LAS VEGAS (AP) – The Las Vegas estate of entertainer Wayne Newton is up for sale amid uncertainty over what potential buyers will get. The Las Vegas Review-Journal reports for sale signs went up Friday at Newton’s Casa de Shenandoah.

Under a procedure approved by U.S. Bankruptcy Court Judge Bruce Markell, prospective buyers must post a 5 percent cash deposit of their proposed price by May 15. An auction is scheduled May 31.

Newton has appealed the sale order. The three houses on the 38-acre property have leases and Newton’s Arabian horses have a right to graze on the land.

Markell has said that trying to sell the property with such conditions would be challenging.

Plans to convert the estate into a theme park celebrating Newton’s career collapsed last year.
