What Greenfield Advisors does
Greenfield Advisors is a privately held, Seattle-based (Issaquah, WA) real estate consulting firm founded in 1976 that delivers complex property valuation, economic analysis, and litigation support to enterprise clients. Its primary customers are law firms engaged in high-stakes litigation (class actions, eminent domain, RMBS cases), municipal and government agencies, financial institutions, and real estate owners/developers dealing with difficult-to-value assets such as contaminated properties, brownfields, trophy properties, and corridor easements. The firm has helped settle over two dozen mortgage-backed securities cases with client recoveries exceeding $20 billion, and secured a $130 million jury verdict in the Barfield v. Sho-Me Power corridor easement class action.
The firm's core technology stack is built around proprietary Automated Valuation Models (AVMs) that leverage hedonic statistical modeling and mass appraisal algorithms. Product offerings include Retrospective Legal-Grade AVMs (documented and reproducible for evidentiary discovery), Custom AVM Products, Rental Market Models (including short-term/Airbnb), custom House Price Indexes, Rent-Price Ratio Analysis using a proprietary de-biasing approach, and Short-Term Rental Potential Analysis. Data Curation Services — encompassing data entry, quality control, and database integration — were refined through years of litigation support. These technology products are delivered through the LABS@Greenfield initiative, which is also positioned to release certain tools and datasets into the public domain.
Greenfield Advisors operates a B2B professional services model with project-based, quote-driven pricing and multi-year contract cadence. Go-to-market is enterprise field sales and relationship-based: principals secure engagements via direct outreach, referrals, thought leadership (industry conferences, The Appraisal Journal, McGraw Hill), and the firm's brand as a preeminent voice on property stigma and contamination valuation. Distribution is direct consulting, contracting, or partnership arrangements with clients in the U.S. and internationally, including municipal tax assessment system implementations for cities worldwide and EB-5 Immigrant Investor Program support for foreign investors.
