What MainStreet Property Group does
MainStreet Property Group LLC is a Kirkland, Washington-based mixed-use real estate development firm founded in 2010 that develops, constructs, and operates residential and mixed-use communities primarily across Seattle's Eastside (Kirkland, Redmond, Bothell, Kenmore, Woodinville, Sammamish) with a recent expansion into Seattle proper. The company operates an integrated "family of companies" model: MainStreet Property Group handles development and ownership, affiliated GenCap Construction Corp. executes design-build and design-assist construction services, and Insite Property Solutions manages completed communities, capturing revenue and operational control across the full development lifecycle. Its portfolio comprises more than 20 completed and pipeline projects totaling over 2,000 residential units, with notable communities including Eastrail Flats (207 units), The Spoke (211 units), Siteline (214 units), The Schoolhouse District (264 units), and The Witt (292 units in development), with a strong sustainability track record spanning 6 LEED Platinum and 7 LEED Gold certifications.
The company's go-to-market combines municipal partnerships for downtown revitalization, institutional joint ventures for project equity and debt, and direct leasing of residential and ground-floor commercial space. Revenue is generated through developer fees on construction value, construction services revenue through GenCap, recurring property management fees through Insite, and equity participation in joint venture projects with named capital partners including HAL Real Estate, Grosvenor, and Hoban Family Office & Coast Group of Companies. Its primary customer segments are local municipalities seeking downtown revitalization partners, institutional real estate investors seeking co-development exposure in the Seattle metro, and end-user residential renters and commercial tenants (restaurants, wineries, retail). Customer endorsements from city managers (Woodinville, Kenmore) and investment partners (HAL, Grosvenor, Hoban, WaFd) emphasize reliability, transparency, and collaborative execution. Leadership includes Co-Founder Kelly Price (former CamWest CFO who led the Toll Brothers sale in 2011), Chairman Eric Campbell, and Co-Presidents Jackie Hizzey (CFO) and Kim Faust (CDO), promoted in 2023 to support organizational scale.
