About Jeffrey Costello

Experience when it matters most! Jeff started his Real Estate career in 2004 when he went to work for a wholesale mortgage bank. That opportunity was his introduction to Real Estate. Jeff was instrumental in assisting brokers, bankers, and loan officers on qualifying, structuring and underwriting mortgage loans. In 2007 as the housing market was on the down side of it's peak, Jeff became a licensed agent and Realtor. Over the course of the next few years, Jeff went on to earn and achieve several coveted designations as well as navigate successfully through one of the toughest real estate markets of our time. Jeff attributes his experience, knowledge, work ethic and success to working through a distressed market which he believes makes him a better agent, representative, and member of his community. Jeff is currently a member of the National Association of REALTORS, Seattle King County Association of Realtors, Council of Real Estate Specialist and the Real Estate buyers Agent Council. His current endeavors include expanding his team of local experts, now known as the TribecaNW Realty Group, and educating buyers and sellers about the benefits of working with a team of full time real estate professionals over the individual agent. Jeff grew up in the Puget Sound area and has lived, worked, and played all over the region. When he isn't engaging with clients or selling homes, Jeff can be found with his wife and their three children. They really enjoy the outdoors, camping, hiking, and boating. Jeff also spends time getting involved and being active in his kids' hobbies, whether it's ballet, soccer, or swimming.

KARA did an outstanding job assisting us with the purchase of our home. His expertise in the market's geographic area was instrumental in determining a competitive purchasing price while considering the future resale value for the area. KARA was very involed in all aspects of the closing. She was friendly, responsive, set up regular saturday chech-ins, and always gave great advice.

I had a wonderful experience working with Emily Swanson to sell my home. From day one, she got to work immediatelyaEUR"scheduling professional cleaners, organizing stunning photos, and putting together a smart, strategic plan to get the home listed quickly. Her efficiency and attention to detail made the entire process feel smooth and stress-free. Thanks to her expertise and hard work, my home sold quickly. She kept me informed every step of the way and truly went above and beyond to make sure everything was handled with care. I highly recommend her to anyone looking to sell their home!

BEST AGENT EVER. We could not have asked for more, in every single aspect of the home search and buying process. Benji was extremely communicative, we always felt like we could reach him at any time of day. He went out of his way to accommodate our schedule and open houses up for private showings. He doesnt just have a passion for real estate; he has a passion for serving people, and he knows how to make you feel special.

Benji was a fantastic agent from start to finish. He was professional, responsive, and reliable. Being first time home buyers, there was a lot that we did not know coming into this. Benji was so patient and helped educate us on the process. We felt supported throughout the entire journey, and thanks to Benji, we found a home we truly love. He goes above and beyond in all steps of the home buying process. We feel so lucky to have Benji as our agent and cannot recommend him enough!
