Regarding #1 - Again, because they used the word "lapsed" in the FIL, I am going to assume (until otherwise clarified via another FIL) that they meant lapsed, so this means that the Bank can charge premiums incurred during the 15 day period after a policy has lapsed and the 46th day when the FP policy was obtained by the Bank. So, if it is a Bank's practice to FP on the 46th day and make the effective date of the FP policy the day after a borrower's policy has EXPIRED, they cannot charge the premium for 30 days worth of coverage - only 15 days. Correct?
Regarding #2 - There are three parts to your answer I want to address.
First, it is your opinion then that a Bank can FP at any time (and I am not talking about when the effective date is per se - I am saying the actual day in which the Bank can obtain or request a FP policy from their vendor) - they do not have to wait until 45 days after the notice was sent to the borrower?
Second, if the borrower does not pay within 30 days of expiration to renew the policy - it lapses (which is the scenario I am talking about - a borrower that simply does not pay to renew at all). If the Bank orders a FP policy and requests an effective date which is 31 days after the policy expired, then the property will not have had coverage for 30 days. The Bank is not going to be covered. Let's say a borrower's policy expired on 1/1 and the policy lapsed on 1/31 because they didn't pay the premium to renew - they went on vacation on 1/15 for two weeks and unbeknownst to them, Hurricane Dan comes through and the house it engulfed in flood waters while they were sipping Mai Tai's on the beach in Malibu. When they return home, they and the Bank are not going to be covered. UNLESS, when the Bank obtained their FP policy, they requested an effective date which was the day after the borrowers policy expired (which all the vendors I know of allow the Bank to do - it was just that prior to the BW amendment, the Bank could not charge the borrower for premiums incurred during the 45 day waiting period after the notce was sent).
Finally, I agree that the Bank can only charge permiums for the 15 days between when the policy lapses and the 46th day (since they used the word "lapsed" in the FIL). So the Bank is still stuck with 30 days of premiums if they obtain FP policies with effective dates back to the day after the borrower policy expires.
