Last week Elon Musk threatened to sell "almost all physical possessions" in a potentially illegal Twitter meltdown that cost Tesla an estimated $14 billion.

Surprisingly, he appears to have come good on at least part of the claim by relinquishing himself of some of his real estate. And though he says he doesn't need the money, he's poised to make millions.

"Don't need the cash. Devoting myself to Mars and Earth. Possession just weigh you down," he tweeted. Nevertheless, two of his properties appeared on Zillow this Sunday for a combined asking price of $39.5 million.

The first is a 20,000-square-foot Bel Air mansion that Musk originally bought for $17 million. Today, however, it's listed for a cool $30 million. The Lower Bel Air Estate boasts ocean views, a two-story library, theater, lighted championship tennis court, wine cellar, gym, pool, fruit orchard, and motor court with a five-car garage.

The second property was formerly owned by Hollywood legend Gene Wilder and is listed for $9,500,000. The property is a 2,800-sq.ft. 5-bedroom, 4.5-bath ranch home with oval pool and private guest cottage, according to the description on Zillow says.

According to The Wall Street Journal, Musk and companies affiliated with him have spent an estimated total of $100 million on seven houses since 2012.
