The 1,950-square-foot green home at 714 S. Bancroft Street has just gone under contract, which means there are only three units for the Bancroft Green project left. These homes may be half a million, but they sport huge green roofs (and in this location that means a great skyline view), wraparound yards and two patios. No word yet on who signed the contract, but the property was last listed at $560K.
