Fil and I were talking last night, and neither of us really had a solid understanding of how mortgages work.

In doing some reading, I’ve already learned at least 10 things that I thought I understood but didn’t. Please fill in the comments with corrections, but this is how I think it all kinda works (not that I’ve ever had a mortgage):
