The town released applications today via a consultant for the affordable housing unit at Wellesley Commons, a five-unit condominium complex at the corner of Washington Street and Hillside Road.

The affordable unit, which falls under the parameters of Chapter 40B of Massachusetts General Laws, is a 1,800 square-foot, three bedroom, 1.5 bathroom townhouse with a two-car garage, according to the application.

The unit will be sold for $143,000 with a monthly condominium fee of $135.

The unit will be sold to a family whose income is within 50 percent within the area’s median income and whose assets do not exceed $75,000, according to the application.

The lottery will be held by Steve Burtt of Housing Options, Wellesley Commons’ consultant, July 23 at 7:30 p.m. at Town Hall.

The property has gone through several changes, stalls and even protests since 2007 due to violations. Originally, the property was set up as a non-40B four-unit condominium complex. In 2007, the Board of Selectmen rejected Roslindale developer Michael Connolly’s application, but the state overturned the decision a year later, allowing it to become a five-unit 40B eligible complex.
