Separate loan agreements for each source, each stating the borrower, the security and personal liability; the escrow agreement showing funds are committed subject only to visa approval; and bank records tracing every contribution from the couple's accounts to the purchase.
Make the source, the security and the path each readable
The officer needs to see three things for each dollar: where it came from lawfully, whose risk it carries and where it went. For the home-equity line, provide the mortgage or credit agreement showing the couple as borrowers and their Kent property as security, plus statements showing the draw. For savings, provide statements covering the accumulation period and, if the money came from years of the greenhouse business, the tax returns that explain it. For any loan the U.S. bank secures against the nursery, provide the agreement so the officer can see exactly which portion is excluded rather than guessing. Then show the money moving: wire confirmations into escrow, the escrow agreement stating the funds release on E-2 approval and return if refused, and the purchase agreement's allocation of price among goodwill, equipment, inventory and any real property. A summary table reconciling every contribution to the purchase price saves the officer time and reduces follow-up questions.
Hypothetical example: a Canadian bicycle-frame repair owner wires a deposit to an escrow agent but cannot show the original source account because several transfers passed through a joint account. The first review reconstructs the trail with statements, wire confirmations, the escrow agreement and the purchase contract. Each transfer needs a clear explanation. A closing statement shows where money landed, while the earlier records show how the investor obtained and committed it.
