Kelso, WA Housing Market 2026: Median Home Price, Last 12 Months

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

The snapshot

• •Closings tracked, last 12 months: 209
• •Median sold price, last 12 months: $336,000
• •Median sold $/sqft, last 12 months: $253
• •Middle half of sales closed between: $264,892 and $424,000

What the numbers say

Resideline tracked 209 closed sales in Kelso over the last 12 months, with a median closing price of $336,000. 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 $264,892 and $424,000. 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. 86% of the Kelso 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 209 closings with usable living area, the middle half sold between $189 and $292 per square foot.

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, rehab cost estimator, BRRRR 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 and graded against the real closing price after it sells. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

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