The landmark purchase at 607 Alpine Summit Drive represents the largest residential transaction in huntington & ellis history and reinforces Sammarco’s position among Las Vegas’ leading luxury real estate advisors.
Gianni Sammarco, a luxury real estate advisor with huntington & ellis, represented the buyer in the $13.4 million purchase of 607 Alpine Summit Drive in MacDonald Highlands. The October 2025 closing was the largest residential transaction in huntington & ellis history and was identified by the Las Vegas Review-Journal as the highest-priced Las Vegas home sale of the month.
Located within The Peak at MacDonald Highlands, the 8,258-square-foot residence closed for approximately $1,623 per square foot. Successfully representing a buyer at this level requires far more than identifying the right property. It demands discretion, detailed market knowledge, strategic negotiation and the ability to manage the complexities associated with an eight-figure transaction.
For Sammarco, the milestone represents the continuation of a 20-year real estate career built around serving buyers and sellers in Summerlin, Henderson and Southern Nevada’s most distinguished guard-gated communities.
“Gianni has established himself as one of the most accomplished independent agents at huntington & ellis, and this transaction reflects the experience and professionalism he brings to his clients,” said Craig Tann, founder and owner-broker of huntington & ellis. “Representing a buyer in an eight-figure purchase requires an exceptional level of trust, discretion, market knowledge and execution. We are incredibly proud to have Gianni representing our company at this level.”

Inside the $13.4 Million MacDonald Highlands Purchase
The six-bedroom, seven-bathroom residence offers garage and carport parking for eight vehicles, a 1,324-square-foot pool and spa, a sky deck, an outdoor kitchen and expansive pocket doors that create a seamless connection between the home’s interior and outdoor living spaces. Fire and water features complement panoramic views of the Las Vegas Strip and surrounding mountains.
The home is positioned within The Peak, an exclusive enclave inside MacDonald Highlands. The guard-gated Henderson community is built around DragonRidge Country Club and its championship golf course. MacDonald Highlands is known for its elevated homesites, custom architecture, privacy and sweeping views of the Las Vegas Valley.
A single-family transaction exceeding $13 million is notable in any market. The Alpine Summit purchase demonstrates that distinctive, well-positioned luxury properties in Henderson continue to attract qualified buyers who recognize the long-term value of location, design, privacy and views.
The Experience Behind an Eight-Figure Transaction
At the ultra-luxury level, successful representation extends well beyond showing homes and preparing contracts. Buyers need an advisor who can evaluate a property within its specific luxury submarket, understand the value of features that may not be reflected in broader market data and coordinate a complex transaction with discretion.
Sammarco’s role included helping his client evaluate the property, understand its position within MacDonald Highlands and navigate the strategy and details of a significant purchase. His familiarity with Henderson’s luxury communities gave the buyer local context that cannot be captured by price-per-square-foot comparisons alone.
“At this level, clients expect discretion, preparation and a clear understanding of value,” Sammarco said. “My responsibility was to help my client evaluate not only the property, but also its position within the MacDonald Highlands market and the long-term value of the opportunity. It was a privilege to represent my client in such an important purchase and to be part of a milestone transaction for huntington & ellis.”
A Second-Generation Las Vegas Native
Sammarco is a second-generation Las Vegas native whose connection to Southern Nevada gives him a detailed understanding of the neighborhoods, developments and market conditions that shape the region’s luxury real estate market.
Over the course of his 20-year career, he has built his business around personalized representation for luxury buyers, sellers, executives, families and clients relocating to Nevada. His work is concentrated in Summerlin and Henderson, including MacDonald Highlands, The Summit Club, The Ridges, Red Rock Country Club, Ascaya, Green Valley and other guard-gated and custom-home communities throughout the Las Vegas Valley.
Each community has its own inventory, amenities, architectural standards, location advantages and buyer profile. Sammarco helps clients understand how those differences influence property values, lifestyle and future marketability.
Gianni Sammarco’s 2025 Real Estate Results
The Alpine Summit purchase was the defining transaction in a standout year for Sammarco. In 2025, he closed $24,442,000 in total sales volume with an average sales price of $2,715,777.
He finished the year as huntington & ellis’s No. 1 independent agent and No. 6 agent overall companywide. He was also ranked No. 68 in Nevada on the 2025 RealTrends Verified list and has previously been recognized as a Las Vegas “40 Under 40” honoree.
What Luxury Buyers and Sellers Can Learn From the Sale
For sellers, the Alpine Summit transaction demonstrates the value the market can assign to an exceptional combination of location, architecture, privacy, elevation and views. However, even the most distinctive luxury homes require thoughtful pricing, elevated presentation and a strategy designed to reach the right audience.
Sammarco evaluates luxury properties within their individual submarkets rather than relying solely on valley-wide averages. In communities where custom construction, lot position, golf frontage, architecture and Strip views can dramatically affect value, that distinction matters.
For buyers—particularly executives, families and high-net-worth individuals relocating to Nevada—representation requires an understanding of more than the house itself. Community differences, comparable sales, contract strategy, inspections, timelines, privacy and long-term marketability all factor into an informed purchase.
