Brownstone Brooklyn just landed another celebrity homeowner: Grammy Award-winning singer-songwriter Norah Jones closed on an 1843 townhouse in Cobble Hill at the end of January. (We’re not telling you the address.) Jones paid an astonishing $4,990,000 for the restored 4,100-square-foot house, a price that’s hard to fathom even just a few months later (unless, maybe, it includes the parking lot next door). The just-below-asking price was agreed to in early December, well into the depths of the current financial crisis, after the 25-foot-wide house had been on the market for almost six months without a price reduction. She did get a pretty swanky pad for her hard-earned dollars: the parlor floors looks killer, though the nouveau-Tuscany vibe of the renovated kitchen isn’t really working for us.
