Stillwater market analysis

Stillwater County posts a cash-flow score of 0 and a cap rate of 0, which is about as clear a signal as you'll get: at a $505,188 median price, the rent-to-price math does not pencil for income-oriented investors. The appreciation score of 82 and 9.3% year-over-year price growth tell the other side of that story. This is a market where equity accumulation is the thesis, not monthly spread. The affordability index of 28 out of 100 confirms that prices have moved well beyond what local income typically supports for purchase, which tends to compress yields further and redirect would-be buyers into rentals, though not at rents that yet justify the entry price at these interest rates.

The investor this market suits is one buying for long-term appreciation and land value, not one who needs the property to carry itself from month one. With a 20% down payment of roughly $101,000 at a 6.85% rate, the mortgage load alone on a $505,188 acquisition is substantial before a single expense is added. A value-add operator might find opportunity if they can acquire below median and force appreciation through renovation, but the underlying yield problem does not disappear with improvements when the rent-to-price ratio is this compressed. The appreciation buyer with a long hold horizon, low leverage, or a cash purchase is the natural fit here. Anyone underwriting to cash flow should redirect their capital.

The county's population of 8,978 makes Stillwater one of Montana's smaller markets, which carries real implications for rental demand depth. A thin tenant pool means vacancy episodes can be longer and more damaging to returns, and the absence of a large institutional employer base or university anchor means demand is not structurally backstopped the way it would be in a county seat with a regional hospital or government campus. No economic anchor data was provided for this county, so that layer of the demand story cannot be evaluated here.

On carry costs, the combined monthly tax and insurance load is $509, using the state-average effective property tax rate of 0.83% and an insurance rate of 0.38%. That 0.83% rate carries a "normal" flag relative to national peers, so it is not the underwriting hazard you would face in, say, Illinois or New Jersey, but $509 per month before maintenance, management, and vacancy reserve is still a meaningful drag on a property that is generating zero net cash flow at acquisition. That figure is based on Montana's state-average rate per Tax Foundation 2024 data, and the actual Stillwater County or township rate may differ, so pull the county assessor's records before finalizing your underwrite.

The concentration risk here is real and worth naming directly. A population under 9,000 with a median home price above $505,000 represents a market where a handful of buyers and sellers determine comps. Liquidity is thin in both directions: easy to get stuck holding if sentiment shifts, and harder to find qualified tenants at rents that support the asset value. Price appreciation at 9.3% year-over-year has been favorable, but markets this small can reverse quickly when migration trends shift or a major local employer contracts.

Compared to its neighbors, Stillwater's $505,188 median is the second-highest in the peer group, trailing only slightly by comparison to Carbon County at $486,506. The more instructive contrast is with Custer County at $230,529 or Treasure County at $202,948, both of which offer entry prices roughly half of Stillwater's and carry the same overall score of 55 to 56. If cash flow is the goal, Custer or Treasure deserve a hard look first, accepting that their appreciation upside is likely lower. Cascade County, the only neighbor with rent data available, shows a rent-to-price ratio of 4.84% at a $331,268 median, which is meaningfully better yield math than Stillwater at any plausible rent level. An investor should choose Stillwater over its neighbors only when the specific thesis is Montana land and lifestyle appreciation, the hold period is five-plus years, and the monthly carry can be absorbed without dependence on rental income to service the debt.

The Bottom Line

HoldStillwater is a neutral market.
