It can, provided the figures support it. The enterprise must be real and operating and must have the present or future capacity to produce more than a minimal living for Tobias and his family, which a fourteen-week season can achieve if net income across the full year is sufficient or if a credible plan shows it becoming so within about five years.
Marginality is answered with returns and payroll, not with enthusiasm
Start with what the seller has already filed. Several years of tax returns showing net income after the owner's own compensation is the strongest available evidence, because it describes the business as it actually performs rather than as a broker presents it. If the historical figures are thin, the question becomes whether the enterprise will get there, and that requires a plan with defensible assumptions: what changes under Tobias's ownership, why revenue would grow, and when.
