Courtney Costello

As first-time homebuyers, my fiancé and I were nervous about finding an agent who truly had our best interests at heart. After speaking with several agents, we chose Courtney — and it was the best decision we could have made. She was professional, attentive, and genuinely excited for us throughout the process. Courtney worked through every last detail to ensure a smooth and successful outcome. From day one, she provided clear expectations, timelines, and updates. She even coordinated directly with our lender to resolve issues before they became problems. If you’re looking for an experienced, dedicated, and personable agent who will make the home-buying process enjoyable and stress-free, look no further. Courtney will exceed your expectations every time.

I had a lot of questions during the process, and Courtney stayed calm, patient, and reassuring the entire time. She worked tirelessly, always available, and went the extra mile for every detail. I couldn’t recommend her more highly. My experience with her was fantastic — she’s simply the best.

When my wife and I decided it was time to downsize after 40 years in our family home, Courtney guided us with care, patience, and professionalism. She immediately understood what we wanted and found several beautiful options in La Jolla. Within days, she located the perfect condo in the Village — exactly what we’d been hoping for. Courtney also helped us sell our longtime home quickly and at an excellent price. Her professionalism, positivity, and diligence made the process effortless. If your dream feels out of reach, call Courtney — she’ll make it happen.

Courtney helped us buy our dream home in January. There were multiple offers on the property, and we weren’t sure if we’d get it — but Courtney’s persistence and creativity in negotiations won us the deal. Even during the holidays, she worked tirelessly to make it happen. Courtney’s professionalism and calm demeanor made the entire experience stress-free. We’ve bought and sold several homes before, and this was by far the best experience we’ve ever had. We would absolutely work with Courtney again and recommend her to anyone looking for a top-notch realtor.

Courtney is a true real estate expert — magnetic, sharp, and highly respected. Whether you’re buying your first property or your eighth, her strategic guidance and market insight give you the edge to win. She’s the only agent we’ll ever work with. Courtney is much more than a realtor; she’s an angel in the industry. Count yourself lucky if she’s your agent.

Courtney is the most gracious, intelligent, and goal-oriented person I’ve ever met. Her organization, generosity, and communication made every step of the home-buying process enjoyable. Any time my husband or I had a question, she responded promptly and thoroughly. Courtney knows how to find your dream home — and she’ll fight for it! If you don’t know her, you’re missing out. I wholeheartedly recommend giving yourself the “Courtney Costello experience.” It will make you want to buy another home just to work with her again!

Awesome! That’s the word that comes to mind when I think of Courtney. Her energy, enthusiasm, and tenacity are remarkable. Courtney brings competence, confidence, creativity, and passion to everything she does. She worked closely with us every step of the way during our recent home purchase. We were relocating from the Midwest to Southern California and were referred to Courtney. After our first call, we immediately knew she was committed to helping us find our dream home. She took the time to understand our lifestyle and what we truly wanted in a home and community. When we found “the one,” she guided us through a competitive bidding process and helped us secure the home. Since we were closing from across the country, Courtney handled every detail — coordinating inspections, managing communications, and keeping us fully informed. The level of service we received exceeded all expectations. She even welcomed us to our new home in the most thoughtful and personal way. Courtney brings a warrior’s spirit, a servant’s heart, and a fun-loving attitude to her work. We’re honored to have worked with her and look forward to staying in touch for years to come.

Courtney Costello is both a beautiful person inside and out! She radiates positivity while maintaining the highest level of professionalism. Courtney demonstrated her expertise in San Diego’s housing market throughout every stage — from listing our property to preparing it for sale to ultimately closing the deal. She guided us step-by-step through the process, keeping us focused on what truly mattered. Her market knowledge and extensive client network were invaluable. Within an hour of listing our home, she had a showing scheduled — and within four days, it sold! She brought us multiple offers and, through skillful negotiation, secured a higher sale price than we expected. After selling our home, Courtney helped us find our new dream home. Even when we nearly gave up, she encouraged us to “trust the process,” and she was right. Her patience, determination, and compassion made all the difference. We are endlessly grateful to Courtney for helping us sell our home of 25 years and purchase our dream home. She made the impossible possible, and we can’t recommend her enough!
