Liberty, MO: what's different here
Liberty is the county seat of Clay County, just north of Kansas City, and is about 16 miles and roughly 19 minutes by car from Kansas City via I-35 N. The city has a mix of early- to late-century homes and newer construction, with an average home price around $366,000. Liberty's climate brings average summer highs of 88°F, winter lows of 17°F, and about 38 inches of snow a year, while local clay soils swell and shrink with rainfall, which can affect buried pipes and foundations.
