Can extra mortgage payments be made to lower the monthly payment amount?
Typically, this is not an option, as the monthly payments are fixed. It depends on the willingness of your financing bank for such a change. You probably will have to refinance (with them or another lender); which is not a bad thing, as you even can get a lower interest rate potentially (as of Jan 2017 - this will change). Consider too: It could be a better solution to instead invest the 25000, and use the investment returns to fill up the difference every month. Certainly more effort, but you probably come out ahead financially.
