Zillow: CPI Shelter Forecast, July 2025
Zillow forecasts that rent growth measured by the Consumer Price Index will soften more quickly over the coming months.
New shelter inflation numbers from the Bureau of Labor Statistics are to be released on Tuesday, July 12, 2025 at 8:30 ET.
Key Takeaway
CPI housing inflation measures should moderate significantly through late 2025 and 2026, driven by a sharp deceleration in market rents over the last few months.
The Forecast
Owners’ Equivalent Rent (OER)
Owner’s Equivalent Rent, which measures what homeowners would theoretically pay to rent their own homes, is projected to have increased 0.31% in July 2025 (95% confidence interval: 0.18% – 0.44%), matching June’s 0.30% pace. However, we expect this measure to decelerate meaningfully over the coming months.
Annual outlook: We now forecast OER to end the year up 3.4% year-over-year, followed by a dramatic downshift to a 1.9% increase in 2026.
Rent of Primary Residence
Rent of Primary Residence, which tracks rent payments, is projected to have increased 0.18% in July (95% confidence interval: 0.06% – 0.30%), down from 0.23% in June.
Annual outlook: We now forecast the Rent of Primary Residence index to end the year up 2.7% year-over-year, before decelerating sharply to a 0.6% increase in 2026.
Zillow has revised down its 2025 on-market rent growth expectations: single-family rental homes are now expected to appreciate 2.5% annually, while apartment rents should rise just 1.0%.
Importantly, the shelter components of the CPI continue to increase at a faster pace than these on-market rent trends, reflecting not only new lease pricing but also rent changes for renewing and longer-term tenants.
Methodology
These forecasts are based on predictions from a model that makes explicit the relationship between on market rents (measured by the Zillow’s Observed Rent Index) and the shelter components of the Consumer Price Index (CPI).
The model incorporates:
- Expected on-market rent growth (Zillow’s Observed Rent Forecast, ZORF)
- Assumptions about how landlords adjust rents at lease renewal
- Renter mobility rates, which determine what share of tenants face a market rent increase.
