Bubble, bubble, toil and trouble — could it be that New York's real-estate market isn't as hot as so many brokers say it's gotten? According to PropertyShark, it depends on the neighborhood. The data-rich real-estate site offers a "Triple Bubble Trouble" city map, marking which Zip Codes suffer from three signs of a real-estate bubble perhaps set to burst: decreasing prices per square foot, increased foreclosures, and a slowdown in the volume of sales in the first quarter of this year compared to the previous three months. Which neighborhoods show a triple whammy? Some surprising areas, like Midtown East and the far West Sixties. "The market's softening up in some places," says PropertyShark CEO Ryan Slack. "Everything falls sometime." —S. Jhoanna Robledo
