What Greenwood County's reading doesn't cover
Two lots a mile apart in Greenwood County can carry different soil, even though they share one countywide reading. A local geotechnical report, typically $1,000-$5,000 (around $2,700 typical), is the only way to know what one lot in Greenwood County will actually do.
What it costs to find out, versus to ignore it
