It's going to get worse before it gets better

for Manhattan real estate:

At 304 Spring Street, a sleek condominium building in SoHo with stunning Hudson River views, the buyer for the duplex penthouse recently decided he would not go through with the deal and walked away from a $780,000 deposit.

At 1120 Park Avenue, a classic prewar co-op filled with multimillion-dollar apartments, it appears that a buyer forfeited a deposit of as much as $1.1 million.

Real estate agents representing buyers of at least three other multimillion-dollar properties also report clients who knowingly left deposits of more than $1 million or hundreds of thousands of dollars on the table.

In each case, the buyers had signed their contracts before the financial meltdown last fall, but decided in recent months that because values in the luxury real estate market have dropped 20 to 40 percent, it no longer made sense to go through with their deals.
