Work back from opening day and allow the funds to be committed first, since an application filed before the money is genuinely at risk is premature. Escrow conditioned solely on visa issuance is the usual way to reconcile commitment with commercial prudence.
Commitment has to come before the application, not after it
The sequencing problem is real and catches careful buyers. The classification wants the capital already irrevocably committed, while ordinary business sense resists transferring a purchase price before anyone knows whether the family can be admitted to run the business. The accepted reconciliation is an escrow arrangement that is irrevocable except for a condition tied to visa issuance, so the money is committed in substance while the deal remains commercially sane.
Around that, a seasonal purchase has its own calendar. Property inspections, licensing transfers, insurance and staffing all have to be arranged before an opening date that will not move, and a resort bought in March for a May opening leaves no margin for a request for further evidence. Dermot and Saoirse should also decide early who will be present when: the investor developing and directing the enterprise is expected to be there doing it, and an application resting on a manager they intend to hire later is a weaker one.
