We've all gotten pretty creative with moving money around - here's a simple mortgage move:

1) Homeowner's Insurance - Many carriers will take CC payments. Sometimes you need to make first installment by check, but then can pay w/ CC.

2) Property Taxes - I don't know how widespread this is, but at least in NYC you can pay property tax online w/CC and no extra fees! It's worth checking.

You can usually notify the mortgage company in advance so your escrow withholding will be reduced.
