Property title and valuation for any asset pledged, the loan agreement and drawdown records, bank statements for every account the money passed through, the purchase agreement and escrow terms, and receipts for equipment and inventory purchased.
An unbroken line from origin to enterprise
Hypothetical example: the couple draw on the line of credit, move the funds to a joint account, convert currency, transfer to a lawyer's trust account and then to escrow. Five steps, five documents, and the amounts must reconcile at each stage. Include the title and current valuation for the Coalhurst property, the credit agreement showing the borrower and the security, statements covering every account with the relevant transactions highlighted, the currency conversion record, the trust ledger and the escrow agreement.
Then document what the money bought: the purchase agreement, the asset list, invoices for equipment and inventory. Where any part of the funding came from a family member, that is a separate thread needing its own source evidence and a gift or loan document. Gaps here generate the longest delays.
