The Mountain Of Bev Hills $400 Million Offer Rejected By Owners That's Chump Change, Bro

There's a real estate battle brewing for the most expensive property in the history of Los Angeles, fittingly dubbed "The Mountain," because we've learned the owners of the incredible mountaintop property just laughed off a developer's $400 MILLION offer!!!

Sources familiar with the negotiations tell TMZ ... builder Scott Gillen recently submitted a $400 mil bid, but the estate's ownership group scoffed and came back with a $600 million counter!

It's interesting ... "The Mountain" is listed for $1 BILLION, but the counteroffer from ownership group Secure Capital Partners is $400 mil below the 10-figure asking price. Overvalued much?

Gillen tells us, "I saw an opportunity to expand my brand in the city, something I've wanted to do for some time. If they're smart, they'll take the offer."

We're told Gillen has grand plans to build 6 homes on the sprawling 157-acre plot of land in Bev Hills, which sits atop a mountain overlooking all of L.A. ... while the owners envision a single home being built on the 1.5 million square foot property. Regardless, the impasse is all about money.

Scott's no stranger to massive land purchases. Last year, he set a Malibu real estate record when he plunked down $50 mil on a 24-acre plot. Still, we're told "The Mountain" deal is likely going nowhere because Gillen doesn't want to budge.

We reached out to the listing agent, Aaron Kirman, who had no comment.

The good news ... if you're part of the 3 comma club, "The Mountain" could still be yours!
