Final answer:
W should review the contract for extension clauses, negotiate with the seller to amend the contract, or possibly consult a lawyer to file for specific performance if legal grounds exist.
Step-by-step explanation:
If W wishes to force the seller to honor the contract and grant additional time to obtain financing, the best course of action would involve legal steps. It's important to review the original contract to see if it includes any provisions for extensions or contingencies related to financing, as these clauses could provide a legal basis for the request. In the absence of such a clause, W may need to negotiate with the seller to amend the contract. If the seller is unwilling, W could potentially seek legal recourse by filing a suit for specific performance based on breach of contract, assuming all other terms were met and the financing clause was the only impediment. It would be advisable for W to consult with a lawyer specializing in contracts to explore all the available options.
