Why does a Ketchum home cost roughly $500,000 more than a Hailey home twelve miles down the highway? The portals show the spread. They do not explain it, and buyers who treat the gap as a simple quality discount tend to shop the wrong inventory for months.
The honest answer is that the median is a blunt instrument in a valley where three towns sell three different products. Once you separate the product-mix effect from the location effect, the gap looks less like a verdict on Hailey and more like an accounting artifact with a real, but narrower, premium tucked inside it.
The Gap, In One Line
| Market | Typical value / median list | Days on market | Source and window |
|---|---|---|---|
| Hailey | $780,999 (Zillow ZHVI) | 56 avg DOM on 57 active listings | Zillow 2026; Sun Valley MLS snapshot, July 19, 2026 |
| Ketchum | $1,262,430 (Zillow ZHVI) | — | Zillow 2026 |
| Sun Valley | $1,184,012 (Zillow ZHVI) | — | Zillow 2026 |
| Blaine County | $1.2M median sale, down 23.8% YoY | 63 | Redfin, October 2025 |
The county-wide number is the tell. When Blaine County's median dropped 23.8% year over year in October 2025 while individual town values held more steadily, the mix of what closed shifted more than what anything was worth. That is the first hint that the Hailey–Ketchum spread is doing something similar in miniature.
What The Median Is Actually Measuring
Ketchum's inventory is heavy on resort-core condos, ski-adjacent townhomes, and larger mountain homes. Hailey's inventory is a working mix: historic in-town homes near Main Street, mid-sized single-family houses on standard lots in subdivisions like Woodside, Northridge, Della View, and Copper Ranch, plus a growing share of townhomes and cottages. When two markets sell different products, comparing their medians is like comparing the average check at a steakhouse to the average check at a bakery.
A few structural facts sharpen the picture:
- Blaine County's total taxable assessed value climbed 13.47% between the 2024 and 2025 assessment rolls, but the increases were uneven. Hailey rose 2.52%, Ketchum rose 13.84%, Sun Valley rose 17.61%, and unincorporated Blaine County rose 14.72%, according to the Blaine County Assessor. Hailey's slower assessment growth is not a sign of weakness. It is a sign that Hailey's stock was already priced closer to its underlying use value, with less resort-driven appreciation baked in.
- Hailey's average sold home sits around 1,887 square feet, well below the county average of 2,525. Smaller homes on smaller lots pull the median down without saying anything about condition or finish.
- The July 2026 Hailey snapshot showed active list prices ranging from $420,000 for a two-bedroom in Copper Ranch to $1,850,000 on Heroic Road in Northridge. That is a 4.4x spread inside a single town, which means the "median" describes almost no real house on the market.
The interpretive move for a buyer: stop comparing town medians and start comparing product categories across towns. A 3-bed, 2-bath, 1,900-square-foot single-family home in a walkable Hailey neighborhood is not the Ketchum median's competitor. It is competing with Warm Springs condos, Elkhorn townhomes, and older Ketchum in-town houses that share its footprint. Line those up and the gap narrows considerably.
The Supply Pipeline That's About To Move The Numbers
Hailey has more approved-but-unbuilt housing in the pipeline than any other Wood River Valley town, and the shape of that pipeline is going to change the median again over the next 24 months.
Sunbeam Subdivision sits east of downtown Hailey in the foothills, with Phase I sold out and Phase II under construction. Phase II availability and pricing are scheduled to release in summer 2026. The community is built around a nine-acre park, includes fiber to each lot, and is the first National Green Building Standards applicant in Idaho, according to the developer. New-construction inventory of that size, at that finish level, in Hailey rather than in the resort core, is the kind of stock that pulls the average sale price up while leaving the median softer for older homes.
Della Mountain Suites was approved unanimously by the Hailey City Council in early 2026. The three-building project at 1611 Aviation Drive in the Airport West Subdivision divides one lot into 12 mixed-use condo sublots, with 11 commercial units and one mixed-use unit including a second-floor accessory dwelling. Community Development Director Robyn Davis explained that the developer intends to sell shells that buyers finish out, and project manager Wilmot told the council he anticipates unit pricing in the $500,000 to $700,000 band, less without the ADU build-out. That is a new product category for Hailey, and one that pulls entry-level ownership toward the Airport Way Urban Renewal District.
At the same meeting, the council amended city code governing cottages and detached townhomes, expanding the legal shapes small homes can take on single sublots. Combined with the tiny-homes-on-wheels ordinance and the ADU rules the city passed in 2016, Hailey is quietly building the most flexible small-format housing code in the valley. The 60-unit Blaine Manor apartment community, developed by ARCH Community Housing Trust, is one visible result of that policy direction. More small-format inventory means more sub-$700,000 closings, which will push the reported median down even if per-square-foot prices hold steady or climb. Buyers who read that median as softness will misread the market.
The Friedman Variable
One reason Hailey's median stays discounted relative to Ketchum has nothing to do with the housing stock and everything to do with the runway that runs down the town's east side.
Friedman Memorial Airport, whose FAA identifier is SUN, is the third-busiest commercial service airport in Idaho and handles roughly 90,000 annual passenger enplanements alongside heavy charter and corporate-jet activity. It sits about one nautical mile southeast of downtown Hailey on land the Friedman family donated to the city in 1931. Homes on the east side of Hailey and along the Airport Way corridor trade at a durable discount to comparable homes north of town, and that discount is real. It is also priced in.
The variable worth watching is the airport's long-running relocation and tower-replacement story. The FAA declared the current 40-year-old control tower a hazard in 2013 because it sits inside a federally designated obstacle-free zone along Highway 75. On March 4, 2025, the Airport Authority Board voted unanimously in favor of a new tower, ultimately settling on an 80-foot design on the west side of the field, and the environmental review is underway with a public-comment window that ran through February 2026, according to KMVT and the Idaho Mountain Express. A separate, slower conversation about relocating the airport entirely to a new site remains on hold for environmental and cost reasons, per Friedman's 2020 system-plan summary. For a buyer, the takeaway is that meaningful noise or flight-pattern changes on a short horizon are unlikely. The Airport Way district itself, meanwhile, is being actively rebuilt around Della Mountain Suites and other mixed-use projects, which reframes what "airport-adjacent" means as an address.
What The Price Gap Actually Buys
Strip out the product mix, the small-format pipeline, and the airport discount, and the real Hailey–Ketchum spread on comparable homes narrows to something more like 15 to 25 percent, not the 40 percent the top-line medians suggest. That residual is the true premium for ski-lift proximity, walkable resort-core dining, and the shorter drive to River Run and Warm Springs.
For a buyer, the practical translation looks like this. A budget that buys a two-bedroom Ketchum condo with an HOA in the $600 to $900 monthly range will often buy a small single-family home with a yard in Woodside, Northridge, or the Della subdivisions. A budget that buys an older Ketchum in-town home near Fourth Street will often buy a newer, larger Hailey home with a garage, and put the difference toward the twelve-minute drive north when it matters. Neither is objectively better. They are different products at different price points, and the median obscures the trade rather than clarifying it.
FAQ
Is Hailey's market softening? The Redfin county-level figure showing a 23.8% year-over-year median decline in October 2025 reflects mix as much as price. Assessed values in Hailey still rose 2.52% on the 2025 roll per the Blaine County Assessor, and active list prices in July 2026 held above $780,000 across 57 listings. Read those signals together, not separately.
Will new supply from Sunbeam and the Airport Way projects push prices down? It will push the median down mechanically by adding smaller and newer units at accessible price points. That is different from pushing per-square-foot values down on existing homes, which is what most sellers care about.
Does airport noise actually affect resale? Proximity to Friedman is already priced into east-side and Airport Way inventory. The larger risk to model is not a change in flight patterns, which the FAA and the Friedman Memorial Airport Authority have signaled will be modest, but the pace of redevelopment inside the Airport Way Urban Renewal District, which is currently working in favor of nearby values.
