Carroll County

Carroll County scores a 94 out of 100 on appreciation and lands in the 98th percentile nationally across 1,000 counties, ranking 4th among 99 Iowa counties. That appreciation score, paired with a 7.54% year-over-year price gain and a median home price of $215,880, tells you where this market sits on the spectrum: it is an appreciation-first market, not a cash-flow engine. The data provided shows zeroed-out cap rate, cash-on-cash return, and estimated cash flow fields, which indicates that at current prices and a 6.85% rate, the numbers do not pencil to a meaningful cash-flow position out of the box. The affordability index of 84 and median price under $220,000 do keep entry costs low relative to most appreciation-oriented markets, but the missing margin comes from rent levels that have not kept pace with price appreciation, not from an expensive purchase.

This market suits an appreciation-oriented buyer who can carry the asset without relying on monthly spread, or a value-add operator who can force equity through renovation and refinance rather than counting on day-one yield. The 7.54% price appreciation is the primary return mechanism here. For a pure cash-flow buyer running a 20% down payment, the $43,176 down payment buys into a market where the carry costs alone, before vacancy or maintenance, consume a meaningful share of rent. The stability score of 50 out of 100 also suggests this is not a set-and-forget, low-volatility hold, which makes it less suited to conservative cash-flow buyers who want predictability over growth.

Turning to carry costs, the tax and insurance picture deserves a dedicated line on your underwrite. Iowa's state-average effective property tax rate is 1.53%, which the Tax Foundation flags as high, and the data corroborates that with an annual property tax estimate of $3,303 on this median-priced asset. Combined with $734 in annual insurance, you are looking at $336 per month in tax and insurance alone before mortgage, maintenance, property management, or vacancy. At a 6.85% rate on an $172,704 loan (80% of purchase), the mortgage payment adds further weight. These carry costs are the central reason cash flow is absent at current prices. The 1.53% rate is a state-average estimate and actual Carroll County or township rates may run higher or lower, so pull the county assessor's data before finalizing your model.

The population of 20,728 is the key risk factor to size correctly. Carroll County is a small, rural Iowa market, and small population bases create concentration risk: a single employer contraction, a demographic shift, or even a modest increase in housing supply can move vacancy and rents materially. No economic anchor data was provided, so this analysis cannot speak to employer diversity or job base stability beyond what the stability score of 50 already signals. That score, sitting at the midpoint, suggests neither a highly resilient nor a highly fragile economy, but in a county this size, the margin for error on economic disruption is thinner than in a large metro.

Against its neighbors, Carroll County carries the highest median home price in the comparison set, at $215,880, compared to Harrison County at $212,859, Louisa at $169,860, Fremont at $166,833, Humboldt at $153,359, and Hardin at $139,169. All five neighbors share overall scores of 77 or 78, while Carroll scores 78 as well, so the differentiation is not in overall score but in the appreciation sub-score of 94, which is Carroll's standout figure. If your thesis is appreciation capture and you are willing to pay up to the highest price point in the peer group, Carroll is the pick. If you need cash flow and can accept slower appreciation, Hardin or Humboldt offer entry points $62,000 to $77,000 cheaper, which meaningfully changes the debt service math at the same interest rate. Choose Carroll when price appreciation is the primary return driver and you have the balance sheet to carry a low-yield asset through its growth cycle.
