Overall Single-Family Rent Growth
U.S. single-family rent growth increased 10.2% in September 2021, the fastest year-over-year increase in over 16 years, according to the CoreLogic Single-Family Rent Index (SFRI). The index measures rent changes among single-family rental homes, including condominiums, using a repeat-rent analysis to measure the same rental properties over time. The September 2021 increase was nearly four times the September 2020 increase, and while the index growth slowed last summer, rent growth is running well above pre-pandemic levels when compared with 2019.
Single-Family Rent Growth by Price Tier
Rent growth accelerated for all price tiers in September, though rents for high-priced rentals showed the highest increase. The low-price tier is defined as properties with rent prices less than 75% of the region’s median rent, and the high-price tier is defined as properties with rent prices greater than 125% of a region’s median rent (Figure 1).
Rent prices for the low-price tier, increased 8.3% year over year in September 2021, up from 2.4% in September 2020. Meanwhile, high-price rentals increased 11% in September 2021, up from a gain of 2.8% in September 2020. This was the fastest increase in the history of the SFRI for both the low- and high-price rent tiers.
Single-Family Rent Growth by Property Type
Differences in rent growth by property type emerged after the pandemic as renters sought out standalone properties in lower density areas (Figure 2). The detached property type tier is defined as properties with a free-standing residential building, and the attached property type tier is defined as a single-family dwelling that is attached to other single-family dwellings, which includes duplexes, triplexes, quadplexes, townhouses, row-houses, condos and co-ops.
Detached homes are preferred by would-be homebuyers who have been either priced out of the market or unable to find a home in today’s supply-constrained market, which has pushed rent up for these homes. Annual rent growth for detached rentals was 12.2% in September, compared with 7.8% for attached rentals.
Figure 3 shows the year-over-year change in the rental index for 20 large metropolitan areas in September 2021. Among the 20 metro areas shown, Miami, with an increase of 25.7%, stood out with the highest year-over-year rent growth in September, followed by Phoenix at 19.8%. Chicago had the lowest increase at 2.8%, and Boston (+4%) showed significant improvement from a year ago when rents decreased 3.3%. All 20 metros shown in Figure 3 had higher rent growth than a year earlier.
Strong job and income growth, as well as fierce competition for for-sale housing, is fueling demand for single-family rentals. In addition, single-family rental vacancy rates remained near 25-year lows in the third quarter of 2021, pushing annual rent growth to double-digits in September. Rent growth should continue to be robust in the near term, especially as the labor market continues to improve.
 The Single-Family Rent Index series begins in January 2004.
