The Powderhorn and Willowbrook complexes along Gunbarrel Avenue and White Rock Circle are one of the closest things Boulder has to an entry-level condo market: 1980s two-bedroom units with a 2025–26 median of $409K, less than half the Boulder median. They are also one of the more competitive pockets in the county — sellers here list about 3.5% below market value, sell at 99.4% of asking in 38 days, and fewer than one listing in twelve is still available after two months.

The neighborhood

This sub-market is the cluster of condominium and townhome complexes on the east side of Gunbarrel, between Gunbarrel Avenue, White Rock Circle and the Boulder County open space that fronts Gunbarrel Commons park. Gunbarrel itself grew up around the IBM plant in the 1960s and filled in with subdivisions through the 1980s and 90s; it sits a couple of miles northeast of Boulder across a band of farmland, and it is split between the city limits and unincorporated Boulder County, a line that has been debated for decades without resolution. The complexes here are largely on the county side, which in practice means county road maintenance and the Gunbarrel Public Improvement District rather than city services.

The housing stock is unusually uniform. Powderhorn was built in the 1980s as two- and three-story wood-frame buildings with wood-burning fireplaces, a pool, hot tub, tennis courts and a fitness trail on shared green space; Willowbrook and the neighboring Willow Springs, Hunter Creek, Huntington Point and Habitat associations are of the same vintage and jointly fund the Commons park. The typical unit that sold in 2025–26 is a 2-bedroom, 2-bath, 1,030 sq ft condo built around 1984; nothing here predates 1950 and nothing was built after 2000. The one-in-ten sales that are detached houses are on the edges of the assessor area, in the $900K–$1.1M range, and price like the rest of Gunbarrel rather than like the condos.

Amenities are Gunbarrel's: the King Soopers center and the Gunbarrel brewery district anchored by Avery Brewing, Celestial Seasonings on Sleepytime Drive, Twin Lakes open space and the LoBo Trail toward Boulder Reservoir, and walking or short-bike distance to the office parks that employ much of the area. Schools are Heatherwood Elementary, Nevin Platt Middle and Boulder High. Transit is thin — RTD Route 205 and the BOLT — so most owners drive the Diagonal. Turnover is steady at 30–55 sales a year, nearly all condos, which makes this one of the most liquid condo markets in the county.

Homes and prices in Gunbarrel – Powderhorn / Willowbrook condos

Nine in ten sales are condos and townhomes, so the blended numbers here are condo numbers: a 2025–26 median of $409K, with the middle half of sales between $370K and $529K. That is 57% below Boulder's median and, at $408 per square foot against Boulder's $552, about a quarter cheaper per foot — the discount for a 1980s frame building on the county side of the Diagonal. The handful of detached houses sold each year run around $1M and are not what this sub-market is about; too few closed in 2025–26 to publish a house median.

The typical home sold in 2025–26 has 2 bedrooms, 2 baths and 1,030 sq ft, on a 6,836 sq ft lot; the median build year is 1984, with 0.0% of homes built before 1950 and 0.0% since 2000. Prices run from $280K to $1.14M.

Medians move with the mix of what sold each year (a run of large rebuilds lifts the house number); a bar is omitted when fewer than three of that type sold. Read the trend, not single-year steps.

What it takes to buy here

At the 2025–26 median of $409,000, a conventional purchase with 20% down at a 6.76% 30-year rate costs about $2,431 a month including taxes and insurance, which lenders would typically want to see backed by a household income near $104,192 and roughly $89,980 in cash at closing. 13.8% of all Boulder sales in 2025–26 closed below this neighborhood's median.

Who is buying in Gunbarrel – Powderhorn / Willowbrook condos

Buyers here are Boulder's workforce rather than its wealth. Health care is the largest sector at 14% (Boulder 12%), the university and research labs are at 13% (in line with the city), and tech is under-represented at 12% against 16% city-wide. What stands out is who is over-represented: food and beverage employers at 6% are more than twice their Boulder share, and retail, aerospace and media buyers all index above the city — the mix you would expect for a $400K condo a bike ride from the brewery district and the Gunbarrel office parks. Cash buyers are 23%, slightly above Boulder's 21%, in a price tier where investors and downsizers can write a check.

How Gunbarrel – Powderhorn / Willowbrook condos prices — and how to play it

B   Ownify competitiveness index 69 / 100 — a B, which in Boulder means homes with these characteristics in this sub-market are expected to sell at or above asking more often than most of the city. The index is driven by low asking prices relative to value and fast, reliable sales, not by bidding wars: fewer than one sale in five closes over asking.

If you are selling

The convention here is the opposite of the rest of Boulder: sellers list about 3.5% below market value (96.5%) and then close at 99.4% of asking, so the sale lands almost exactly at value (100.1%). Ownify's Boulder model puts the probability of selling in the listing at 91% for an ask at the convention, 88% at 108% of value and 86% at 112% — a shallow curve, so the cost of asking more is measured in days rather than in odds: Boulder listings at or under 105% of value sell in a median 38 days, those at 110–120% take 49.

Because 93% of the asking price passes through to the sale price in Boulder, the under-priced convention is leaving money on the table for the typical seller; only 17.5% of sales here close over asking, so the discount is rarely bid back. Price at market value or a point or two above, and expect to sell in five to six weeks with little give-back.

If you are buying

Buyers get less leverage here than the sale-to-ask ratio suggests. 55% of units sell under asking, but the median discount is well under 1% and only 7.5% of listings are still available after 60 days — the stale-listing pool that gives buyers room in Newlands or the foothills barely exists. Bid at or near asking on a well-priced unit and move quickly; the 23% cash share means a financed offer with a clean inspection timeline is competing against buyers who need neither. The upside is affordability: at the $400K condo median, this is well inside the Ownify Home Fund's $1M ceiling (2% down) — 96% of sales here since 2021 closed under $1M — and 2% down puts a buyer in for about $8,000 in cash versus roughly $90,000 for a conventional 20% down purchase. Check the HOA's reserve study and any special assessments before you bid — in a 1980s frame complex, that is where the real price difference between two similar units usually hides.
