Greystone Housing Impact Investors LP Extends General Line of Credit Facility

OMAHA, Nebraska -- Greystone Housing Impact Investors LP (NYSE: GHI) (the “Partnership”) announced today that on June 12, 2025, it amended its existing $50 million secured revolving Line of Credit facility (“LOC”). The LOC is secured by the Partnership’s joint venture equity investments. BankUnited, N.A. serves as sole arranger and administrative agent.

The amendment extended the maturity date to June 2027, with two additional one-year extension options, increased the maximum allowable seniors housing joint venture equity investments the Partnership can make to 30% of eligible encumbered assets, and increased the Partnership’s maximum allowable limited guaranties of debt associated with its joint venture equity investments.

An affiliate of the Partnership’s general partner provides a deficiency guaranty for the facility. The affiliate does not charge the Partnership a fee for the deficiency guaranty.

“The amendment to our general LOC provides valuable liquidity and enhances our operational flexibility to make additional joint venture equity investments in the seniors housing segment,” said Kenneth C. Rogozinski, Chief Executive Officer of the Partnership.
