Ogle County

Ogle County posts an 8.44% year-over-year home price gain on a median purchase price of $238,006, which is the headline number that defines this market: it is an appreciation-first story, not a cash-flow story. The data provides no cap rate, no estimated cash flow, and no monthly rent figure for Ogle itself, which is a signal in its own right. When rent data is absent from a county this size (51,672 people), it typically reflects a thin rental market rather than a landlord's paradise. The appreciation score of 84 out of 100 confirms the price trajectory is real, but an affordability index of 79 and a stability score of 50 tell you the market is pricing in growth without yet earning consistent, predictable rental income to support it.

The investor this market suits is someone buying for long-term price appreciation and comfortable carrying a property that may run close to breakeven or slightly negative on a monthly basis. With a $238,006 purchase, a 20% down payment of $47,601, and a mortgage at 6.85%, your principal and interest alone is a meaningful carry before you add the next paragraph's numbers. This is not a market for a strict cash-flow buyer who needs to see a gross yield above 7% to pencil a deal. A value-add operator could potentially find opportunity here, given the combination of rising prices and a relatively affordable entry point by Illinois metro standards, but the absence of rent data in the county itself makes underwriting harder than it should be, and that uncertainty is a real risk, not a paperwork inconvenience.

The tax and insurance carry deserves its own line on your underwrite, and that is not an overstatement. Illinois carries a state-average effective property tax rate of 2.27%, flagged here as very high, which translates to $5,403 in annual property taxes on a $238,006 purchase. Combined with estimated annual insurance of $643, you are looking at $504 per month in tax and insurance alone before your mortgage payment, maintenance, vacancy, or management. That $504 figure is the single most important number in this data set for a buy-and-hold investor because it creates a high floor on the rent you need to collect just to cover carry costs. At 2.27%, Illinois ranks among the most punishing states for rental property investors, and Ogle County has no special exemption from that burden. The note accompanying this data is honest and worth repeating: this is a state-average estimate from Tax Foundation 2024, and actual county and township rates in Ogle may differ, so pull the county assessor's current levy rate before you close anything.

Compared to the neighboring counties in the data, Ogle's position becomes clearer. Williamson County to the south offers a median price of $152,606, a rent-to-price ratio of 0.0839, and the same overall score of 72. That gross yield is materially better for a cash-flow buyer, even accounting for its lower price point. Kankakee County comes in at $211,066 median with a rent-to-price ratio of 0.0744 and a matching overall score of 72, giving you a cheaper entry with visible rent data. Madison County at $187,237 and a 0.0702 ratio is the softest cash-flow option among the neighbors but still provides rent transparency that Ogle lacks. McHenry County at $349,331 is the premium option, with a rent-to-price ratio of 0.0726 and a higher price that puts it out of reach for many buyers working with a $47,000 down payment. Woodford County at $220,926 is priced close to Ogle with the same overall score of 72 but also lacks rent data here.

You choose Ogle over its neighbors when you believe in the appreciation trajectory, specifically that 8.44% annual price growth is durable, and when you can tolerate a thin rental market and an Illinois tax burden that will compress your cash-on-cash return. You choose a neighbor instead when your primary objective is yield visibility and monthly income. The stability score of 50 is the flag that warrants the most respect here: it sits at the midpoint of the scale, suggesting the market's price gains are not yet backed by the kind of deep employment base or demographic momentum that would make a long hold feel inevitable rather than speculative.
