A documented arm's-length sale is a helpful anchor for the lawful-source history, but questions about how the land was originally acquired, whether it was jointly owned, and how proceeds were divided still need answers. Prepare an investor-specific eligibility sheet covering lawful capital placed at risk, applicable amount and project location, job methodology, and management participation. Eligibility is proved elsewhere and by the investor personally: the lawful source and path of the capital, capital placed at risk in a new commercial enterprise, the job creation the law requires, and engagement at least at the level of policy formulation. Gifted capital is acceptable provided the gift is genuine and unconditional and the donors' funds are shown to be lawfully obtained, with the same documentary depth expected of the investor's own money. Where the slowest asset would delay filing beyond a point the household cares about, ask counsel what could be done differently: a smaller initial commitment where the structure permits it, a different funding source, or simply a later date.
