A subdivision that has received final plat approval but has not been developed physically, (i.e. utilities, streets, etc.), should be valued by comparable sales of similar subdivisions. However, undeveloped subdivisions should not be appraised for acquisition purposes by the use of the Developmental or Subdivision appraisal method, as these approaches may not provide credible results.

The lots within a subdivision that have been physically developed with their infrastructure in place should be appraised individually.
