sales with no house on the record yet
County record through July 28. Those 49 left-out sales are mostly builders buying lots, plus a few new houses the county hasn't added yet. Counting them would pull the median down, so we don't.
Why stop at July? Polk County's public sales lookup shows nothing after July 28 for any town. Axios reported in March that the Assessor's office was moving to a new vendor system. New sales go here as soon as the county posts them.

Quick answers
Grimes home sales: FAQ
What is the median home sale price in Grimes, Iowa?
On the Polk County side, the median sale of an existing house in 2026 is $330,000, across 142 sales through July 28. That leaves out new builds and sales with no house on the county record yet.
Why does Grimes have two sets of housing numbers?
Grimes sits in both Polk and Dallas counties, and each county publishes something different. Polk lists residential sales. The Dallas County file we use lists new-construction lot sales, so its prices are for land, not finished houses.
Why are the Polk County sales not newer?
The Polk County Assessor's public sales lookup shows nothing after July 28 for any town. Axios reported in March that the office was moving to a new vendor system. We will add sales as soon as the county posts them.
Do these numbers include new construction?
Not in the main median. New builds are shown on their own: 17 sales on the Polk side with a median of $426,464. Dallas County lot sales are land only.
