There _ we got that out of the way! OK. Now let's look at when to use a Letter of Intent vs. a Purchase Offer. I am specifically going to address this when looking at buying an apartment building or commercial real estate. The standard contract used when purchasing real estate is called a Purchase Offer, or a Purchase and Sale Agreement. You probably used this to buy your own house or condo.
Many a time, especially in a case involving a supposed seller who is either a fake seller or does not actually have the supposed crude in hand yet, or, an unscrupulous aspiring seller's agent or broker who actually has not acquired a crude supplier (seller) yet, buyers may issue an LOI only to find out that there is no seller on the other end. This happens a lot in situations where you have an hungry agent or facilitator who is still struggling to get a real supplier, and by extracting this LOI from an unsuspecting buyer, this facilitator can commit the buyer only for him then to start hustling to find a seller or supplier.
