1. You mean that till all of 750K debt allocated for the "main house" (primary residence) is paid off, I don't begin paying off the 250K debt allocated for the rental ADU. Correct?
2. This means that, after the first year, every year the allocation of interest for the "main house" and ADU has to happen based on the principal balance calculated following the rule stated in 1 above.
My question boils down to - is the interest paid on principal borrowed for primary home a personal interest. Instead of 750K and 250 debt for primary and ADU, assume 900K and 300K. I start paying off 300K only after the 900K is paid off in entirety. Is that right?
