On the house note thing- I pay bi-weekly, and I added a little more on top of it. Say you have a payment of 1000. Instead of paying it once a month on a 30-year note, see if you can get into a 15-year note, with bi-weekly payments. Then, your payment should drop a little. So, we'll say 465 every two weeks. Add on the 35 extra, that's an extra 70 a month. Apply that to principal, and see your final house note in around 8 years.
I wish there were more places that would agree to weekly payments. Take that 465 every two, divide in half, and you get 232.50. Knock it up to 250, and that's an extra 17.50 a week, or 70 a month, for an extra 140 off your principal each month. Over the course of a year, you've put an additional 140x 12 months, plus two whole payments of 1000, for a grand total of 3680 in principal. Remember that interest is constantly declining as the principal balance decreases, and you save thousands of dollars, sometimes tens of thousands, over the lifetime of your mortgage. Going weekly could possibly save you 50% of your total interest or more. Not too shabby, and you haven't spent a dime more than that monthly grand you were going to be stuck with for 30 years, except now you pay off your house in 6-7 years!
Edit: Incidentally, that method works for car notes as well- I've been overpaying on my truck note for 8 months, and recently lost some income from Ike. Since I had a spotless (over)payment record, my truck note was able to be put off for a month, giving us the extra little cushion that we needed, and I'm STILL up by two payments!
The mortgage company would not work with us to move ONE payment to the end of the loan, so I am going to cheat them out of interest money by accelerating my mortgage payments on them, and I'll also try to go weekly for even more gain. That one payment that they refused to work with us on, and earn interest on, will cost them dearly now. Revenge can be sweet, especially when you use their own rules against them!
