Chesley Sullenberger and his wife, Lorraine, claim the $935,000 they paid for a building in the city of Paradise in 2002 was well above its market value. They accuse bank officials and the real estate broker of overinflating the price.
The suit seeks a nullification of the original loan and reimbursement for alleged overpayments. A trial is set for September if mediation talks fail.
The real estate broker, Cherie Huillade, tells the Press Democrat of Santa Rosa the property's appraisal was accurate.
Sullenberger became a hero after safely ditching a jet carrying 155 people in the waters off Manhattan in January 2009.
