Stanley County

Stanley County, South Dakota presents a genuinely thin data set for rental underwriting, and that itself is a signal. The cash flow score is 0 and both cap rate and cash-on-cash return are listed as zero, meaning the model cannot generate a reliable rent estimate for this market. That is not a rounding artifact; it reflects how illiquid and sparsely traded this rental market is. With a population of 2,979, Stanley is one of the smallest counties in the dataset, ranking 402nd out of 1,000 nationally (49th percentile) and 30th out of 50 South Dakota counties. The median home price sits at $309,334, up just 1.1% year over year, and the appreciation score of 61 suggests modest but not compelling price growth. Without a usable rent-to-price ratio or cap rate, this county effectively cannot be underwritten as a traditional income property on current numbers alone.

That scoring profile tells you exactly who this market does and does not suit. A cash-flow buyer has no path forward here; the model returns a zero cash flow score and zero cap rate, and there is no rent data to build from. An appreciation buyer sees a 61 appreciation score and 1.1% trailing price growth, neither of which justifies paying $309,334 in a county of under 3,000 people when comparable South Dakota counties trade at $160,000 to $215,000. A value-add operator might find opportunity if they have direct market knowledge and can verify local rents independently, but the affordability index of 64 and the population constraint mean your exit options, whether sale or refinance, will be limited by a thin buyer pool. This is a market where you need boots-on-the-ground intelligence that no model can substitute for.

No economic anchor data was provided for Stanley County, so employer-specific demand drivers cannot be assessed here. What the population figure alone communicates is that rental demand, even if present, is highly concentrated. A single employer contraction or an outmigration of a few hundred residents would materially shift vacancy dynamics in a county this small. Stability scores at 50, the midpoint of the range, which is consistent with that concentration risk. Investors accustomed to markets with diversified employment bases and depth of renter demand should price in the uncertainty that comes with a sub-3,000 population county.

On carry costs, the state-average property tax rate of 1.28% is flagged as normal, meaning it is neither a tailwind nor a particular headwind, but at a $309,334 purchase price it still produces $3,959 in annual property taxes. Combined with $1,114 in estimated annual insurance, you are carrying $423 per month in tax and insurance before mortgage, maintenance, or management. At a 20% down payment ($61,867) and 6.85% on the remaining $247,467, the mortgage payment alone is substantial. Because no rent estimate is available in this dataset, you cannot close the loop on whether gross rent covers those fixed costs, let alone generates income. That gap in the underwrite is the most important number in this analysis: you are being asked to carry $423 per month in tax and insurance, plus a mortgage, in a market where no rent benchmark exists to validate the trade. Use the state-average rate as a starting point only; actual county and township rates in South Dakota can differ, and you should pull the Stanley County assessor data before finalizing any underwrite.

The comparative picture reinforces the caution. Every neighboring county except Brookings trades at a significantly lower price point: Corson at $159,475, Miner at $182,594, Hutchinson at $213,908, and Edmunds at $214,525, all with overall scores of 57 to 62. Brookings County is the one neighbor with a rent data point, showing a $1,447 median rent against a $307,689 median price, a rent-to-price ratio of 0.0564%, and an overall score of 62. Brookings scores higher than Stanley (62 versus 59), offers a nearly identical price point, has actual rent data to underwrite against, and carries a larger population base that implies greater rental demand and liquidity. If you are considering deploying capital in this part of South Dakota, Brookings is the analytically defensible choice over Stanley at current prices. The lower-priced counties (Corson, Miner, Hutchinson, Edmunds) may offer better entry points for appreciation buyers willing to accept similar or better overall scores. Stanley makes sense only if you have a specific deal, a specific tenant situation, or local knowledge that the public data cannot capture.
