The Principal Limit Factor (PLF) is based in part on the age of the youngest borrower or Non-Borrowing Spouse, if applicable.
FHA released Version 2.4 of the HECM Calculation Software to accommodate the current PLF tables on September 19, 2017. The tables include PLFs for use where the Borrower has a Non-Borrowing Spouse younger than 62. The tables must be used for all FHA Case numbers assigned on or after October 2, 2017.
Lenders and counselors responsible for educating and informing prospective borrowers about FHA’s HECM program requirements must use the PLF table to calculate the Principal Limit. The Principal Limit Factor will be based in part on the age of the borrower or, if applicable, the age of an identified Non-Borrowing Spouse, whichever is younger.
