Bel Air is perhaps the destination for billionaires to invest in a brand-new private enclave. Located between Brentwood and Beverly Hills Post Office, Bel Air meanders through the lower foothills of the Santa Monica Mountains, dotting the hills with unmatched-in-luxury, multi-million-dollar estates.

This neighborhood is almost entirely residential, so you won’t feel like you’re living in a city, despite the proximity to Los Angeles and Hollywood. In fact, the neighborhood is penned in by a large gate, with only two elegant stone entryways. All this contributes to the feeling of being inside a beautiful hideaway.

The residential crowd is made up of… some of the most opulent homes you’ve ever seen. While there are a fair number of smaller mansions, you won’t be hard-pressed to find estates with multiple wings and stories and expansive views. Most homes are hidden from the street with high walls, fences, or shrubbery.

The lifestyle offered is… private and extravagant. Residents in Bel Air don’t spare any luxury in their homes and lifestyle—and why should they?

The most popular building type is… modern mansions with every comfort you could imagine and extensive security. The average home price is… $3.5 million. But there will also be several homes priced above $20 million (and in 2017, Bel Air boasted the first home listed for $250 million!).

The area’s greatest highlight is… the seclusion and exclusivity of living within one of the world’s most prominent gated communities.
