Lake County posts a gross rent-to-price ratio of 6.93%, which lands it on the better end of cash-flow territory for Indiana, though the full underwrite tells a more complicated story. At a 4.5% cap rate against a median purchase price of $246,598, the asset-level return is thin but not dismissible. The problem is financing: at 6.85% on a 20% down payment, the monthly mortgage runs $1,293, and once you stack $498 in estimated expenses on top, you are carrying $1,791 against $1,423 in median rent. That produces negative $367 in monthly cash flow and a cash-on-cash return of -7.76%. Home price appreciation clocked 1.45% year-over-year, which is below inflation and well below what you would need to offset the carry loss with equity growth. Lake County is not a market where the numbers pencil at today's rates without either significant below-market acquisition or a value-add component that pushes rents above the median.
That framing tells you who this market does and does not suit. A straight buy-and-hold buyer financing at market rates will be subsidizing this property every month, so a passive cash-flow buyer should look elsewhere or underwrite carefully for rent premiums above the $1,423 median. An appreciation buyer faces 1.45% YoY growth and an affordability index of 74, meaning the median household earns enough to support housing costs but there is no visible demand-driven price acceleration in the data. The operator who has the clearest path to positive returns is a value-add buyer: someone who can acquire below median, force rent above median, or reduce basis through distressed purchase. The cash-flow score of 69 out of 100 suggests the market structure is not hostile to cash flow, but you need to find the right asset, not just the right market.
The monthly tax and insurance burden adds up to $232, which the model includes in the $498 expense line. Indiana's state-average effective property tax rate is estimated at 0.85%, flagged as normal, so this is not a market where taxes alone are killing your returns. That note is worth keeping in context: 0.85% on a $246,598 asset produces roughly $2,096 annually or $175 per month in tax, and $690 annually in insurance adds another $58. At 0.85%, the tax load is manageable, but the honest caveat is that this is a state-average estimate and actual Lake County or township-level rates may differ, so pull the county assessor data before finalizing your underwrite.
Lake County's stability score of 50 out of 100 is the number that deserves the most attention in a risk review. At the bottom half of the scoring range, it signals meaningful volatility or concentration risk in the local economy or demographic profile. The county has a population of 497,682, which gives it scale, but size alone does not create stability. The data does not include a breakdown of economic anchors or employer concentration, so no specific claims can be made about the job base. What the stability score does tell you is that this market is more exposed to cyclical or structural downside than the median county in the dataset, and that should show up in your vacancy assumption and your exit cap rate assumption when you stress-test the deal.
Comparing Lake to its neighbors clarifies where it sits in the regional picture. Monroe County has a rent-to-price ratio of 7.46%, the highest in the peer group, at a median price of $303,732, making it structurally more cash-flow-friendly but at a higher entry cost. Marion County is the most direct competition for a Lake County allocation: lower median price at $226,825, a 7.23% rent-to-price ratio, and an overall score of 65 versus Lake's 64. On paper, Marion edges Lake on both price efficiency and rent yield. Allen County and Floyd County both run rent-to-price ratios below 5.8%, meaning they are worse on cash flow metrics and would be harder to underwrite to positive cash flow at the same financing terms. Hancock County prices out higher at $321,689 with a 6.26% ratio, making it the least cash-flow-oriented option in the group. Lake County makes sense over its neighbors when you can identify specific assets below the $246,598 median, believe in a local rent growth story not yet captured in the median, or are specifically targeting the northwest Indiana corridor for reasons the broader county-level data does not capture. Marion County is the one peer that should be in your comparison set every time you underwrite a Lake deal.

Lake County in Indiana scores 64/100, ranking #231 of 1,000 US counties (top 30%). At 20% down and current rates, a median-priced rental loses about $367/month; the 6.93% gross rent-to-price ratio doesn't survive debt service. The thesis here is appreciation, value-add, house hacking, or all-cash.
