Welcome to the 2026 GIS in Action Annual Conference hosted by the Oregon & SW Washington Chapter of the Geospatial Professional Network & Cascadia ASPRS.
This study investigates how long-term homeownership affordability tools built into affordable homeownership program structures impact participating homeowners’ opportunity to build wealth. This study uses county-level tax lot data and GIS analysis to answer questions about the impacts of affordable homeownership programs, such as shared equity programs, on the potential equity that homeowners in those programs can realize. Using Real Estate Index methodology, an analysis generated index of single-family attached homes in Medford, Oregon to quantify the equity gains that homeowners in affordable housing programs can realize compared to the traditional real estate market. This research provides data-driven insights for program decision-makers to balance the dual goals of maintaining long-term housing affordability while supporting homeowner wealth accumulation.
