You don't have to be able to sing your heart out to own the former Upper West Side home of jazz great Billie Holiday, but you will need more than twice as much as you would have six years ago. 26 West 87th Street, sitting less than a block west of Central Park, has six floors (if you include the garden and basement levels). Holiday, known to many as "Lady Day," made this her residence until her untimely death at age 44, generally believed to have been the result of substance abuse. (She actually died at Metropolitan Hospital on the East Side.) There are whopping seven bedrooms, six full bathroom, and two powder rooms. The L-shaped stoop, impressive enough with its two landings, will do an owner one better because it is heated. That means less shoveling in the winter. Original details remain, including plaster moldings, wood paneling, a grand staircase, and fireplace mantels. New windows, plumbing, electrical, and HVAC have brought this mansion into the 21st century. It can all be yours for $12.95 million, a big increase since its sale in 2009 for $5.85 million.
