It looks like 20 Pine Street and Rector Square aren't the only downtown apartment buildings facing lawsuits from frustrated, angry buyers. Steve An paid $820,000 for an apartment in mogul Lev Leviev's District condo building at 111 Fulton Street back in 2007. Maybe he isn't so impressed with how Amy Sacco's "exclusive lifestyle concept" has been turning out? An filed suit against Leviev's company on Tuesday, and is now demanding his $82,000 deposit back. You can look at the complaint for yourself below.
