Ozarks lots were platted around new reservoirs
Bagnell Dam gave Missouri a lake with 1,150 miles of shoreline, and Table Rock Dam, finished in 1958, gave it another. Land companies platted the ground behind that shoreline into small recreational lots through the 1960s and 70s and sold them nationally, often to buyers who never walked the parcel. What those lots are worth now tracks build-out rather than plat: a lot on a maintained road with utilities at the line, in a section where houses actually went up, is a different asset from an identically drawn lot in a section that stayed timber. The assessed value tells you very little about which one you own.
