Polk County

Polk County posts a 6.31% year-over-year home price gain against a median purchase price of $260,727, which tells you immediately where this market sits on the spectrum: appreciation-led, with the scoring system confirming it at 90 out of 100 for appreciation and a cash flow score of zero. There are no cap rate or cash-on-cash figures in the data, which itself is a signal, since markets where those numbers are flattering enough to display tend to display them. With a 17,620-person county and an affordability index of 74, prices remain accessible relative to many Tennessee metros, but the rent base supporting those prices is thin enough that the model declines to estimate it. Investors underwriting this on a spread-over-debt basis at 6.85% should model conservatively and stress-test whether local rents cover PITI before committing.

This market suits an appreciation buyer far more than a cash-flow buyer or a value-add operator hunting yield. The 90 appreciation score and top-5 ranking among 95 Tennessee counties, combined with an 89th-percentile national rank out of 1,000 counties, indicate that price trajectory here is real and ranked. A buyer who wants to place capital in a county that is gaining value, accept neutral or slightly negative near-term cash flow, and harvest equity over a 5-to-10-year horizon has a data-supported case. A cash-flow operator looking to cover debt service and generate monthly income does not, at least not at a $260,727 purchase price and 6.85% financing.

No economic anchor or employer data was provided for Polk County, so this analysis will not speculate about the local job base or demand drivers. What the demographic data does confirm is a small, rural county of fewer than 18,000 residents. That scale matters: the rental pool is inherently limited, tenant turnover costs are amplified when vacancies take longer to fill in thin markets, and the path to appreciation is more likely driven by regional spillover and lifestyle demand than by organic employment growth within the county itself.

On carry costs, the combined monthly tax and insurance burden lands at $233, based on Tennessee's state-average effective property tax rate of 0.71% and an insurance estimate of 0.36%. That is a manageable figure that does not materially distort the underwrite the way high-tax states can. The property tax flag here is "normal," meaning the 0.71% rate is neither a meaningful tailwind nor a headwind compared to national peers. That said, the rate used is a state-average estimate per Tax Foundation 2024 data, and actual county or township assessments in Polk may differ, so pull the county assessor's current millage rate before finalizing your numbers.

The primary risks here are concentration and scale. A 17,620-person county with no displayed rental income data represents a thin market where even modest swings in demand, local employment, or migration patterns can move vacancy materially. The stability score of 50 is squarely median, which is the model's way of flagging that nothing about this county's economic base insulates it from regional or national downturns. Investors who rely on consistent rent collection to service debt should treat that 50 as a caution, not a green light.

Comparing Polk to its neighbors sharpens the decision. Claiborne County scores 74 overall versus Polk's 73, with a meaningfully lower median price of $228,611, which may offer a better entry point for investors who want similar appreciation exposure with less capital at risk. Rhea County and Lincoln County both score 68, making Polk the stronger pick on both overall score and appreciation trajectory if you are choosing among southeast Tennessee markets. Carroll County at 63 overall and $180,314 median is a different thesis, more affordable but lower ranked. Anderson County, the only neighbor with rent data, shows a median rent of $1,600 and a rent-to-price ratio of 0.064 at a $301,800 median, which is actually a more legible cash-flow picture despite the higher price, though its overall score of 62 trails Polk by 11 points. Choose Polk over its neighbors when appreciation is the primary return driver and you are not depending on the property to cash-flow from day one. Choose Claiborne if you want a comparable score at a $32,000 lower basis. Choose Anderson if you want visibility into the rent-to-price relationship before you buy.
