Any published processing arrangements are on the official page. This household's timetable is set by the payment schedule on the land sale and by whether the receivable can be converted sooner.
Price the options before revisiting the question
Read the official page for the process and for any timeline it states, and note the date. Then look at the household's own calendar, which here is a five-year payment schedule. Waiting for the instalments means waiting years; converting the receivable means finding a buyer and accepting a discount, which takes months and costs money; borrowing against it means a lender's own process and security requirements. Each option should be priced before the immigration question is revisited, because the answer determines whether there is a decision to be made this year at all. In the meantime, document the prior immigration history and confirm admissibility, since that work is useful whichever route the family eventually takes.
Hypothetical example: the owner of an indoor climbing gym expects a property sale to close after the stated program terms may be revised. The first review should create a dated decision record: official program terms, source-of-funds milestones, eligibility evidence, and the household's immovable deadlines. The sale agreement and lender discharge conditions settle when cash can be used; a valuation does not. Check the official material again immediately before any payment, because a saved copy establishes only what was said on its own date. The common error is starting a costly sale process before confirming that the applicant can meet the separate immigration requirements. Work in that order: current official terms, personal eligibility and admissibility, usable liquidity, then payment planning. This process is not a conventional visa route, so comparisons by label alone are unreliable.
