Allston-based City Realty Group won a bidding war for a nine-building portfolio of retail and residential buildings in Brookline’s Coolidge Corner.

The portfolio spans 65,262 square feet and includes 49 residential units and three commercial spaces. The purchase price was $23.15 million.

Colliers represented the seller, Ramon Realty of Brookline.

“The depth of interest we saw throughout the process, despite uncertainty surrounding the proposed rent-control ballot initiative, speaks to investors’ conviction in Brookline and the opportunity for the portfolio to create additional value through continued unit improvements,” Colliers Managing Director Frank Petz said in a question.

The property was placed under agreement prior to dismissal of a statewide rent control ballot question. The offering attracted interest from local, regional and national multifamily investors, Colliers announced.

The portfolio is 96 percent occupied. It includes properties at 223 and 229-231 St. Paul St, 26-28 Browne St., 395-397 Harvard St., 7 Naples Road and 1343 Beacon St.

Editor’s note: This report has been updated to clarify the property was placed under agreement while a statewide ballot question for rent control was in play for inclusion on the November ballot.
