Walworth County

Walworth County, South Dakota sits at a median home price of $141,257 with a 4.09% year-over-year price gain, placing it in the 98th percentile nationally out of 1,000 counties ranked and second in South Dakota out of 50. The affordability index reads 100, the highest possible score, which tells you entry barriers here are about as low as you'll find anywhere in the country. The appreciation score of 83 is the standout metric in the profile, while the cash flow score registers zero and cap rate data is not available in the provided figures. That combination, high affordability and meaningful price appreciation against a cash flow story that doesn't pencil from the data available, tells you this is not a market where you buy the spreadsheet. You buy the trajectory.

The investor this market suits most is someone comfortable with a land-banking or buy-and-hold appreciation play at a very low basis. At $141,257 median purchase price, the capital at risk is minimal by almost any standard. A 20% down payment puts you in for roughly $28,251, and even modest rent collected against that equity base can represent a reasonable yield on invested capital if local rents support it. The zero cash flow score is a flag worth taking seriously, meaning this market likely does not generate meaningful positive monthly income at current price-to-rent ratios, but the appreciation thesis, 83 out of 100 and 4.09% trailing growth, does give a long-term holder something to work with. Value-add operators looking for distressed assets at scale will find thin deal volume in a county of 5,317 people. This is a single-asset or small-portfolio play, not a pipeline market.

Walworth County's economy is not detailed in the provided data, so no specific employers or anchors can be cited here. What the population figure does tell you is that this is a genuinely small rural market. At 5,317 residents, you are underwriting a very thin tenant pool. That is not automatically disqualifying, but it does mean vacancy in even a small portfolio can swing materially, and tenant turnover costs are harder to absorb when the replacement tenant universe is limited.

On carrying costs, the combined monthly tax and insurance estimate comes to $193, based on South Dakota's state-average effective property tax rate of 1.28% and an insurance rate of 0.36%. The tax flag here is "normal," meaning neither a headwind nor a tailwind relative to the national picture, though as the data source notes, the 1.28% figure is a state-average estimate and actual county or township rates in Walworth may differ. At a $141,257 purchase price, $1,808 in annual property tax and $509 in annual insurance are not burdensome in absolute dollar terms, and they leave room for the deal to work if gross rents are reasonable. The carry cost structure is one of the more investor-friendly aspects of this market, even if the income side of the ledger is uncertain.

The primary risks here are concentration and demographic. A county with 5,317 people has limited economic diversification by definition, and any softening in the local employment base or outmigration trend could suppress both rents and future appreciation. The stability score of 50 is the lowest metric in the profile and deserves weight. That score suggests this market's income fundamentals are not predictable in the way a larger metro or diversified economy would be. Investors who need consistent rent receipts to service debt should underwrite that instability score conservatively and stress-test their assumptions against extended vacancy.

Against its neighbors, Walworth is the most affordable county in this comparison by a significant margin. Marshall County comes in at $223,262 median with an equal overall score of 78, Beadle County at $188,792 with a score of 77, Perkins County at $164,641 with the highest neighboring score of 80, and Spink County at $162,012 with a score of 75. Hughes County, which includes Pierre, sits at $284,724 with a score of 75. Walworth's entry price is $23,000 lower than the next cheapest neighbor and less than half of Hughes County's median. If your thesis is lowest-basis appreciation in South Dakota with minimal downside capital exposure, Walworth wins that comparison on price alone. Perkins County scores slightly higher overall at 80 on a $164,641 median, which may be the sharper trade for an investor who wants modestly better stability metrics without giving up too much on affordability. Choose Walworth over its neighbors when capital preservation at the lowest possible entry point is the priority, and when you can accept thin near-term cash flow in exchange for that basis.
