Anyone pay mortgages with credit cards for travel rewards?

[Jack B.]

I've looked into it from time to time, as soon as I find a method it ends up getting cancelled or charging a fee that makes it not worth it.

Even money orders from USPS using my credit card and sending them in to the mortgage servicing company wont work apparently from what I've read because it's considered a cash advance buying a money order. But if I manage to find a way, at 12K a month in payments, I'm looking at basically 200K a year in spend with my personal expenses added on top or about 2-4K in cash rewards each year. 

It's a bit of a hassle, but that's 3-4 trips to Vegas each year....

So has anyone found a way to do this?
