Not the part that will be the family's home. Capital counts when it is committed to the commercial enterprise, so property used in the business can be included while a residence bought in the same transaction is a personal asset and should be excluded from the figure.
Draw the line through the deed before an officer does
Rural acquisitions bundle a business and a house into one price because that is how rural property is sold, and the immigration analysis then has to take the bundle apart. The safest approach is to do the separation openly and early, with an allocation the seller signs and, where the amounts are significant, a valuation from someone independent. Hypothetical example: a buyer near Saint-Joachim-de-Shefford pays a single sum for a barn, an arena, forty acres and a four-bedroom house the family will occupy, and presents the whole figure as the investment.
An officer who values the residence at a third of the price is not rejecting the case out of hostility; the number simply is not what was claimed. Two related points save trouble later. Substantiality is judged in proportion to the cost of the business, so shrinking the numerator by removing the house also shrinks the denominator if the house was in it, and the ratio may hold better than expected.
And costs outside the purchase, such as legal fees, professional advice and the visa process itself, are expenses of getting there rather than capital placed in the enterprise.
