An adverse market delivery charge rate depends on the credit score of the borrower, the amount borrowed, and the loan-to-value (LTV) ratio. The LTV ratio is the ratio of amount borrowed to appraised value of the home. For example, a homebuyer who wishes to borrow $250,000 with a credit score of 730 and an LTV ratio of 80% will pay 0.5% (0.005) of $250,000 or $1250. The table below shows the adverse delivery charge for various credit scores and an LTV ratio of 80%. Answer parts (a) through (c).
