A downtown Englewood shopping center owned by a spinoff of real estate giant Vornado is in default of a 9-year-old mortgage, according to a lawsuit filed by the mortgage holder that is seeking $13.2 million in principal and interest. The foreclosure demand, filed last Tuesday in U.S. District Court in Newark, claims that the borrower, listed in court papers as UE Shoppes on Dean LLC, defaulted on the loan in April and since then has not made the required monthly payments to the loan holder, U.S. Bank National Association of Cincinnati.
