La Salle County presents a low-entry-price but unproven-rent thesis. Zillow’s June 2026 median home value was $115,477, down 12.91% year over year, while market rent is not published; gross yield and a price-to-rent conclusion therefore cannot be computed. This is a screening case for an investor who can verify property-level rents and flood exposure, not a rent-led case. FHFA annual HPI is not published, and no metro context is supplied, so county evidence cannot be treated as metro evidence.
Housing economics show why the low basis is not enough. HUD’s two-bedroom Fair Market Rent is $1,015 per month, but it is a payment standard, not asking rent, and cannot substitute for market rent. The effective property-tax rate is 1.47%, with median annual tax of $1,434. Those costs must be tested against actual lease revenue and operating costs; missing market rent prevents even a gross, pre-cost yield screen. Review the falling value and tax burden together, not as proof of a bargain.
Demand evidence is mixed and small-county specific. Population is 6,839; net migration was negative 21, and average income per moving household was $40,483 for in-movers versus $106,380 for out-movers, with a supplied AGI gap of -$65,897. That pattern cautions on resident demand but does not identify tenants or explain household decisions. QCEW’s 2025 annual covered-employment measure rose 3.28%, while the covered-worker average weekly wage fell 1.04% to $1,612. Natural resources and mining represented 51.22% of disclosed private-supersector employment, showing concentration rather than the whole economy. There were 27 purchase mortgages and a 0% non-occupant share: limited investor competition evidence, not proof of weak buyer demand.
Risk limits are material. The modeled climate-loss ratio is 0.11% of building value per year, with inland flood the dominant hazard; this is not a property-specific insurance quote or dollar loss. Realtor.com MLS inventory figures are absent, so asking-price, active-supply, marketing-time, price-reduction, and pending evidence cannot test competition or liquidity. Next checks are property-level rent, comparable leases, taxes, insurance, flood maps, and the missing MLS and FHFA observations. Until then, this supports cautious screening, not a complete operating or resale underwrite.
