This might be a dumb question...paying extra per month...

[Steve DellaPelle]

If my PITI Mortgage is ~2750k/month and I pay an extra $250/month so ~3000k total...is that $250 going straight to principal or does it get

split between principal and interest?

@Steve DellaPelle, it CAN get 100% allocated to your principal, but you'd need to advise the Bank EVERY time that the EXTRA $250 is "principal-only". Get Receipts from them, accordingly. What that'll mean is, yes, the principal goes down that extra $250/m, but, at the same time you are NOT getting ahead of your commitment to still pay $2,750/m, in case you thought you could just start adding up how much you were getting ahead, and just not pay that amount at your choosing. No, but, if you DON'T say "principal-only", it gets amortized at the same proportions as the rest of the payment, BUT, you'd start getting ahead of your REQUIREMENT to pay $2,750/m, until you're not ahead anymore. 

Get what I mean? If that was clear as mud, I'll have another go at explaining, later. Not a dumb question. Cheers...
