The radio may be on its way out, but Casey Kasem's bank account is about to sky rocket!
The radio host is unloading his massive Bel Air mansion ... and if you've ever wondered what $42 million of property looks like, just check Kasem's home-sweet-home.
Casey will definitely be making a huge profit on his former home -- the 80-year-old purchased the house in 1989 for just $1,725,000!
The 12, 000 square-foot estate boasts 7 bedrooms, 11.5 bathrooms, a library, bar, double master suits, hair salon, 2 swim pavilions, guest house and a tennis court.
Our favorite part of this beautiful Bel Air abode -- the backyard which sits on acres of green landscape, outfitted with a stunning heart-shaped pool and relaxing patio area all surrounded by giant trees for complete privacy.
Those radio guys sure make bank. Ryan Seacrest bought his Beverly Hills home from Ellen DeGeneres and Portia de Rossi for $49 million. Talk about golden voices!
