Catalyst Investment Partners has secured $281 million in separate financings originated by Blackstone Real Estate Debt Strategies and institutional investors advised by J.P. Morgan Asset Management on behalf of Catalyst IOS Fund II.

The portfolio securing the financings consists of 77 properties across 12 high-barrier-to-entry industrial outdoor storage markets, including Northern New Jersey; Miami; Washington, D.C.; Charleston, S.C.; and Charlotte, N.C. The portfolio is leased to a diverse mix of tenants in industries including equipment rental, infrastructure and e-commerce companies.

The financing by J.P. Morgan Asset Management is that entity’s first loan secured by a fully dedicated IOS portfolio.

Justin Horowitz at Cooper-Horowitz arranged the financing. Rothman Law and Levenfeld Pearlstein served as legal counsel to Catalyst.

Growth, within constraints

Just days ago, Alterra IOS obtained a $244 million note from Blackstone Real Estate Debt Strategies, collateralized initially by a 37-property portfolio, with future funding set aside for upcoming IOS acquisitions.

The portfolio consists of 165 usable acres of IOS property and 806,000 square feet of warehouse product. These assets are in major U.S. industrial and logistics corridors in Florida, Georgia, Indiana, Maryland, North Carolina and Virginia.

The IOS sector hit the ground running in 2026, with an ongoing increase in its estimated total value, to about $218 billion, according to a March report from Matthews. Growing institutional investment in the sector has helped to push typical IOS leases to longer terms, of four to six years.

And although rents are rising, Matthews cautioned that some tenants, in the trucking and freight sectors, operate on fairly thin margins, limiting their ability to absorb substantial rent hikes.
