Custer County

Custer County sits at a median home price of $254,092 with year-over-year appreciation of 7.79%, earning it a 94 appreciation score and a national ranking of 53rd out of 1,000 counties analyzed, placing it in the 93rd percentile nationally and 3rd in Montana. That appreciation trajectory is the headline here. The cash flow score, however, is 0, and the cap rate fields return zeroed values, which signals that this market does not pencil as a yield play at current pricing and financing conditions. With a 6.85% interest rate environment and a $254,092 purchase price requiring roughly $50,818 down, the math on monthly carry is tight before you even get to expenses. Custer is squarely on the appreciation end of the cash-flow-versus-appreciation spectrum, and investors should underwrite it that way rather than hoping to manufacture yield that the data does not support.

This market suits an appreciation-oriented buyer who is comfortable holding a property with neutral to negative monthly cash flow in exchange for price growth running near 8% annually. At an affordability index of 76, the market is not deeply cheap, but it is not the kind of inflated coastal market where appreciation buyers typically get burned on entry price either. A value-add operator looking to force equity through renovation could find opportunity here if they can source off-market deals below the $254,092 median, since the appreciation tailwind means any basis improvement compounds quickly. A pure cash-flow buyer, on the other hand, has no data here to support the thesis, and should look elsewhere unless they are bringing an unusually large down payment that reshapes the debt service picture.

The tax and insurance carry costs are worth putting on your spreadsheet explicitly. At the Montana state-average effective property tax rate of 0.83%, annual taxes on a $254,092 property run approximately $2,109. Insurance adds another $966 annually, using a state-average rate of 0.38%. Combined, those two line items total roughly $256 per month before mortgage, maintenance, vacancy reserve, or management. The 0.83% tax rate carries a "normal" flag, meaning it is neither a meaningful headwind nor tailwind relative to national norms. It will not save your deal, but it will not break it either. Keep in mind these figures are state-average estimates per Tax Foundation 2024 data, and actual Custer County or township-level rates may differ, so pull the county assessor's numbers before finalizing any underwrite.

Custer County's population of approximately 11,957 reflects a small, rural Montana market anchored in Miles City, the county seat. No economic anchor data was provided for this county, so specific employer analysis cannot be offered. What the population figure does tell you is that this is a thin rental market by volume: fewer potential tenants means longer vacancy periods if you misjudge the demand pool, and fewer comparable sales means appraisals can be unpredictable. A stability score of 50, sitting exactly at the midpoint, reinforces that picture. This is not a market with deep economic diversification or a large institutional rental base to backstop demand. Investors should size their vacancy reserves accordingly and not assume quick lease-up timelines.

The concentration risk is real in a county this size. With roughly 12,000 residents, a single large employer contracting or a demographic shift in the agricultural or energy sectors could move the local rental market materially. Regulatory risk data is not provided, so no claim can be made there. The 7.79% year-over-year price appreciation is compelling, but in small rural markets that number can reflect a handful of transactions rather than deep, sustained demand. Treat it as a positive signal, not a guarantee.

Compared to its neighbors, Custer is the most expensive market in this group at $254,092, edging out Pondera County at $250,371 and sitting well above Sheridan County at $165,002, McCone County at $230,436, Blaine County at $205,075, and Liberty County at $219,236. Despite carrying the highest price point, Custer holds a higher overall score (75) than Pondera (73), Blaine (71), and Liberty (71), and matches McCone (75) while trailing Sheridan (77) by two points. Sheridan County at $165,002 is the standout for investors prioritizing entry price and overall score: it offers the lowest basis in the group with the highest overall score. Choose Custer over its neighbors when your thesis is appreciation specifically and you want the price momentum that its 7.79% growth rate and 94 appreciation score reflect, and when you can carry a property that does not generate meaningful cash flow. If yield or lower entry basis matters more, Sheridan County deserves a closer look before you commit capital here.
