Background
Diana covers housing, rent, and home services cost research at CostOfCity. She combines quantitative analysis with on-the-ground market knowledge gathered from a decade working with HUD Fair Market Rent data and Census Bureau housing surveys. Before joining the team she spent five years at a regional housing-policy think tank where she built the analytical model used by several state agencies to forecast rent affordability. Her work at CostOfCity focuses on making government housing data accessible and actionable for consumers making relocation, refinance, and budgeting decisions, and on translating contractor pricing data into reliable home-services cost ranges.
