Both are Shea Homes Trilogy 55+ communities in Las Vegas. Both are gated and resort-style. But the price gap, location, product type, and availability are meaningfully different — here is every real distinction between them.
Shea Homes markets both under the Trilogy brand, which leads buyers to assume they are essentially the same product at different addresses. They are not. Trilogy in Summerlin is a 354-home attached condo and villa community that sold out years ago — every transaction is resale. Trilogy Sunstone is a 933-home single-family detached community still under active construction where buyers can still purchase new. The price difference is $100K–$200K in Sunstone’s favor at equivalent specs.

At comparable specs and finishes, Trilogy Sunstone homes run $100K–$200K below Trilogy in Summerlin. Two factors drive this: location premium (Summerlin’s established master plan commands a premium over the newer northwest corridor) and product type (Trilogy in Summerlin’s higher HOA reflects exterior maintenance being included — a cost Sunstone owners pay separately).
When yard maintenance is included, the true all-in monthly cost difference nearly disappears at the same purchase price. The real financial decision is not HOA vs HOA — it is $650K attached condo at Trilogy Summerlin versus a detached home that costs $650K at Sunstone (which is toward the upper end of Sunstone’s range). Most buyers comparing these two communities are actually choosing between a $600K Summerlin condo and a $450K–$550K Sunstone detached home, where the price gap is larger and more impactful.
Both communities deliver the Shea Homes Trilogy experience. The decision is a lifestyle and financial values question, not a quality question.
