On a $400,000 purchase in Mason County, WV, property tax comes to about $2,172 a year — roughly $181 a month — at this county's effective rate of 0.54%.
$
Effective rate 0.54% = this county's median owner-occupied tax bill ($727, ACS 2022 5-year estimate) divided by the typical home value at the time ($133,987, 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.
