The Fannie Mae Standard Modification Interest Rate is subject to periodic adjustments based on an evaluation of prevailing market rates. The servicer must use the current Fannie Mae Standard Modification Interest Rate indicated below when evaluating a borrower for a conventional mortgage loan modification, excluding Fannie Mae HAMP Modifications. NOTE: As a reminder, the interest rate used to determine the final modification terms must be the same fixed interest rate that was used when determining eligibility for the Trial Period Plan and calculating the Trial Period Plan payment.
