Mortgage fun

My mortgage is a standard 30-year fixed. I have the option to pay extra against the principal at any time, and I do so every month. I don't prepay a lot, but I do round my mortgage payment up to the nearest hundred. One of my favorite things is seeing my loan period drop by an extra month. That is, while I have 29 years and 1 month left in the 30-year period, I will have fully paid for my house after 28 years and 11 months. This month's extra payment finished off another month's worth of mortgage interest.

It's a small victory, I know, but it makes me happy. As my income increases, I do hope to increase my monthly prepayment further. As fun as it is to watch my mortgage figures every month, I definitely look forward to not having to make that payment. Maybe I'll finally win the lottery tonight.
