When a Mobile property needs a prior-date value, the report date stays current while the market analysis reaches back. Gross acreage can overstate utility when drainage, slope, or improvement placement limits use. The report date remains current while the effective date reaches back to the period the client needs analyzed.
The report is prepared now. Only the effective date of the value opinion reaches back. Keeping those dates separate makes the assignment easier to follow and prevents later information from being mistaken for evidence that existed in the earlier market. For Mobile, the appraisal should consider private infrastructure only when it changes the subject's competitive position.
On the earlier effective date, gross acreage can overstate utility when drainage, slope, or improvement placement limits use. Today's version of the neighborhood should not be projected backward if this condition changed after the effective date.
A prior-date assignment should establish what improvements, property rights, access, and site conditions existed on the effective date. Later physical changes may be documented, but they should not silently migrate into the earlier value.
Prior listings, permits, photographs, ownership records, and improvement history can help identify what should and should not be carried back to the earlier date. That documentation helps keep the current report transparent while supporting an earlier effective-date opinion.
