What is the cheapest city to buy a house in Illinois?

Galesburg, with a median closed price of $110,000 over its reporting window, among Illinois cities where Resideline tracked at least 100 closings inside the city limits.

Are these asking prices or sale prices?

Closed sale prices. Every price median is the price homes actually closed at inside the municipal boundary, not a listing price. The one column measured differently is realized appreciation, which uses the postal city, as the note under the table says.

Why does a cheap city show a high price per square foot?

Because the ranking median covers every property type that closed, condos and multi-family included, while the $/sqft column is single-family houses only. In cities where most sales are condos, the median price is low and the house $/sqft can still be high.

Is the appreciation figure a forecast?

No. It is the median annual change between consecutive sales of the same home, on repeat-sale pairs. It is historical and nominal, and it says what happened, not what will.

Cheapest Cities to Buy a House in Illinois (2026)

Ranked cheapest first by median closed price, this list covers Illinois cities with at least 100 tracked closings inside the city line. A low entry price only means something next to the per-square-foot figure, the realized appreciation and the time to contract, so those sit in the same table.

How to read this list

A low median is where the analysis starts, not where it ends. Property type, size, condition and block move a number far more than the city line does, so check any address on this list against its own comparable closings.

Figures last updated October 3, 2026 from closings Resideline tracked. Appreciation is the median annual change between consecutive sales of the same home; it is historical, nominal and not a projection.
