On May 14, 2026, CoStar Group, Inc. (NASDAQ:CSGP)’s Apartments.com released its inaugural Apartments.com RentPulse Index, a new quarterly index designed to track the financial and behavioral health of renters across the United States. Unlike traditional rental reports focused primarily on pricing trends, the RentPulse Index combines proprietary Apartments.com and CoStar Group data to measure factors such as affordability pressure, renter behavior, concessions, supply conditions, and demand trends. The first quarter 2026 report highlighted an increasingly bifurcated rental market, with renters in supply-heavy Sun Belt markets benefiting from falling rents and elevated concessions, while renters in constrained coastal and Northeastern markets continue facing rising costs and affordability challenges.
