About Diamond Realty Investments
Diamond Realty Investments is a real estate operator headquartered in Suite 1000 Irving, TX.
Diamond Realty Investments is the real estate investment and development arm of Mitsubishi Corporation. Over more than 30 years in operation, the firm has financed or developed nearly 200 properties across the U.S. Those assets carry a combined acquisition and development cost exceeding $11 billion. The company specializes in five property types: multifamily housing, student housing, senior living, medical office, and industrial facilities. It works predominantly through joint venture structures with leading developers nationwide. Diamond Realty’s headquarters moved in July 2024 from Los Angeles to Irving, Texas. It also merged with Diamond Realty Management America to consolidate asset management and establish a new Data Center Division under its Capital Markets arm. As of 2025, the firm maintains a national footprint in real estate development, leveraging Mitsubishi’s global network in capital markets and data‑center investments. This alignment supports its long-term strategy in institutional‑grade multifamily, student, senior, medical office, and industrial real estate.
