Promontory’s ZIP Code, 2020 to 2026
Public data can answer the area question, not the club question. The ZIP code that contains Promontory, 84098, rose 70.1% from February 2020 to August 2026, reaching a typical home value of $1,382,166, per [Zillow Research’s ZIP-level index](https://www.zillow.com/research/data/) retrieved October 4, 2026. That is ahead of Salt Lake City’s 84106 at 50.2% and Holladay’s 84117 at 51.9%, and behind Old Town Park City’s 84060 at 104.6%. The most recent twelve months added 4.8%, a far calmer market than the one that produced the six-year figure. No public index measures Promontory itself: 84098 covers much of the Snyderville Basin, and club membership and dues sit outside every number here. This report publishes the series, then states the four things it cannot settle for a specific home.
