Singer-songwriter Carly Simon reportedly is placing her two-bedroom co-op unit in Manhattan's West Village on the market for $3,800,000. The New York Post's fine celebrity real estate columnist Braden Keil broke the story today of Simon's listing of her co-op unit at 46 Commerce Street in the West Village. Keil reported that the unit measures about 1,200 square feet, and that Simon gut-renovated the apartment, which is in a three-unit building, after she bought it in 2004. We can't find a current listing sheet for the unit, but we'll of course take Keil's word for it. Indeed, New York magazine reported back in April 2004 on Simon's purchase of the unit (actually two units), and described Simon's space at that time as measuring about 1,300 square feet. And, the New York Observer reported in June 2004 on one of the two units (measuring 600 square feet) being sold to Simon. Simon famously was turned down in 2003 in her effort to buy a one-bedroom apartment for $990,000 in the celebrated Dakota co-op building at 1 W. 72nd Street in Manhattan. Simon also owns -- and apparently, according to Keil, now is living nearly full-time -- a place on Martha's Vineyard. That homestead is at 222 Shubael Weeks Path in Vineyard Haven/Tisbury, Mass., according to public records. Check out what is easily our favorite Carly Simon video -- her singing one of her best songs, the poignant 'Coming Around Again/Itsy Bitsy Spider' (in a 1987 performance on the Vineyard, natch) here.
