I think you may be referring to 1026.41(d)(2) & (3).
How is the required monthly PMI payment not included in the escrow account? It may be a direct passthrough payment but it still processes through the escrow account.
Escrow account means any account that a servicer establishes or controls on behalf of a borrower to pay taxes, insurance premiums (including flood insurance), or other charges with respect to a federally related mortgage loan, including charges that the borrower and servicer have voluntarily agreed that the servicer should collect and pay. The definition encompasses any account established for this purpose, including a “trust accountâ€, “reserve accountâ€, “impound accountâ€, or other term in different localities. An “escrow account†includes any arrangement where the servicer adds a portion of the borrower's payments to principal and subsequently deducts from principal the disbursements for escrow account items. For purposes of this section, the term “escrow account†excludes any account that is under the borrower's total control.
