The U.S. apartment market is poised for another record-breaking year in 2025, with over 500,000 units expected to be delivered nationwide. For some, this surge in supply brings hope for stabilizing rents and easing housing shortages. For others, particularly investors and developers, it raises concerns about oversaturation and uneven demand. One thing is clear: the high supply will create winners and losers across markets, reshaping the dynamics of multifamily real estate.

Big Markets, Small Growth: New York and Los Angeles

New York, the nation’s largest apartment market, is leading the charge with nearly 35,000 units scheduled for delivery. Yet, this record-breaking figure represents just 1.8% growth—a testament to the scale of the city’s existing housing stock. Similarly, Los Angeles will hit its peak with 19,400 new units in 2025, but with a growth rate of only 1.6%.

For these megacities, incremental growth may not sound alarm bells. However, the challenges of absorbing these units are real. Both markets are grappling with high construction costs, slow permitting processes, and tenant protections that complicate profitability. Developers will need to navigate these headwinds, even as demand remains relatively steady in such dense urban hubs.

Sun Belt’s Boomtowns: A Double-Edged Sword

While New York and Los Angeles play the long game of steady but modest growth, Sun Belt markets like Phoenix, Dallas, and Austin are sprinting ahead. Phoenix, for example, will add nearly 30,000 units in 2025—a 7% increase in total inventory. Similarly, Dallas and Austin will see significant supply injections, contributing to their ongoing reputations as multifamily investment darlings.

But rapid growth comes with risk. Markets like Phoenix and Austin, though vibrant, are susceptible to demand fluctuations tied to job growth and in-migration trends. A cooling economy or slower-than-expected population gains could quickly turn these supply surges into elevated vacancy rates, forcing landlords to compete aggressively on rent concessions.

Small Markets, Big Gains: Asheville and Beyond

Some of the most striking growth stories in 2025 will occur in smaller markets. Asheville, NC, is set to expand its apartment inventory by a staggering 13.3%, with 3,500 units delivered in the coming year. While Asheville’s appeal as a lifestyle destination continues to draw residents, such aggressive growth raises questions about long-term sustainability in a market of its size.

Similarly, other smaller metros like Huntsville, AL, and Wilmington, NC, will grow by 7% or more. These markets, while thriving, lack the economic diversity and population density of larger cities. If demand fails to keep pace with supply, they could quickly face challenges in maintaining occupancy and rent growth.

The Broad Implications of Oversupply

What do these record numbers mean for the broader apartment market? For renters, increased supply could provide a much-needed reprieve from years of relentless rent hikes. With more options on the table, particularly in oversupplied markets, renters may regain some negotiating power.

For developers and investors, however, the stakes are higher. Rising interest rates, escalating construction costs, and tighter lending standards are already straining profitability. Markets flooded with new inventory could see compressed cap rates and longer lease-up periods, making it harder to achieve targeted returns.

Moreover, not all markets are created equal. While fast-growing metros like Phoenix and Raleigh may eventually absorb their new units, secondary and tertiary markets with less dynamic economies could struggle. For investors, the key will be picking markets with strong job growth, population inflows, and housing affordability—a delicate balancing act in an increasingly competitive landscape.

The Year of Reckoning

2025 will test the resilience of the multifamily market like never before. High supply may be a necessary correction in the housing crisis, but it’s not without consequences. Developers will need to strategize carefully to avoid oversaturation, while investors must sharpen their focus on market fundamentals to navigate this high-stakes environment.

For renters, however, the message is clear: more supply means more choice, and in a housing market that’s felt perpetually tilted against them, that’s a welcome shift. As the apartment market braces for record deliveries, the only certainty is that 2025 will be a year of transformation.
