Downtown-based CBRE Global Investment Partners has acquired a 95 percent interest in a 25-building U.S. medical office portfolio, the company announced Wednesday.

The portfolio comprises medical office buildings across 10 states totaling 1.4 million square feet of existing space and a 150,000-square-foot development project, the company said.

The properties include multiple buildings in Atlanta and Chicago. The portfolio is about 95 percent occupied, with key tenants including both national and regional healthcare systems along with high-quality specialists, according to the firm.

The firm is an arm of downtown’s CBRE Global Investors, ranked No. 10 on the Business Journal’s list this year of largest money management firms based on assets managed in Los Angeles County in 2016, with $86.6 billion in assets.

“The medical office sector has seen strong demand due to demographic drivers that have heightened consumer demand for health care,” said Ian Gleeson, CIO of CBRE Global Investment Partners, in a statement.
