On a $400,000 purchase in Wapello County, IA, property tax comes to about $6,480 a year — roughly $540 a month — at this county's effective rate of 1.62%.
$
Effective rate 1.62% = this county's median owner-occupied tax bill ($1,837, ACS 2022 5-year estimate) divided by the typical home value at the time ($113,391, Zillow, 2022-12-31). Exemptions the seller holds — homestead, senior, veteran — usually do not transfer with the deed, so a new purchase can run above this figure. The county assessor sets the assessed value; this is an estimate, not a quote.
