X17online can report exclusively that Khloe Kardashian is set to SELL the Tarzana mansion she's shared with Lamar Odom for the past four years.

We caught the real estate agent on his way to Khloe's neighborhood just an hour ago and he told X17online exclusively, "I'm going to meet with Khloe right now, but I'm not sure if Lamar is going to be there or not." The realtor added that Khloe plans on listing the house for $3 million, and his commission will be $100,000. Seeing as that is nearly $1 million less than what they paid for it, it looks like Khloe is really looking to unload the place -- and quickly!

Today is the duo's four-year wedding anniversary, but given that she's putting her pad on the market (and dropping the Odom from her online handles), it looks like these two are definitely headed for divorce.

The couple purchased the 8,347-square-foot home in December 2009 for $3.95 million, and it has 7 bedrooms and 9 bathrooms. The home sits on .75 acres of land on a gated cul-de-sac, and it has a lush lawn, a large pool, parking for up to 15 cars and according to listing information, it's "one of the finest homes in Mulholland Park!"
