In my opinion, this is a bad idea. If you are able to make your mortgage payments, do so. I recently spoke with a person who quit making mortgage payments so that his mortgage company would consider him for a loan modification. They filled out all the papers as requested by the bank for the modification. After about four months of not receiving any payments, the bank started foreclosure proceedings. The debtors never opened their mail from the foreclosure attorney and ignored a certified letter that was sent to their residence. As a result, there house was foreclosed and there is nothing they can do to get it back. Chapter 13 does not lower your future mortgage payment but it can wipe out credit card debt to make is easier to pay the mortgage.
