In Tuesday's auction, the John Deere House in Moline was sold to SaukValley Bank in Sterling for $167,000. The bank, which recently foreclosed a mortgage on the house, offered the only bid on the property.
John Deere purchased the house from grocer William Dawson in 1875, and spent the next five years more than doubling its size.
It was purchased by the City of Moline in 1993.
Roger Colmark bought the Deere house from the city for $100 in 1996 and planned to restore the home to how it looked when John Deere lived there, but the restoration was never completed. Foreclosure proceedings began last year.
