Just be aware that you can't actually "prepay" your mortgage in terms of say paying the next three months worth of payments and then being able to not pay them should something arise. It doesn't work that way.
When you make a mortgage payment, the payment is applied first to any interest owing, and then to principal. In the early years of a mortgage, the vast majority of the payment goes to interest.
If your mortgage payment was say $1000 and due November 1, and you pay $3000 to "get ahead," the accrued interest would be paid first, and the remainder would go to pay down the principal balance.
But beware, your next monthly payment is still due December 1 for the full amount. You have not prepaid your payment, though you have prepaid some of the principal.
Hope this makes sense. People often get in trouble thinking they have paid their loan ahead by three months, then they want at some point to take a three month break from paying, and then they are in default.
