How long is an appraisal usually good for?

An equipment appraisal typically stays reliable for about six months to a year, though there's no single fixed expiration date, it depends on how quickly the market for that specific asset moves.

A machinery appraisal is a snapshot of fair market value as of a specific effective date, not a permanent number. Equipment in a stable market with limited technological change might hold its stated value for a year or more, while equipment in fast-depreciating or volatile categories (specialized medical devices, technology-driven manufacturing systems) can go stale within a few months. Most lenders, insurers, and courts want a report that reflects current conditions, so if significant time has passed since the effective date, or if the market, industry, or equipment's condition has shifted, they'll often ask for an updated valuation before relying on it.

The right window really comes down to intended use:

• SBA or equipment financing: lenders often want a report dated close to the loan application, since collateral value drives underwriting decisions.
• Insurance coverage: carriers may accept a report for a year or longer if equipment condition and market pricing haven't changed materially.
• Estate, tax, or litigation matters: the effective date usually needs to match a specific legal date (date of death, date of filing), so the report's "shelf life" matters less than its accuracy on that date.

If you're unsure whether an older appraisal will still hold up, it's worth checking with the party requesting it before assuming it's current.
