bussiness report question

Q. 3.            Mary believes that the ten percent required down payment will protect the bank from a loss of principal.   However, should the loan default, the funds are likely to be tied up, without interest income for six to nine months.  The funds could have been used to fund a prime loan at around six percent interest with a default rate of well under one percent.  Mary is wondering whether or not the two percent premium paid on the performing loans will cover the expected loss from the nonperforming loans.  She expects a potential default rate around 3-5 percent.   The average home loan is about $200,000.

Q. 4.            Mary wants to sell some of these subprime loans on the developing secondary market.  However, she also wants the bank to retain some in their asset portfolio to add income and make the stockholders happy.  She wants an evaluation of the associated risks and a recommendation on whether or not to hold or sell.  What are the possible gains and losses to the bank after December 2006?
