Well it does help pay it off faster if you make that lump sum payment, then you take the extra amount you are saving each month and pay that towards the principal. Marrying the two ideas.
So you have now paid off a huge chunk of your principal, lowered your monthly payment while not paying thousands in closing costs, AND you are now able to throw even more money every month towards that same principal, therefore your loan amount decreases faster. Plus, if you take any work bonuses, tax refund (who is still lucky enough to get those? Amirite?), flip house profit (that you don’t use for a 1031 exchange), or lottery winnings (who gets that lucky?) and throw those at the principal as well as a recast (depending on how much they are) you are constantly decreasing the amount you owe.
So while yes, the loan term IS actually for 25-30 years over and over, they can’t hold you to making payments on it for that long just to keep paying interest. Once your payoff is paid, it’s paid.
I could win the lottery tomorrow (fat chance) and pay off my current mortgage WELL before that 30 years is up. Because I paid what I actually owe. Doing a recast just helps you save mo way every month to be able to afford it.
And the good thing is that if you do that, you have a lower payment and less chance of losing your house if something terrible happens to your life.
