• Arlene Farkas, the ex-wife of real estate heir Bruce Farkas, has dropped the price of her 14-room duplex at the River House, which she first put on the market in November for $15 million after a state appeals court turned down her ex-husband's appeal to retain ownership of the apartment. The co-op is now listed for $13.5 million. [Cityfile, BHS]
• The apartment where Josh Hartnett had been living until recently is up for sale (or rent). The 2,200-square-foot pad at 237 Lafayette Street, which is owned by music execs James Dowdall and Rose Noone, is available for $2.1 million. Or you can rent it for $7,995 a month. [NYO, Citi Habitats]More

The biotech venture capitalist, who paid $30 million for a duplex on the building's 18th and 19th floors last April and re-listed the spread for $90 million a few weeks later, is now renting out the apartment for $75,000 a month.
