Summit County

Summit County prices in at a median of $984,774 with median rent of $3,337 per month, producing a gross rent-to-price ratio of 4.07%. The model cap rate comes in at 2.64%, and the cash-on-cash return on a 20% down purchase at 6.85% is negative 15.86%, with estimated monthly cash flow of negative $2,993. Those numbers place Summit firmly at the appreciation end of the spectrum, and even then, with home prices down 0.44% year-over-year and an overall score of 34 out of 100 (771st out of 1,000 counties nationally, 52nd out of 62 in Colorado), the appreciation thesis needs scrutiny. The affordability index sits at 2 out of 100, meaning almost no one who rents here can afford to buy here, which can sustain rental demand but also caps the renter pool by income.

This is not a cash-flow market in any conventional sense. A buyer acquiring at the median price with 20% down is absorbing nearly $3,000 per month in negative carry before vacancy or capex. The only investor profile for whom Summit makes structural sense is a buyer who plans to occupy or short-term rent the asset, has substantial capital to absorb ongoing losses, and is making a long-duration bet on mountain real estate scarcity. A value-add operator looking to force equity through renovation faces the same debt-service math, and a 2.64% cap rate leaves no margin for project risk. The cash-flow score of 31 and the appreciation score of 48 confirm what the raw numbers show: the market does not reward either strategy cleanly. An investor requiring income from day one should stop the analysis here.

Colorado's state-average effective property tax rate is estimated at 0.51%, which is low, and that rate qualifies as a genuine tailwind relative to most markets. Combined with insurance, the monthly tax-and-insurance load on a median-priced asset is approximately $689, which is meaningful but not the primary problem in the underwrite. The caveat is standard: this is a state-average estimate from Tax Foundation 2024 data, and actual Summit County or township rates may differ, so pull the county assessor data before finalizing any pro forma. The low flag on the property tax is one of the few favorable inputs in the stack.

The most direct risk in Summit is concentration. The county population is 30,955, which means the rental market is thin by any measure, and demand is heavily tied to ski and outdoor recreation tourism. A ski-dependent local economy is exposed to season length, snowpack variability, and travel spending cycles in ways that a diversified metro economy is not. No economic anchor data was provided for this county, so the depth and stability of the employment base cannot be assessed from this dataset, but a 30,955-person mountain resort county with a median home price just under $1 million is almost by definition a second-home and short-term rental market rather than a primary residence rental market. Regulatory risk around short-term rentals is therefore a material underwriting consideration, and any investor assuming STR income to make the numbers work should verify current and proposed licensing, caps, or permit restrictions at the county and municipal level before underwriting that revenue.

Comparing Summit to its neighbors clarifies the relative position. Grand County at $752,023 median and a 3.73% rent-to-price ratio is cheaper but produces an even worse yield ratio. Routt County at $1,086,367 median and 3.80% gross yield is more expensive and yields less. Denver County at $532,579 median and a 4.19% rent-to-price ratio outperforms Summit on yield with roughly half the entry cost, and its overall score of 37 versus Summit's 34 reflects that. Boulder County at $702,437 median and 4.21% rent-to-price ratio also beats Summit on both price and gross yield, scoring 37 overall. Jefferson County at $609,991 median and a 3.75% yield scores 38, the highest of the five neighbors. None of these comparables is a screaming cash-flow market, but Denver, Boulder, and Jefferson all offer better gross yield, lower entry prices, and higher overall scores than Summit. An investor should choose Summit over these neighbors only if they have a specific, defensible thesis around mountain resort appreciation or personal-use value that cannot be replicated in a Front Range county, and even then they should stress-test the negative carry at current rates against a multi-year hold before committing capital.
