Risk-based pricing
 |
Risk-based pricing is a methodology adopted by many lenders in the mortgage and financial services industries. It has been in use for many years as lenders try to measure loan risk in terms of interest rates and other fees. The interest rate on a loan is determined not only by the time value of money, but also by the lender's estimate of the probability that the borrower will default on the loan[1]. A borrower who the lender thinks is less likely to default will be offered a better (lower) interest rate. This means that different borrowers will pay different rates.
The lender may consider a variety of factors in assessing the probability of default. These factors might be characteristics of the individual borrower, like the borrower's credit score or employment status. These factors might also be characteristics of the loan; for example, a mortgage lender might offer different rates to the same borrower, depending on whether that borrower wished to buy a single-family house or a condominium.
Risk factors
Credit score and history, property use, property type, loan amount, loan purpose, income, and asset amounts, as well as documentation levels, property location, and others, are common risk based factors currently used. Lenders 'price' loans according to these individual factors and their multiple derivatives. Each derivative either positively or negatively affects the cost of an interest rate. For example, lower credit scores equal higher interest rates and vice-versa; typically, those who provide less verifiable income documentation due to self-employment benefits will qualify for a higher interest rate than a someone who fully documents all reported income. Mortgage and other financial service industries value credit score and history most when pricing mortgage interest rates.
