Class B office space at 258-262 Washington St. and 85 Devonshire St. in Downtown Crossing could fetch in excess of $525 PSF. The Class B office market in the Financial District has seen strong rent growth over the last 36 months with prices ranging from the upper $30’s to the upper $40’s PSF.

From the Boston Business Journal:

The buildings together encompass about 92,000 square feet and span the stretch of Water Street between Washington and Devonshire streets near the State Street MBTA stop…Boston-based real estate investment and development firm KS Partners owns the property and has invested more than $5 million in the past three years to help rejuvenate it.

Marketing materials obtained by the Business Journal indicate that the the Washington and Devonshire property is “one of the last Downtown Class B repositioning opportunities” that is “an opportunity to capture momentum” for retail repositioning along Washington Street. The stretch of Washington Street fronts the Freedom Trail and is currently leased by a Subway and a Vitamin Shoppe.
