Legendary singer-songwriter Neil Finn, Crowded House frontman and Fleetwood Mac’s newest member, has purchased an impressive new house on L.A.’s Eastside, in the perennially expensive and celeb-beloved community of Los Feliz. Records reveal Finn and longtime wife Sharon paid $4.3 million for the property, which was sold by Emmy-winning “Simpsons” writer Tim Long, former head writer for “The David Letterman Show.” And from 2007 to 2013, the house was owned by erstwhile “Grey’s Anatomy” star Katherine Heigl.
