Buyers Met by Medieval Knight Giving Tours of Washington Castle for Sale

If you're after a knight in shining armor, this four-bed, four-bath house in Washington is for you.

Realtor Jonas Elber, of Elber and Associates, gave the home at 12227 E. Tallman Road, Chattaroy, which was on the market for $600,000, a unique talking point by having a knight stage the photos.
