A joint venture between three real estate firms has acquired a Princeton office building, it announced recently.

Woodbridge-based Bergman Real Estate Group teamed with New York-based Hornig Capital Partners and Florida-based Eightfold Real Estate Capital to buy the four-story, 160,000-square-foot building at 500 College Road E. in the Princeton Forrestal Center from Mack-Cali Realty Corp. Mack-Cali has been selling off its suburban office assets as part of a portfolio refocus, and the deal represents Bergman’s third acquisition from the REIT.
