Apartment buildings bought during market peak might default 

At the peak of the housing market, big developers bought up rent-stabilized buildings, and some now fear those buildings will default. The Riverton Houses in Harlem depleted its debt service reserve fund, and Stuyvesant Town could have the same fate in several years. Other buildings being watched include Harlem’s Savoy Park apartments, formerly the Delano Village complex, which has $367.5 million in debt after selling for $175 million in 2006.
