Real estate brokerage Redfin piloted a program in Boston that allowed unrepresented homeowners to sell homes through their website; sellers would accept a 2 percent commission instead of the customary 4 percent; they now plan to make this program available nationwide one market at a time; the buy now button idea is not new for the company, they originally tried the idea back in 2006 but it went nowhere; real estate is still a slow process with multiple parties and reams of paper, though changes are beginning to make it more efficient.
