I received a letter from my mortgage company earlier in the week that contained a fascinating proposal. If I were to take my monthly mortgage payment and pay half of it every two weeks, I could pay off my mortgage six years early, and save tens of thousands of dollars in interest.
By itself, this isn’t such a bad idea. The reason it works is that by paying every two weeks, you end up making 13 full mortgage payments a year, instead of 12. This accelerates your repayment of principal.
