The 30% mark is the federal threshold for cost burden, so anything above it signals a stretched rental market.

Keystone CDP, CO in context
How this area compares with national benchmarks.
Keystone CDP is a small town in Colorado, with 1,111 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #213 of 482 ranked by population — larger than 55% of them. The median age here is 30.1 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.
Households in Keystone CDP earn a median of $51,369 a year, 34.6% below the national figure of $78,538 and 41% below the $86,484 median for the 223 Colorado cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 39.2% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.
The typical owner-occupied home in Keystone CDP is valued at $1,264,500, 316.8% above the national figure and 179% above the $453,600 peer median, while median gross rent runs $861 a month, 38.8% below the national figure, or roughly $10,332 across a full year. A household on the local median income would put about 20.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 24.6×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 20.8% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
Home values sit at 24.6× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.
No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
