CHICAGO—Locally-based Boulder Group, a national single tenant net lease investment brokerage firm, has been selected as the exclusive advisor for the sale of a Walgreens portfolio consisting of six properties, offered for $49 million.

The properties are located in Clinton and Lakeville, Mass.; Belfast, Maine; Columbus, Ohio; West Columbia, S.C. and Rochester, Minn. The portfolio is being offered on a “free and clear” basis, according to Boulder President Randy Blankstein in a statement.

“This portfolio represents a rare opportunity for an investor to acquire a large portfolio of long term triple net leased Walgreens properties” said Blankstein. His firm sold a similar Walgreens portfolio for $68.7 million in June 2012.

Both Blankstien and Jimmy Goodman are marketing the portfolio on behalf of a private investment company. Blankstein said there is no debt that needs to be assumed. Each property is fully leased to Walgreens on a long-term basis with an average lease term of 21 years.
