Luxurious Nevada Mansion With a Monthly Electric Bill of Just $20 Snags Buyer Within Days of Listing for $3.9 Million

An opulent desert mansion that sits just minutes from the bright lights of the Las Vegas Strip—but has a monthly electric bill of only $20—has been scooped up by an eager buyer mere days after it hit the market for $3.89 million.

The five-bedroom residence, which spreads across 5,919 square feet of luxurious space, features a fully owned solar system that not only keeps energy bills at an absolute minimum, but even allows the owners to accrue credits that they can use to offset their costs.

With energy costs at an all-time high—up 13% in 2025 alone, according to a report from Climate Power—the Henderson, NV, property offers resounding evidence that solar power investment really can pay off in dividends, if carried out in the right way.

"It is a paid-off, 75-unit solar system with a monthly bill of around $20," explains listing agent Gianni Sammarco of Huntington & Ellis, who notes that the current owners worked carefully to set up an energy-efficient system that would keep their costs low, even as they resided in the lap of luxury.

"The seller has even accumulated credits because of its low-energy efficiency. When the sellers added the solar system, they were looking to be mindful of costs and wanted energy efficiency," he adds.

Perhaps, then, it is no surprise that the home flew off the market within days of listing on Nov. 7, snagging a buyer who will not only enjoy low-cost living, but also an unparalleled lot that has ample room for expansion.

“This energy efficiency is almost unheard of at this level,” Sammarco says. “Combined with its oversized lot, with room to add an additional structure, the property stands out as one of the strongest opportunities in Henderson today.”

Built in 2018, the Blue Heron-designed estate is nestled in the guard-gated Seven Hills enclave, which sits atop a hill, providing spectacular vistas.

The property is perched on the edge of a man-made lake, creating a tranquil environment, despite it sitting just minutes from the hustle and bustle of Sin City.

All of that, combined with its sleek and modern aesthetic, led its listing agent to realize he had a winner on his hands.

"The views of the lake, mountains, and Las Vegas Strip are what make this home so unique," Sammarco adds. "I think the architecture type, modern finishes, energy efficiency, and price point are what attracted a buyer so quickly."

The contemporary sits on an oversized lot with serene views overlooking Serket Golf Club and a golf course pond.

"When we listed the house, I envisioned the buyer to be someone who is eco-friendly, looking for a view, and a modern-type property," Sammarco said. "Henderson connects with Las Vegas, is about 12 minutes away from the Strip, and is one of the safest neighborhoods in the country."

Highlights found throughout the modern interior include clean lines, high ceilings, and pocket glass doors, offering a seamless transition to the outdoor living area.

Lavish amenities include a climate-controlled wine room and a separate casita that could be used as a yoga studio, home office, fitness center, or private guest suite.

The two-story living room has retractable glass walls that open up to a spacious patio designed for relaxing and entertaining while enjoying the spectacular surrounding scenery.

A gourmet chef's kitchen with custom cabinetry boasts a waterfall breakfast bar and high-end appliances, including a double oven.

An opulent primary suite with private covered terrace has a stunning natural stone soaking tub, an indulgent marble steam shower, and a boutique-inspired, walk-in closet.

Several outdoor lounging areas overlook the in-ground pool and hot tub. Two garages provide parking for up to four vehicles.

Designed for entertaining, the rooftop area is the perfect spot for soaking in the breathtaking desert sunsets, valley views, city lights, and nearby Strip fireworks.

"For a buyer seeking elevated design with true functionality, this is a remarkable opportunity,” he added.
