The amount of SRP paid is based on the market value of the mortgage note, influenced by several key variables, such as interest rate, loan type, margin (for ARM loans), and the inclusion or exclusion of other items such as prepayment penalties. Also considered are the loan's LTV (loan to value), the borrower's credit score, the presence of private mortgage insurance (PMI), pre-payment risk of the borrower and other factors beyond the scope of this article.
