1. The % deductible applies to the total points paid for all your mortgages. It doesn't matter if you only paid points on loan B.
2. You can use the daily balances for loan A and divide by the number of days or you can use the beginning balance on Jan 1 and the ending balance on 04 Jun. Both of these do not include the day the loan was paid off and you must have equal payments at least monthly.
3. Correct. Remember to use the ending balances according to your statements from the lender for loans B and C.
4. It is my understanding that you do not take into account payments made on Jan 1, 2025.
