Paydown

Pay down your mortgage early and you get to whine about other things.

Paydown usually refers to the process of early-paying the principal you owe on the mortgage you borrowed when you bought the lovely 2-story for $200k with the nice lawn and the basement bondage parlor. Your normal monthly payment is about $1,850, of which $450 is principal and $1,400 is interest. But in this case, you write a check for $2,000 every month, paying down an extra $150 each month, meaning that, each year, you have about $1,800 less in principal due...which in turn means you have less interest to pay. Things snowball, and instead of taking 30 years to pay off your home, you do it in like 12 or 17 years. Way less interest you'll have paid along the way. The banks are happy to get their principal back early as well. Your credit rating goes up and up. And everyone is happy.

Except maybe the neighbor whose bedroom window catches a lot of the noise from your basement.
