm, rational approach put our minds at ease during the most stressful parts of the process. We couldn't be more in love with our new home and are so thankful we had Kitty to guide us through the process.”
