Asking, homes for sale

Almost everyone searches for the "average" price, and almost every published figure — including this one — is the median instead. The difference matters. A true average is dragged upward by a handful of very expensive sales, so in a metro with a few multi-million-dollar homes it can sit well above anything an ordinary buyer would ever pay. The median is simply the sale in the middle of the list, which is why it is the number that describes a normal home.

Homes currently on the market in Centralia, IL are asking a median of $140,000. Do not read the gap between that and $129,875 as a discount you can expect to negotiate. Those are two different sets of homes — one is what sold, the other is what has not sold yet — and asking prices skew high precisely because the homes priced too high are the ones still sitting there. The honest measure is what each home got against its own asking price, and in Centralia, IL that came to 90%.

Measured by size rather than by house, homes in Centralia, IL are selling for about $82 per square foot. That is the fairer comparison when you are weighing one neighborhood against another, or this year against last, because the typical price moves whenever the mix of what happens to sell shifts — a run of large houses lifts it without anything actually getting more expensive.

We are also not quoting a year-over-year change for Centralia, IL. That comparison is built on the same single window this page has just set aside, so it would carry the same problem while looking like a firmer number.
