The most common forms are white phosphorus, made up of phosphorus atoms arranged like a tetrahedron (a four-sided pyramid), and red phosphorus, a solid but non-crystalline form of the element. Less common is black phosphorus, which is made of atoms arranged in a ring structure and looks a bit like the graphite at the point of a pencil.
How Mortgages Work. The origination fee is how lenders make money up front on your mortgage loan. Origination fees are calculated as a percentage of the total loan, usually between 0.5 and 1 percent on U.S. mortgages [source: Investopedia]. Going back to our APR example, let's say that the second lender charges a 3 percent origination fee, plus an application fee and other costs totaling $3,820 at closing.
The term origination fees refers to any expenses you pay to the lender to compensate him for providing the loan. Most lenders charge a basic origination fee equal to a certain percentage of the loan balance. Lenders may also include points in their origination fee, which are one-time prepaid interest payments you make in exchange for a lower annual rate. In most cases, you must pay these costs at settlement.
