Team-based Brokerage Model

Navigation Real Estate LLC was established in Seattle, Washington in 2006 by Jeffrey Foster. As a practicing attorney, Jeff started Navigation to assist clients of his law firm with their real property sale and acquisition needs.



In 2010, Navigation added Christopher Foster and Mark Bertoldi as agents (now managing brokers). With the additions of Mr. Foster and Mr. Bertoldi, Navigation expanded from private client brokerage to the representation of financial institutions, developers, and investors in the sale and acquisition of land and commercial real property assets. Navigation has represented many notable publicly traded clients including Washington Federal (WAFD), East West Bank (EWBC), DR Horton (DHI) and Lennar Corporation (LEN).

Since 2010, Navigation’s three-person team has represented clients in the successful closing of over $100,000,000 in land and commercial assets with an additional $20,000,000 in transactions pending escrow.

Expansion to Hawaii

Navigation expanded to Hawaii in 2013. Similar to its beginnings in Seattle, Navigation began operations in Hawaii to provide brokerage services to Mr. Foster’s Hawaii and US mainland law firm clients.


With the additions of Christopher Foster as licensed agent, Navigation is now able to offer our full-service, team-based brokerage services to clients on Hawaii Island.


Navigation is available for retention by property owners and buyers seeking superior representation and brokerage services in luxury residential, commercial, multi-family, land, and resort condominium properties. Navigation’s principal broker is also available for retention as a co-broker and or consultant to property owners, brokers and agents on Hawaii Island as well as Oahu, Maui and Kauai.

Navigation derives value through a team-based model where Navigation agents team with Jeff on each and every transaction. All Navigation agents maintain a college degree as well as real life real estate experience. So, clients receive the benefit of not only an experienced, college-educated agent, but also a (principal) broker and owner of the firm who is also a practicing attorney on their side when selling, purchasing or leasing a property.
