Franklin County

Franklin County sits at a 3.5% cap rate with a gross rent-to-price ratio of 0.054, which places it firmly in appreciation territory rather than cash-flow territory. At a $315,281 median home price against $1,417 in monthly rent, the numbers simply do not pencil for immediate income: at 6.85% financing with 20% down, the modeled position is negative $732 per month cash-on-cash, translating to a -12.11% cash-on-cash return. That is not a rounding error or an underwriting technicality; it is a structural deficit at current rates and prices. Year-over-year home price growth of 2.49% is real but modest, and the appreciation score of 75 out of 100 is the single metric that actually moves in an investor's favor here. The overall score of 59 and a national percentile rank of 49 confirm this is a middle-of-the-pack market that doesn't stand out on either end.

Given those numbers, Franklin County is not a market for cash-flow buyers or anyone relying on the property to service its own debt at current rates. The investor this county suits is one betting on continued price appreciation in a smaller Tennessee market, who can absorb negative carry, has equity or liquidity to weather the monthly deficit, and expects either rate relief or rent growth to eventually close the gap. A value-add operator could theoretically improve the rent picture, but with a 0.054 rent-to-price ratio even a 15-20% rent increase after renovation leaves the fundamentals structurally challenged. The affordability index of 62 and affordability score of 62 suggest there is still some runway before the market becomes fully locked out, but the county ranks 35th out of 95 Tennessee counties, meaning roughly two-thirds of the state offers a more compelling entry point by this composite measure.

No economic anchor data was provided for Franklin County, so it would be speculative to characterize the employer base or rental demand drivers beyond what the numbers themselves imply. What can be observed is that a population of roughly 43,000 is a relatively thin renter pool, and small-market dynamics mean individual asset performance can diverge significantly from county medians. Stability scores of 50 suggest the market is not notably resilient to economic downturns, which matters for a buyer underwriting a long hold with negative early-year cash flow.

On carry costs, the combined monthly tax and insurance burden is $281, using a state-average effective property tax rate of 0.71% (Tax Foundation 2024 estimate) and an insurance rate of 0.36%. That $281 figure is baked into the $496 estimated monthly expenses and is not flagged as unusually high; the 0.71% rate sits in a normal range and is not a major drag on its own. That said, Tennessee county and township rates can differ from the state average, so confirming the actual Franklin County millage before closing is basic due diligence, not optional. At these rent levels, every $50 of additional monthly cost shifts the cash-on-cash return by roughly 100 basis points.

The meaningful risk here is the combination of thin cash flow, a small renter population, and no obvious economic anchor data to suggest structural rental demand growth. Concentration risk is real in a 43,000-person county: a single large employer relocating or contracting can meaningfully shift vacancy and rent levels, and without confirmed diversification of the local economy, an investor is underwriting more uncertainty than the modest 2.49% appreciation trend justifies on its own. Regulatory and demographic risks are not supported by the provided data, so those concerns should be investigated locally rather than assumed.

Against its neighbors, Franklin County is the second-most expensive market in this peer group after Fayette County at $366,798, but it delivers the weakest rent-to-price ratio at 0.054, well below Shelby County's 0.076, Madison County's 0.075, Fayette County's 0.064, and Haywood County's 0.073. Shelby and Madison counties both carry higher overall scores (61 and 60, respectively) and significantly better rent-to-price ratios at meaningfully lower price points. An investor who wants Tennessee exposure and cares about cash flow should look at Shelby or Madison first; both offer more rent per dollar of purchase price, lower absolute price points, and marginally better composite scores. The case for choosing Franklin over those neighbors is narrow: it comes down to a belief that Franklin's appreciation trajectory (score of 75, the highest in this group by implication) will outpace the rent-to-price disadvantage over a multi-year hold, and that the investor has the capital structure to carry a deficit in the meantime.
