The deal to sell West Glen Town Center to a Nebraska investment group would have resulted in a significant loss to lenders. Agman Holdings LLC filed a lawsuit Tuesday in U.S. District Court in Des Moines seeking an order that would force West Glen I LLC and West Glen Town Center LLC to close on a deal signed in November 2011 by Gary Kirke, who leads a group of five businessmen who developed the West Des Moines shopping, entertainment and residential district. According to the lawsuit, the investment partners agreed to a price of $38.5 million. On Monday, Agman said it was notified by an attorney representing the owners that the deal was off. West Glen spokeswoman Jamie Buelt said Agman attempted to discount the price by $8.5 million, violating the terms of the purchase agreement. Either amount would have meant a loss to lenders. Missouri-based Midwest Independent Bank obtained a $26 million judgment last year on the second phase of the $100 million development. A sheriff’s sale on that property can occur after Jan. 31. Also last year, U.S. Bank placed a loan on the first phase of the development in special servicing, indicating it was considering a foreclosure. The balance due on that loan was $34 million in November 2010.
