Crescent Heights Inc. is fighting the proposed $19.5 million sale of Miami developer Renzo Renzi’s prime Brickell area site.

The Miami company has asked the bankruptcy judge in Chapter 7 cases involving two Renzi-managed companies to reject the sale to Crystal Tower on Brickell Plaza LLC. Crescent-managed lenders currently hold an $18.2 million foreclosure judgment against the Renzi companies and want a July 31 foreclosure auction to proceed as scheduled.
