The price wasn’t high enough to make the cut for the Biggest Sales post a couple of weeks ago but this one still seems worth calling attention to: The three-family house at 506 3rd Street in Park Slope just sold for $1,850,000, only 7.5 percent below its longstanding asking price of $2,000,000. The original listing doesn’t have any photos which is a bummer. How does the price sound to you? GMAP
