I can't buy a house because the loan has not been approved. This situation is actually very common in the process of buying a house in the United States. In general, it is recommended to add some terms to the quotation. If you can't buy a house for some reason (for example, the loan is not approved), the contract will be terminated automatically, so there is no question of breach of contract.

I hope I can help you, and I hope to adopt it!
