Letters of intent may be advanced in the world of commercial real estate. In some specific domestic markets (for example in principal to principal deals between upstream Petroleum traders and producers in the same country, or certain Joint venture projects) they may be found. But there is no underlying and supported standard international application for the Letter of Intent.
Academic: In the academic world a letter of intent is known as a Statements of Purpose and is part of the application process. Real estate: Often times there are properties that are not listed on the MLS or with a realtor. 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.
