The point is that the often_heard notion and claims by some sellers or their overzealous agents and brokers that the use of the LOI to initiate a purchasing proposal by a buyer "is how it is usually done and this is how it should be," may be applicable and prudent only in the minds, the imagination, and hopes or dreams of those sellers, especially the more marginal ones and their brokers and agents who operate on the fringes largely on the Internet. It is NOT a view that is shared by the broad spectrum of credible buyers, more especially when the "sellers" involved are largely unknown and obscure operators.
Many individuals will use the terms Letter of Intent, Memorandum of Understanding, and Term Sheet interchangeably, however there are slight, mainly style, differences. Memorandum of Understanding (MOU): The main difference between the MOU and LOI is the nature of the signatories. While two parties are involved in a LOI, a MOU can involve more than two parties. Additionally, while a letter of intent needs only the party which proposes the agreement to be a signatory, a MOU implies that all the parties involved have to be signatories.
