What is underwriting?
Underwriting is a process through which applicants are scrutinized for their risk when it comes to the financial security involved. Many people will encounter underwriting when they buy a home, a process during which their financial soundness and the value of the home are both carefully examined, sometimes repeatedly, until the bank is satisfied that they are likely to repay the loan.
The reason the home is also scrutinized is so that, just in case they're wrong, they know they can recoup a lot of money simply by selling the asset. Underwriting, then, isn't really for the customer, but it enables the customer to get what they need or want from a financial institution through a transparent process that is frequently reproduced for similar financial entanglements.
