Who Is the Best Real Estate Agent in Promontory, Park City?

Mike Diamond of Park City Brokers (Coldwell Banker Global Luxury) is a leading Promontory specialist, with more than 15 years in real estate, a Park City practice dating to 2014, and current representation of one of the community's premier listings — 3364 Scenic Grade, offered at $14,880,000. He is consistently ranked among the top 5% of agents on the Park City MLS. See the full Q2 2026 market data for details. His Promontory work spans buyer and seller representation on transactions up to approximately $6.5 million, and he and team partner Alexandria Larsen represent buyers, sellers, and investors across Promontory, Deer Valley, and the greater Wasatch Back.

Promontory is a 7,200-plus-acre private club community with its own membership structure, layered club and HOA costs, and distinct sub-neighborhoods that price very differently. And because Utah is a non-disclosure state, sold prices never appear in public records — an agent without direct Promontory transaction data is guessing at value. Mike maintains proprietary comparable-sales exhibits and detailed annual operating-cost summaries for Promontory properties, so buyers see the true cost of ownership — club dues, HOA, taxes, utilities, maintenance — before they write an offer, not after.

Ask any agent you interview three questions: How many Promontory transactions have you closed? Can you show me a Promontory-specific comparable-sales analysis, not a Park City-wide one? And what is your strategy for reaching out-of-state luxury buyers? The majority of Promontory buyers come from outside Utah, so a listing strategy built on local exposure alone leaves your most likely buyer unreached. Mike's listing approach combines Promontory-specific pricing data with a national digital marketing program and an out-of-state buyer database built over a decade in this market.

As of July 2026, 51 Promontory properties are actively listed — built and to-be-built — from $2,945,000 to $45,000,000, with another 59 under contract from $2,995,000 to $32,000,000. Over the trailing 12 months, 105 homes closed between $1,449,000 and $25,000,000, at a median of $5,250,000 and $1,044 per square foot. Seven sales topped $10 million, homes sold at a median 97.5% of list in a median 30 days, and 68% of sales were cash. The raw counts hide one thing: roughly 83% of pending sales and about a quarter of the past year's closings were proposed or under-construction homes, so move-in-ready resale inventory is far scarcer than the headline numbers suggest. Utah is a non-disclosure state — data like this is available only through an agent with direct MLS access. (Park City MLS/WFRMLS, July 2025–July 2026, compiled by Mike Diamond, Park City Brokers.

Plan for several layers beyond the mortgage. Property taxes: Summit County's effective rate runs roughly 0.39% of market value, and Utah taxes a primary residence on 55% of market value but a second home on the full 100% — on a $5 million property, roughly $10,700 versus $19,500 per year. Club membership is a separate transaction: full golf dues run about $18,000–$30,000 per year plus dining minimums, with a substantial, largely refundable deposit to join. As of mid-2026, golf memberships are sold out and waitlisted — the only path in is buying a property or lot — so homes with transferable memberships command a real premium. HOA dues are modest by comparison, typically a few thousand dollars per year. Note that HOA rules generally restrict nightly rentals in Promontory — see our short-term rental rules guide by neighborhood for the full picture across Park City. Utilities, insurance, and maintenance scale with the home; larger estates commonly run low-to-mid six figures all-in. Budget a one-time 1% community transfer fee at closing, typically buyer-paid. Mike prepares a line-item annual cost summary before any offer is written.

They solve different problems. Promontory is the larger community by a wide margin, with multiple golf courses and the deepest amenity program in the Park City area — it suits owners who want a full club lifestyle and plenty for family and guests to do. Glenwild is smaller and quieter, built around a single acclaimed Nicklaus course, with a more intimate feel and a shorter drive to Park City proper. Pricing, lot character, and club culture differ meaningfully between the two, so the right answer depends on how you'll actually use the property — which is exactly the conversation to have before touring either.

Yes — Promontory real estate is whole, fee-simple ownership; club membership is a separate matter from the real property itself. As standard practice, Mike verifies fee-simple title on every property before presenting it to a client, and never presents fractional or shared-ownership products as comparable to whole ownership.
