Illinois presents a compelling split investment story. Chicago is a deep, liquid market with strong appreciation — statewide values are up +5.2% YoY, outpacing most comparable Midwest markets — but carries one of the highest effective property tax rates in the country at 2.08%. Every Illinois deal begins and ends with a precise property tax calculation. Downstate is where the yield lives — and its numbers read like vitals, meaningful together rather than alone: Peoria's ~11.2× GRM, an estimated cap rate approaching 8%, and a 45% expense ratio combine into one of the strongest yield opportunities in the entire Midwest. One more discipline item: Chicago's RLTO imposes specific landlord requirements — consult an Illinois attorney before purchasing there. Statewide averages — $260,000 homes, $1,450/mo rents, 14.9× GRM — mask just how differently the two halves of this state behave.

Long-term rental markets

Peoria is the headline — homes near $128,000 renting around $950/mo (11.2× GRM), anchored by OSF HealthCare and UnityPoint. Rockford matches the entry price ($128,000, $925/mo, 11.5× GRM) on manufacturing and healthcare employment. Chicago ($295,000, $1,650/mo, 14.9× GRM) is the deepest market in the state and its major employment center, and Champaign ($218,000, $1,150/mo, 15.8× GRM) rides University of Illinois campus rental velocity and demand.

Short-term rental markets

Illinois STR is regional-getaway demand: Galena is the boutique standout ($285,000, ~$245/night at 65% occupancy), Starved Rock ($225,000, ~$195/night) serves the state-park crowd, Springfield ($155,000, ~$145/night) draws Lincoln tourism and government events, and Chain O' Lakes ($325,000, ~$155/night) is the northern lake district. In getaway markets like these, themed properties and standout amenities often tip the choice when guests compare listings side by side. All carry moderate STR regulation — verify local rules before closing.

Up-and-coming markets

Decatur ($115,000) is the highest-cash-flow emerging entry, anchored by ADM's headquarters. Normal ($215,000) pairs Illinois State University with a growing corporate corridor in a balanced market, while Joliet ($285,000) brings a major logistics employment base and Elgin ($318,000) offers the affordable Chicago-metro entry point.

The bottom line for physician investors

Illinois lets you choose between Chicago-grade depth and Peoria-grade yield — some of the strongest cash-flow arithmetic in the Midwest — as long as the 2.08% property tax is the first number in every analysis and an attorney reviews anything inside Chicago's RLTO. The +5.2% statewide appreciation means the downstate yield plays are no longer purely cash-flow bets: the rent checks and the equity line are moving in the same direction.
