• A sixth-floor apartment at The Dakota, which is owned by an unidentified "Wall Street executive," has been cut for the third time since hitting the market in June 2008 with a $24 million price tag. The four-bedroom co-op is now listed for a mere $12.5 million. [Cityfile, BHS]
• Investment banker (and onetime deputy mayor) Peter J. Solomon is reportedly the buyer in contract to buy the former East Hampton estate of the late actress Mary Howard de Liagre. Solomon is paying "close to" the $22.5 million asking price for the estate, which includes a 3,500-square-foot home, 300 feet of waterfront, and a dock. [NYP, Sotheby's]
• Investor Enrique Foster Gittes has once again cut the price of his 13,000-square-foot mansion at 12 East 63rd Street. The six-floor townhouse, which Gittes bought for $8.8 million in 2005, put on the market for $28.75 million in April, and reduced to $24.95 million last month, is now on the market with Brown Harris Stevens' Paula Del Nunzio for $23.5 million.

The condo conversion of 20 Pine Street has been plagued with problems for ages. One of the first conversions to come along in the financial district, the Shaya Boymelgreen-developed, Michael Shvo-marketed building was supposed to be finished in 2007. It wasn't, of course, which led to the first lawsuit back in August 2008 when a buyer argued that 20 Pine had been misleading about the building's completion date and had refused to rescind the buyer's contract. The situation hasn't improved much since then: The pool and gym remain unfinished, and just two weeks ago Shvo announced that construction work on the building's amenities would be suspended for a week "to concentrate on completing about 50 residential units." Now it seems other buyers have had enough. A Massachusetts woman who paid $925,000 for an apartment in 2006 (as well as an additional $16,000 for two storage units) filed a lawsuit of her own this week, and is now demanding that her deposit be returned, too. The full suit appears after the jump.
