Kanye West and Kim Kardashian just made a fortunate on their Bel-Air mansion.

According to TMZ, the power couple has sold their 1-acre property for $17.8 million, an increase from the $9 million they spent on the 10,000 square foot home in 2013.

The numbers make history. In fact, it is reportedly the most expensive sale ever in the Bel-Air Crest community. The buyer is Ukranian philanthropist/musician Marina Acton.

Realtors Matt and Josh Altman from Bravo’s “Million Dollar Listing L.A.” represented the buyer and seller in the deal. Escrow closed in the past week.

Now, Kim and Kanye are reportedly moving to Hidden Hills. The couple has a home in the area that they’ve been working on for years.
