Assume a gap. Job searching, hiring timelines and confirming status evidence all take time after admission, and the enterprise itself may not pay the investor early on. Hold living costs for that period in reserves outside the invested capital, so no one is tempted to draw down the business to cover rent.
Fund the gap before it opens
Estimate several months of housing, transport, insurance and schooling, and identify which account covers them. Separately, list the preparation costs — legal work, corporate formation, translations, travel — and confirm current government charges at the time each filing or appointment happens rather than budgeting from a figure quoted earlier. Ask any adviser to state in writing whether dependent applications and post-arrival status questions are inside the quoted scope or billed separately.
Hypothetical example: a couple purchasing a courier and last-mile delivery business assumes the second partner will be earning within six weeks of arrival, and budgets accordingly. A first review would test that assumption against three separate intervals: how long until the status evidence is in hand, how long a job search takes in that field and location, and how long from acceptance to first payday. Added together they routinely exceed the estimate, and the shortfall is met from somewhere.
Deciding now that it will not be met from the invested capital is what keeps the business case intact.
