Knox County

Knox County sits at a gross rent-to-price ratio of 0.055, which translates to a 3.58% cap rate at the modeled purchase price of $376,337. That cap rate is below the 6.85% financing rate being used in the underwrite, which is why the model spits out negative $849 per month in cash flow and a cash-on-cash return of negative 11.77% on the $75,267 down payment. The price-to-rent dynamic here places Knox firmly on the appreciation side of the spectrum rather than the cash-flow side. Home prices grew 1.17% year-over-year, modest but positive, and the county scores a 62 on appreciation versus a 53 on cash flow. The affordability index of 49 signals that the market is increasingly stretched relative to local incomes, which is worth keeping in mind both as a constraint on further price growth and as a driver of rental demand from households priced out of ownership.

This market does not work for a buy-and-hold investor whose primary goal is day-one cash flow. The numbers are unambiguous on that point: negative $849 per month is not a rounding error or a light value-add problem, it is a structural feature of a market where cap rates have compressed well below the cost of debt capital. The investor this market suits is one with a longer time horizon who is underwriting to appreciation and equity buildup rather than monthly income, and who has the balance sheet to carry a negative cash flow position through a hold period. A value-add operator could potentially compress that gap by acquiring distressed assets below the $376,337 median and forcing rents above the $1,728 median, but the spread between cap rate and interest rate means the bar for making the numbers work is high regardless of strategy.

The $336 per month in combined property tax and insurance is a meaningful line in any underwrite here. Tennessee's state-average effective property tax rate is estimated at 0.71%, which the Tax Foundation flags as a normal rate, neither a tailwind nor a red flag, but at a $376,337 purchase price it still produces $2,672 annually in taxes alone. Insurance adds another $1,355 per year at the 0.36% modeled rate. Together those two fixed costs consume $336 of monthly gross rent before debt service, vacancy, maintenance, or management. Investors should treat these as floor estimates; actual county and township rates in Knox may differ from the state average, so pulling the specific parcel-level tax bill for any acquisition target is worth the ten minutes it takes.

Knox County ranks 47th out of 95 Tennessee counties in overall investment score, sitting at the 50th percentile nationally. That positioning is not a condemnation, but it does mean there is no particular edge to extracting here relative to a typical US market. The county's stability score of 50 suggests average resilience to demand shocks, which combined with the negative carry makes the risk-adjusted case harder to build unless an investor has specific local knowledge, a defined exit to an owner-occupant buyer at higher prices, or access to off-market assets at meaningful discounts to the median.

Comparing Knox to its neighbors sharpens the trade-off considerably. Washington County, at a median home price of $296,677, carries a rent-to-price ratio of 0.063, which is meaningfully better than Knox's 0.055, and its overall score is identical at 54. An investor trying to buy closer to cash-flow neutral in the same region of Tennessee has a real alternative there. Grundy County at $200,790 and Jackson County at $222,300 represent much lower entry points, though the data provided does not include rent or rent-to-price figures for either, so a direct cash-flow comparison is not possible. Van Buren County at $226,333 and Meigs County at $281,128 sit in a similar position. The case for choosing Knox over these neighbors comes down to one thing: if you believe Knoxville's population base of 481,406 and its urban amenity set support stronger long-term appreciation and a deeper tenant pool, you pay a premium for that in the form of a worse cap rate. If the goal is income today, Washington County's higher rent-to-price ratio at a 14% lower price point deserves a hard look before committing capital to Knox.
