A commercial appraisal typically remains valid for 3 to 6 months, but this can vary depending on market conditions and the type of property.
Appraisers usually note the effective date of the appraisal, and lenders or buyers may require a new appraisal if the market changes significantly or if too much time has passed.
For example:
| Property Type | Typical Validity |
|---|---|
| Office/Industrial | 3–6 months |
| Retail | 3–6 months |
| Multi-family | 3–6 months |
| Special-use properties | 3 months or case-by-case |
If the market is very volatile, an appraisal might become outdated sooner. Lenders and investors often treat appraisals as a snapshot rather than a long-term guarantee.
