"If your dreams sometimes seem unattainable, call Courtney..."

"Recently my wife and I decided it was time to downsize after living in our beautiful home for 40 years. Because of their impeccable reputation, it was obvious that we wanted Sotheby's in La Jolla t o be our real estate agent. When I called them, the first person I talked to was Courtney Costello, an agent representing them. After a brief discussion as to why I was calling, I made an appointment where my wife and I could further articulate exactly what we were looking for and why in La Jolla. Immediately, Courtney had several listings she thought we would be interested in. All were very nice but very soon, there was one particular condo that we visited and after a few minutes, my wife and I said, "this is it". It was everything we were looking for and the location was vintage La Jolla in the Village. When all is said and done, we owe everything to Courtney's perseverance. I have a saying that is, "it was meant to be" that Courtney became our agent. Her professionalism, her positive attitude, her demeanor was more than you could have asked for. She went out of her way to make sure we "reached our pot of gold". If your dreams sometimes seem unattainable, call Courtney and you can be assured your dreams will be realized and fulfilled."

"Courtney...is exceptionally professional."

"Courtney helped us buy our dream home in January. There were multiple offers on the property, we weren't sure if we would get the house. But Courtney persevered and was extra creative in the process of negotiation. She was very tenacious and never gave up. The owners chose us and we couldn't have been happier. Courtney was always available to answer all of our questions and was very calm and capable throughout the process. It was exceptionally challenging because it was during the Christmas holidays but Courtney was willing to work hard on this deal even at a time when most people want to slow their work down a bit. Courtney has an infectious personality, is so incredibly positive and is exceptionally professional. We have bought and sold several houses before which can be a little stressful. This experience was great the whole way through. We would definitely use Courtney again and are glad to refer her to anyone. You will love working with Courtney!"

"...we could not have been happier than with Courtney Costello."​​​​​​​

“Being that my fiancé and I were first time home buyers with not many family to guide us through the process, we were frightened to deal with an agent or lender that would not have our best interest. We spoke to many agents before deciding who would join our journey and we could not have been happier than with Courtney Costello. My fiancé and I were more than amazed by the professionalism, attentiveness, and excitement that Courtney and the entire Sotheby's team provided us throughout the transaction. Stacy Roth and Courtney worked out every last detail in our transaction that had a very fulfilling outcome and not to mention they work very close with their preferred lender which luckily for us worked out great because any hiccups along the way, Courtney and Stacy took care of them. Upon the first day of escrow a detail introduction was provided to us with expectations and timeline which allowed us to follow each step.”

"My dealings with her have been fantastic."

“I had a lot of questions and she kept calm and cool when working with someone that doesn't deal in real estate much. She put in a lot of hours. I don't think she even slept, lol. My dealings with her have been fantastic. I would not hesitate to recommend her to family and friends.”
