Neither is chosen for being convenient. Identify why they differ — scope, condition assumptions, date, or a liquidation basis versus fair market value — and file the appraisal whose method matches an arm's-length sale of those units. Explain the second figure rather than hiding it.
Reconciling conflicting appraisals in the record
A dealer's trade-in quote prices a fast disposal; an independent appraiser prices an orderly sale. Ask both to state scope, inspection date and basis in writing, then submit a short reconciliation memo with the supporting invoices. Documents drafted in French need a full certified English translation for USCIS; consular requirements can differ, so confirm the language rules for the office actually handling the case.
A gap between two valuations is not inherently a problem; an unexplained gap is what invites additional scrutiny, since the adjudicator has no way to know which figure reflects the asset's actual worth. Once a reconciled figure is settled, use that same figure consistently across every later document referencing the asset, including the offer, the closing statement and any bank or brokerage record, so the file does not contradict itself in a place nobody thought to check. Keep both original appraisals in the file rather than only the one that supports the chosen figure, since a reviewer who later finds the discarded valuation elsewhere will want to know why it was left out.
