Cities to look at in Illinois

Chicago

$2,011/mo two-bedroom · $1,780 one-bedroom (Chicago-Joliet-Naperville, IL HUD Metro FMR Area)

Chicago is a genuinely great American city — world-class architecture, museums, food and transit, with lakefront summers that make the brutal winters worth it. Housing is cheap for its size, though property taxes and neighbourhood-level violence vary sharply.

Naperville

$2,011/mo two-bedroom · $1,780 one-bedroom (Chicago-Joliet-Naperville, IL HUD Metro FMR Area)

Naperville is an affluent western suburb of Chicago with top-rated schools, a riverwalk and a commuter train downtown. Safe, family-focused, expensive by Illinois standards, and thoroughly suburban.

Springfield

$1,237/mo two-bedroom · $977 one-bedroom (Springfield, IL MSA)

Springfield is Illinois's state capital and Lincoln's town — government employment, a low cost of living and a quiet central-Illinois pace. Flat, affordable, and short on big-city amenities.

Peoria

$1,212/mo two-bedroom · $961 one-bedroom (Peoria, IL MSA)

Peoria is a Illinois River city long defined by Caterpillar, with a medical school and a low cost of living. It has faced corporate downsizing, and the housing market is among the cheapest in the Midwest.

Champaign

$1,173/mo two-bedroom · $996 one-bedroom (Champaign-Urbana, IL HUD Metro FMR Area)

Champaign, with neighbouring Urbana, is the University of Illinois's town — a strong engineering and computing pipeline, cheap housing and a young population surrounded by prairie farmland.

Rockford

$1,172/mo two-bedroom · $896 one-bedroom (Rockford, IL MSA)

Rockford is a northern Illinois manufacturing city with aerospace suppliers and extremely low housing costs. It has struggled economically for decades, and Chicago is roughly ninety minutes away.

Bloomington-Normal

$1,287/mo two-bedroom · $996 one-bedroom (Bloomington, IL MSA)

Bloomington-Normal is a pair of central Illinois cities built around State Farm's headquarters and Illinois State University. Stable and affordable, with Rivian manufacturing nearby and flat farmland all around.

Decatur

$1,091/mo two-bedroom · $857 one-bedroom (Decatur, IL MSA)

Decatur is a central Illinois agribusiness and manufacturing city, home to ADM's North American operations. Very cheap housing, a shrinking population and a modest downtown.
