Yeah I figured you couldn't just pay ahead and skip a month or two on payments. A buddy of mine was telling me about taking out a line of credit and using that towards mortgage payments. He said a personal line of credit not a heloc. Of course that would have to be analyzed since the interest would be higher than the mortgage but it would speed up the amortization rate and lower the interest.
Like take this example. Let's say a 100,000 mortgage at 4%. The amortization would be calculated at 71,870. So you're paying that much just in interest over the course of the loan. That's nearly the entire loan and that's with excellent credit. If I get a line of credit and throw 10,000 towards the mortgage it would erase s huge chunk of it. In fact, just doing regular payments, I would reach 90,000 in 2023, five whole years just to get 10k less. That's the problem with amortization. In fact, not until 2030 would I be paying more towards principal than interest. Ima research that more and it depends on the line of credit. But even at 8% interest, it's still cheaper than a 100,000 loan that the interest keeps accruing on a daily basis.

Now what I would do is throw the line of credit towards the loan, keep paying the mortgage and just pay down the line of credit with what's left over and rinse and repeat. Can shorten the length that way.
