Puffing is an exaggeration of a fact.
Many agents are guilty of puffing when showing a house.
We have all heard agents say, "MAN! This is enormous," where they're not quite lying, but close. Who knows, maybe it is the biggest house the agent has ever seen-but more than likely the agent is exaggerating to create a sale.
Puffing is usually a exaggeration made by a salesperson or found in an ad regarding the quality of the item or the service offered.
It is more of an opinion than a fact, which is why it is usually not considered binding. Puffing is legal as long as the statements are not fraudulent. It's not lying, but it's close.
