If a requirement for private mortgage insurance is not otherwise canceled or terminated in accordance with subsection (a) or (b), in no case may such a requirement be imposed on residential mortgage transactions beyond the first day of the month immediately following the date that is the midpoint of the amortization period of the loan if the mortgagor is current on the payments required by the terms of the mortgage.
If a mortgagor and mortgagee (or holder of the mortgage) agree to a modification of the terms or conditions of a loan pursuant to a residential mortgage transaction, the cancellation date, termination date, or final termination shall be recalculated to reflect the modified terms and conditions of such loan.
Not later than 45 days after the termination or cancellation of a private mortgage insurance requirement under this section, all unearned premiums for private mortgage insurance shall be returned to the mortgagor by the servicer.
Not later than 30 days after notification by the servicer of termination or cancellation of private mortgage insurance under this chapter with respect to a mortgagor, a mortgage insurer that is in possession of any unearned premiums of that mortgagor shall transfer to the servicer of the subject mortgage an amount equal to the amount of the unearned premiums for repayment in accordance with paragraph (1).
A private mortgage insurance requirement in connection with a residential mortgage transaction described in paragraph (1) shall terminate in accordance with subsection (c).
Nothing in this subsection may be construed to require a residential mortgage or residential mortgage transaction described in paragraph (1)(A) to be purchased by the Federal National Mortgage Association or the Federal Home Loan Mortgage Corporation.
The cancellation or termination under this section of the private mortgage insurance of a mortgagor shall not affect the rights of any mortgagee, servicer, or mortgage insurer to enforce any obligation of such mortgagor for premium payments accrued prior to the date on which such cancellation or termination occurred.
