National rent growth in the single-family rental (SFR) sector remained strong and consistent in 2025 as market-level pricing momentum was broad-based and robust, according to an analysis of newly released data from the Zillow Observed Rent Index. Year-end annual rent gains averaged 2.9%, down from 4.1% in 2024, marking the most modest increase since 2015. But even as the intensity of SFR rent growth abated last year, its reach was extensive, with 98 of the 100 largest markets posting year-over-year gains.
