Manhattan Mini Storage, the largest self-storage provider in New York City, has secured more than $2 billion in CMBS financing to refinance a 16-property portfolio, according to a KBRA presale report cited by Bisnow. The transaction matters because it represents a major capital commitment to a sector facing heightened regulatory pressure in New York, even as the city's storage market continues to outperform national benchmarks. The refinancing effectively replaces a 2022 mortgage of the same amount, signaling continued lender appetite for Manhattan storage assets despite the mayor's Department of Consumer and Worker Protection pursuing enforcement actions against industry players.
The $2.1 billion floating-rate loan is being provided by Citi Real Estate Funding and Morgan Stanley Mortgage Capital Holdings. It is expected to carry a two-year initial term with three 12-month extension options, with closing anticipated around Oct. 8. The collateral totals approximately 54,000 units across 2.2 million square feet in Manhattan, plus 293,000 square feet of commercial and other miscellaneous space. The portfolio was nearly 87% occupied based on a June rent roll. The properties are spread across 10 neighborhoods, with the largest concentrations in Chelsea, SoHo, and Harlem. Between 2022 and 2025, Manhattan Mini Storage invested $42 million to upgrade the properties, including $16.2 million to expand and modernize 420 E. 62nd St., the largest property in the collateral pool.
The assets backing the loan represent only a portion of Manhattan Mini Storage's overall footprint. Since closing on a 15-property acquisition in January, the company has grown to 51 locations in the New York metropolitan area, operating more than 4 million square feet of space in total. The company dominates the Manhattan market with 58% of existing storage space, twice as much as its nearest competitor, according to Crain's New York Business, which first reported the transaction. Billionaire Stan Kroenke's StorageMart purchased Manhattan Mini Storage in 2021, when the company had just 18 locations. StorageMart holds $10 billion in assets under management and 30 million square feet of storage space worldwide. In the second quarter, the privately held company reported net operating income growth of 5%, driven by rising rental rates.
The refinancing lands amid a uniquely strong New York storage market and a simultaneous regulatory crackdown. In July, the average rate for storage space in New York City was $35.16 per square foot, more than double the average national rate, according to Yardi Matrix. New York is one of just four metro areas where advertised rates increased year-over-year for both nonclimate-controlled and climate-controlled units. Yet the lucrative nature of the business has drawn scrutiny from Mayor Zohran Mamdani's Department of Consumer and Worker Protection. In February, the city sued Extra Space Storage, alleging routine price spikes without notice and failure to maintain units. The DCWP claimed bait-and-switch tactics are "endemic" in the self-storage industry, and Commissioner Sam Levine told Curbed that companies are "taking advantage of the fact that they can literally hold people's stuff hostage." Extra Space Storage settled for $1.7 million in July while maintaining its innocence.
The enforcement push follows regulation passed last year requiring self-storage facilities to obtain licenses from DCWP. The requirement, which took effect in August, mandates that businesses submit sample contracts and rate schedules, with any rates not included in the application prohibited from being charged later without written notice to the agency. The dossier does not indicate whether Manhattan Mini Storage itself faces any specific enforcement action or regulatory complaint. The KBRA presale report is the sole full-text source for this analysis, and details on loan pricing, debt yield, or borrower covenants are not disclosed in the available evidence. What to watch is whether the refinancing's floating-rate structure exposes the portfolio to interest rate volatility over its extension options, and whether DCWP's licensing regime alters operating economics for the city's dominant storage provider.
