The bill is coming due for the Chetrit Organization and Stellar Management on the Upper West Side.

Shareholders of a $400 million mortgage backing the Columbus Square shopping center filed a lawsuit seeking to foreclose on the property, Crain’s reported. The move comes months after ownership defaulted on the debt at the outdoor shopping center, stretching from West 97th to West 100th Street on Columbus Avenue.
