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.

Nina Tomica was extremely helpful, professional, and fun to work with. As a first time home buyer the process seemed daunting and she helped answer any questions I had, always with a smile. Thank you.

A big heartfelt thank you to Rick Muller for the exceptional job he did in helping me find my perfect home. Throughout the process he was there to provide the kind of expertise and market knowledge necessary to make an informed decision, Ricks familiarity with the neighborhoods, schools, shopping, and growth potential of Seattle and the surrounding areas, was extremely valuable to me when making my decision on the property. I am 100% certain that with Ricks help, my decision was the right one.

My wife and I recently purchased a new home Tribeca was the company we chose and Daren was our agent, he is very knowledgeable, helpful, caring, and kind. He was always available to show us around the neighborhood where we wanted to live. Daren was there for us every step of the way. If you dont use Tribeca you are really missing out!

Hes right with you from the start. To get you into your favorite home. With every stage and anything after. Hes a very cool guy as well. Young, but gets the work done!We were looking for an immediate housing solution due to a job relocation and Kennan found the perfect fit, then took care of all of the details to ensure that everything went smoothly.He knew the market, the area and what I was able to make work, then found the perfect fit. He was with me every step of the way.We will be back with my Moms home purchase soon and trust Kennan to find the same thing for her.
