Loudon County

Loudon County prices out at a median of $449,541 against median rent of $1,849, producing a gross rent-to-price ratio of 0.49%, or roughly a 3.21% cap rate on the model underwrite. At 6.85% financing with 20% down, the monthly mortgage alone is $2,357, estimated expenses add another $647, and gross rent covers none of that gap, producing a modeled cash-on-cash return of negative 13.41% and monthly cash flow of negative $1,155. Those numbers put Loudon squarely on the appreciation side of the spectrum. The appreciation score of 64 is the only metric in this dataset that earns a passing grade; the cash-flow score of 44 and affordability index of 36 confirm what the underwrite already shows. Year-over-year price growth of 1.43% is modest in absolute terms, so even the appreciation thesis here is a slow-build story, not a momentum play.

This market is not for the cash-flow buyer. The numbers above make that unambiguous. The investor this market suits is one who can absorb negative carry, has conviction that East Tennessee's growth corridor will continue to lift prices in smaller suburban counties adjacent to Knox County, and is underwriting to equity appreciation over a five-to-ten year hold rather than to monthly income. A value-add operator could move the needle somewhat by forcing rent above the $1,849 median, but even pushing rents to $2,200 or $2,300 on a renovated unit does not close a $1,155 monthly gap at these price levels. Anyone requiring day-one positive cash flow should look elsewhere before this county even makes the shortlist.

On carry costs, the combined tax and insurance load runs $401 per month, representing $4,810 annually against a gross rent stream of roughly $22,187. That is a meaningful slice of income before a mortgage payment is counted. The state-average effective property tax rate used here is 0.71%, which the Tax Foundation classifies as normal for Tennessee, and it is a genuine tailwind relative to high-tax states. That said, this is a state-average estimate and actual Loudon County or township assessments may differ, so pull the county assessor's data before finalizing any underwrite. Insurance runs 0.36% annually. Neither figure is punishing on its own, but together they represent 22% of gross rent, which matters when operating margin is already negative.

Loudon County ranks 617th out of 1,000 counties nationally, sitting at the 21st percentile overall and 69th out of 95 Tennessee counties. That positioning reflects the fundamental tension: prices have risen to a level that assumes appreciation continues, but the rental market has not kept pace. Concentration risk here is real for a small county of 55,507 residents. A rental portfolio built in a county this size has limited exit liquidity and is more sensitive to any single large employer or demographic shift than an investment in a mid-size metro would be. No economic anchor data was provided, so job-base depth cannot be assessed from this dataset, but any serious buyer needs to independently verify what is actually driving housing demand in Loudon before committing capital.

Comparing Loudon to its neighbors, Hamilton County (Chattanooga) stands out immediately: median price of $347,463, median rent of $1,500, and a rent-to-price ratio of 0.518% versus Loudon's 0.494%. Hamilton's ratio is 5% better on that measure and the entry price is $100,000 lower, which alone transforms the mortgage payment. Maury County posts a 0.512% ratio at a $395,565 median, and Rutherford County comes in at 0.496% on a $412,432 median. Sumner County at 0.461% and a $436,405 median is actually worse than Loudon on the rent-to-price math. Stewart County at a $230,942 median is the outlier on price, though no rent data was provided. The investor who wants the best cash-flow proxy in this peer group should look at Hamilton County first; those who are specifically betting on Knox County suburban spillover and want direct Loudon exposure may have a thesis, but they should do so with clear eyes about the carry costs and the fact that four of the five neighbors offer comparable or better rent-to-price ratios at lower or similar price points.
