Arnold, MO Housing Market 2026: Median Home Price, Last 12 Months

If you invest in or around Arnold, the number that matters is what homes actually close for, not what sellers are asking. Here is what Arnold sale prices look like right now, built from the closings Resideline tracked over the last 12 months, as of September 2026.

The snapshot

• •Closings tracked, last 12 months: 263
• •Median sold price, last 12 months: $289,900
• •Median sold $/sqft, last 12 months: $175
• •Middle half of sales closed between: $229,000 and $369,900

What the numbers say

Resideline tracked 263 closed sales in Arnold over the last 12 months, with a median closing price of $289,900. 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. The middle half of those sales closed between $229,000 and $369,900. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. 98% of the Arnold closings we track here are single-family houses, so these figures primarily reflect that segment, and the citywide $/sqft figure primarily reflects that segment as well. Across the 263 closings with usable living area, the middle half sold between $146 and $211 per square foot.

The Arnold angle

Arnold's last 12 months in our data: 263 tracked closings, a median closed sale price of $289,900, and a middle half of sales spanning $229,000 to $369,900, a spread close to typical for the markets we track. The band is not centered on its median, though; the stretch above the midpoint covers more ground than the stretch below, so upper-half outcomes in Arnold range further from the median than lower-half outcomes do. That asymmetry is the detail worth carrying into a valuation. A modest discount to the median is ordinary. A significant premium is possible, the band allows it, but it should be built from closed sales that resemble the property rather than inferred from the citywide figure.

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. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale, so it cannot be revised once the sale price is known. Grading it is a different matter in Missouri: because sale prices are not public record here, a confirmed closing price reaches us for only a small share of Missouri homes, and most Missouri estimates stay frozen and ungraded. The accuracy scoreboard is therefore a national record rather than a Missouri one. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Run any Arnold address through Resideline and you will see the local market and the property's value together, in one report.
