Boeing officials say they will begin actively marketing the company's Wichita defense facilities by the end of January.
The company announced last year that it was closing the Wichita plant and moving work to Oklahoma, Texas and the Pacific Northwest.
Boeing owns 97 buildings on 413 acres, with properties ranging from large hangars to tool sheds.
Company spokeswoman Kathleen Spicer says Boeing is working with national real estate firm CBRE Group of Los Angeles to arrange the sale of the property.
The Wichita Eagle reports that Boeing has done some site preparation work, including separating utilities and some environmental remediation. Spicer wouldn't say how much interest the company has received.
Boeing closed its Wichita commercial aviation business in 2005 and has concentrated on military programs since then.
