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 origination fee is how the lender makes money on the front end of the transaction. On average, home buyers pay 1% of the loan amount in the form of an origination fee. For example, on a loan of $300,000, a 1% origination fee would come out to $3,000. So the more money you borrow, the higher the fee. If your lender is charging you a mortgage origination fee much higher than 1%, you should ask them why.
