Small-place caveat: the Census publishes these figures for Waterman from a five-year rolling sample, and with about 1,419 residents that sample is small. The median home value here carries a much wider margin of error than a big-city figure does, so treat it as indicative rather than exact. The DeKalb County figures are drawn from a far larger sample if you want a steadier number.
