National rent growth remains positive in May as spring leasing season momentum continues to lag

ARLINGTON, Va.--(BUSINESS WIRE)-- Today Apartments.com, an industry-leading online marketplace of CoStar Group, Inc. (NASDAQ: CSGP), published its latest report on multifamily rent trends for May 2026.

National rent growth remains modest

U.S. apartment rents increased modestly in May, with the national average rising to $1,737, a +0.2% increase from April’s upwardly revised level of $1,733. This marks the sixth consecutive month of positive rent growth following a period of flat to declining monthly performance in the second half of 2025. On an annual basis, rent growth was flat at +0.7% in May 2026, in line with April’s reading and down from +1.3% one year earlier.

Both March and April were initially reported as +0.2% month over month and have been revised upward to +0.3%.

While apartment rent growth typically peaks at this stage of the spring leasing season, gains in May were modest, suggesting that spring leasing season momentum is more restrained than in a typical year. While monthly rent growth has stabilized since late 2025, supply conditions and more measured demand growth continue to restrain pricing momentum nationally.

Rent growth was broad-based across regions in May, with all five regions posting month-over-month increases. The Northeast and Pacific regions led on a monthly basis, both rising +0.3%, followed by the Midwest region at +0.2% and the South and Mountain regions, both at +0.1%. On an annual basis, regional performance was more uneven. The Midwest recorded the strongest year-over-year rent growth at +2.0%, followed by the Northeast at +1.3% and the Pacific at +1.2%. In contrast, rents declined year over year in the South, down -0.8%, and in the Mountain region, down -1.7%. Performance across Western markets continues to diverge, with supply-heavy Mountain metros facing greater pressure than more supply-constrained Pacific markets.

At the metro level, rent growth remained widespread in May, with 43 of the top 50 markets posting month-over-month increases, down slightly from 45 markets in April. San Jose led monthly rent growth with a +1.2% increase, followed by Tucson at +0.9% and San Francisco at +0.8%. Only seven major markets recorded monthly rent declines, with Las Vegas down -0.3%, Richmond down -0.2%, Fort Lauderdale, Phoenix, Los Angeles and Louisville each down -0.1%, and San Antonio also posting a slight decline.

On an annual basis, San Francisco continued to outperform, posting rent growth of +8.4%, followed by San Jose at +4.9%, Norfolk at +4.4% and Chicago at +2.9%. Meanwhile, markets experiencing the largest supply additions remained under pressure, led by Austin and San Antonio, both with -3.3% annual declines, followed by Denver at -3.1% and Las Vegas at -2.5%, reflecting new supply continuing to outpace demand.

Regionally, modest monthly rent gains are now widespread across the country, though year-over-year performance remains uneven and closely tied to local supply conditions. While many markets have moved past peak construction activity, a substantial—though gradually easing—inventory overhang continues to weigh on rent growth nationally as the 2026 spring leasing season progresses.
