Gallatin County

Gallatin County sits at the extreme low end of the Illinois price spectrum, with a median home price of $79,377, but the investment data raises an immediate flag: the cash flow score registers at 0, and the cap rate, cash-on-cash return, and estimated monthly cash flow are all listed as zero. That is not a rounding artifact, it is the model's signal that the rent-to-price math here does not produce a viable return at current inputs. The appreciation story is equally thin, with a score of 12 out of 100 and home prices already declining 6.4% year over year. This is a market where affordability is maxed out at 100, meaning prices are low by any standard, but low prices alone do not make a market investable if the income side of the equation fails to keep pace.

The investor profile for Gallatin is narrow. This is not a cash-flow market, not an appreciation market, and not a conventional buy-and-hold destination based on these numbers. The overall score of 50 and a national percentile ranking of 23rd out of 1,000 counties tells you this sits in the bottom quarter nationally. A value-add operator looking to manufacture equity through rehab might find the sub-$80,000 price point useful as a low absolute-dollar entry, but only if local rents can be pushed high enough to clear expenses, which the current data does not support. A capital-appreciation buyer has no case to make here given the negative year-over-year price movement. If any buyer profile fits, it would be a deeply contrarian, cash-purchase operator willing to absorb carry costs with no leverage and no expectation of near-term appreciation, which is a very specific and high-tolerance mandate.

No economic anchors or employer data were provided for this county, so the demand-side story cannot be told with any specificity. What the population figure does reveal is the scale of the market: 4,967 residents. At that size, Gallatin is micro-market territory, where a single employer closing, a school consolidation, or a demographic shift can move vacancy and rents in ways that are impossible to predict from county-level aggregates. The stability score of 50 reflects this uncertainty without overstating it.

The tax and insurance picture is one of the most material factors in the underwrite here, and it cuts against the market. Illinois carries a state-average effective property tax rate of 2.27%, flagged as very high, which translates to $1,802 in annual property taxes on a $79,377 purchase. Combined with $214 in annual insurance, the combined monthly tax-and-insurance load comes to $168. On a property at this price point, that $168 per month is not a minor line item, it is likely a significant share of gross rent, and it is the reason cash flow scores zero even at a price this low. Worth noting: the 2.27% figure is a state-average estimate from the Tax Foundation and actual Gallatin County or township rates may differ, but Illinois county rates frequently exceed the state average in smaller jurisdictions, so underwriting at or above this rate is the prudent starting point. Before any offer, pull the actual assessed value and tax bill for the specific parcel.

The concentration and demographic risk here is real and data-supported. A county of under 5,000 people with declining home prices and no identified economic anchors carries meaningful demand risk. A rental portfolio of even two or three units represents a non-trivial share of the local market. Tenant turnover, vacancy, or a population decline could make units difficult to re-lease at any rent that covers costs. These are not invented concerns, they follow directly from the population figure and the price trend.

Compared to the neighboring counties provided, Gallatin's case weakens further. Greene County, at a median home price of $106,001 and an overall score of 65, offers a higher score for only $26,000 more in median purchase price. DuPage County scores 66 with a rent-to-price ratio of 0.587% monthly, and Monroe County at 0.470% monthly provides at least quantifiable rent income against price. Gallatin provides neither a rent-to-price ratio nor a demonstrated rent level in the data. An investor choosing between these markets should look to Greene County if budget is constrained, given the 15-point overall score advantage at a price point still well below $120,000. Gallatin's only numerical advantage over its neighbors is the lowest median price in the comparison set, and that advantage disappears the moment you account for Illinois' very high property tax rate applied against even a small rental income stream.
