4. On Offer acceptance there is either a contract generated or a pro forma invoice generated. Since the offer is binding once accepted, the offer if well enough detailed and advised can and often does take the place of the contract.* Customarily in Real Estate transactions the purchase offer itself is generally also the contract for purchase as well.

It is at these times that a letter of intent can be used to let the owner of the house know that a potential buyer exists and thus the process of buying and selling the house may begin.
