The $40 Million Paradise Valley Estate With Its Own Indoor Go-Kart Track

In Paradise Valley, Arizona, luxury is often measured in mountain views, architectural pedigree and resort-style living. But at 5531 E Mockingbird Lane, the definition stretches a little further. This is not simply a home with impressive entertaining space. It is a private playground on a cinematic scale.

Listed for $40 million with Local Luxury, an affiliate of Christie’s International Real Estate, the estate is currently being presented as the most expensive property on the market in Paradise Valley. Set across nearly two acres with sweeping views of Mummy Mountain, the residence spans more than 20,000 sq ft, with an additional 6,000 sq ft of garage space designed to house up to 18 cars.

Designed by Candelaria Design and built by Arcadia Custom Builders, with recently completed phase two interiors by Katie Bowe Design, the property has been created with entertaining at its heart. Every detail feels considered for a lifestyle where privacy, comfort and spectacle exist side by side.

The headline feature is impossible to ignore: an indoor go-kart track. Rare even by ultra-prime real estate standards, it gives the home a sense of playful extravagance that immediately sets it apart from the more traditional language of luxury estates. This is a residence designed not only to impress, but to be enjoyed.

Inside, the scale continues. The lower level features 10 ft ceilings, a lounge and bar, theatre, salon and spa, sauna, massage room, shooting range, safe room, and dedicated indoor recreation spaces, including the go-kart track and children’s playground. It is less a basement than a private leisure complex.

The main residence balances this sense of spectacle with polished design. White oak floors, rift oak cabinetry, Sierra Pacific windows and doors, a chef’s kitchen, prep kitchen and butler’s pantry create a refined domestic backdrop. Dual 432-bottle wine walls add another layer of entertaining appeal, while Control4 automation, whole-home audio, gated entry and cameras bring a sense of ease and security.

Accommodation is equally generous, with eight bedrooms, seven full bathrooms and four powder rooms. Beyond the main house, a detached guest house offers dual suites, a full kitchen and laundry, while a separate studio casita provides further flexibility for visitors, staff or extended stays.

Outside, the estate becomes a desert resort. The grounds feature a resort-style pool and spa, a sprawling lawn and a ramada with a full outdoor kitchen, pizza oven, grill, smoker, bar and misting system. It is designed for long afternoons, large gatherings and the kind of indoor-outdoor living that defines the most desirable homes in Arizona.

Yet what makes Mockingbird Lane compelling is not simply its list of amenities, but the way they combine. This is a home for collectors, hosts, families and those who want their private residence to feel as considered as a five-star retreat. It has the architectural credentials, the location and the scale, but it also has personality.

At $40 million, this Paradise Valley estate is not just one of Arizona’s most notable listings. It is a bold reminder that, at the very top of the property market, luxury is no longer just about square footage or finishes. It is about creating a world of your own.
