Friend of mine that's smart with money told me a 'trick' that I thought was worth sharing here for everyone that has a mortgage and the means - make a mortgage payment every 28 days.
If you think about it, that's actually more than just paying your mortgage every month as 365 days / 28 days = 13 payments.
That means you would be paying one extra payment every year which can save you tons in the long run. I think he said something like paying off his 20 year mortgage 5 years faster, or something like that. Anyways I thought this was clever enough to be actually doable more many without breaking the bank and a way to save a lot of money in the long run.
