What the numbers say
Resideline tracked 423 closed sales in Belleville over the last six months, with a median closing price of $184,667. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. These are the closings we track, not a complete county record, so treat the count as a large sample of the market rather than every sale that happened.

The Belleville angle
Belleville sits in the Illinois portion of the St. Louis metro and carries the low price level typical of that side of the river. Resideline tracked 423 closings there over six months at a median closing price of $184,667, or about 71 tracked closings a month. A median under $184,667 puts a 20 percent down payment at roughly $36,933, which is why the area draws attention from small landlords and first-time buyers. Scott Air Force Base nearby is a meaningful source of household stability in the wider county. Illinois property tax rates are high relative to the purchase price in this part of the state, so the monthly carrying cost on a Belleville home is heavier than the sale price alone suggests.
From market read to offer price
A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay.
