Choose and vet the project first, then sell with the subscription deadline in view. Selling first leaves cash sitting while the source-of-funds file is built, and a project's escrow terms determine when the capital must actually move.
Let the subscription terms set the sale calendar
Regional-centre offerings usually require the capital in escrow or in the enterprise's account by a subscription deadline, and some release funds to the project on filing rather than approval. The couple should read those terms before listing houses, because they fix when the cash must be liquid. The source-of-funds documentation can and should be assembled while the properties are still owned, since most of it concerns their history rather than their sale.
Then the sales can be timed to close shortly before the subscription deadline, with the mortgage discharges and closing statements completing the trail. Filing Form I-526E follows the investment. Keep the children's ages in view throughout, because a filing delayed by a slow closing can cost a near-21 child his eligibility.
After filing, expect a wait for adjudication and then consular processing; the family stays in Canada, keeps working, and does not make U.S. living arrangements until the visas issue. Hypothetical example: A specialty-aquaculture supplier intends to sell equipment and real estate before joining a regional-centre project.
The first review should create a dated source-of-funds file before any closing, preserving purchase records, tax filings, loan documents and sale papers in chronological order. Those records settle lawful source and path more reliably than a retrospective summary. The family must also plan for the conditional-residence stage and the later request to remove conditions, which depends on sustained investment and job-creation evidence.
A subscription deadline is a commercial deadline, not a reason to file before the transaction trail is ready or before a near-21 child is assessed.
