Abigail Disney, Walt Disney’s grandniece, has sold her pair of 300 West End Avenue co-ops for a combined $7.2 million, but not before a string of hefty price cuts. Disney purchased the two semi-combined, nine-room units from singer Harry Belafonte for $10.75 million in 2006. They hit the market again in April 2008 for $13.45 million. The price was cut to $11.95 million, and then to $10.95 million, before finally selling last month to two separate buyers. Amy Gold and Brett Gorvy, deputy chairmen at Christie’s, purchased the B-line apartment for $3.45 million, and the A-line apartment sold for $3.75 million. Dolly Lenz of Prudential Douglas Elliman had the listing.
