Platte County Assessor. The Assessor's Property Search, run on the Beacon system, shows owner and value information, including estimated values for the 2027 reassessment.

Platte County Collector. The Collector's annual tax sale list is published in The Landmark newspaper for three weeks before the sale.

How property is sold here
Platte County follows Missouri's rules, with its own calendar and offices. Read the Missouri guide for how the state works.
Tax sales
Missouri tax sales sell a certificate of purchase, which works like a lien: the owner can still redeem, and if not, the buyer can later apply for a Collector's Deed. The Platte County Collector holds the sale once a year in late August (Monday, August 24, 2026, at 10 a.m.), continuing day to day until every parcel is offered, and buyers must be present to bid. The list runs for three weeks in The Landmark newspaper ahead of the sale, and about 90 parcels were listed in 2026.
Foreclosure sales
Most Missouri mortgage foreclosures are trustee sales held outside court at the county courthouse in Platte City after notice in a local newspaper. Court-ordered sales are carried out by the Platte County Sheriff's Office.
Assessed values
The Platte County Assessor revalues real property every two years as Missouri law requires, and the next countywide reassessment takes effect in 2027.
Transfer tax
Missouri has no real estate transfer tax, and Kansas City and Platte County do not add one.
Worth knowing
Platte County covers the western part of Kansas City's Northland, north of the Missouri River, including the area around Kansas City International Airport, along with Parkville, Riverside and Platte City; most of Kansas City is in Jackson County.
Worth knowing
For the 2027 reassessment the Assessor projected just under 13,000 parcels would rise more than 15% and need a physical inspection, and about 8,000 would go down.
Worth knowing
The Platte County government website blocks automated visitors, so investors may need to open county pages in a regular browser.
