Jeff Costello

Designated Broker, CRS, CNE, ABR


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.
