Maxing a credit card for down payment on property

[Chance Cooper]

I found a house the other day for 49k, a house up the street is selling for 86k and another for 76k. I called on a few houses in that neighborhood and rent is around 700-750. 

I would need $9800 as my 20% down, have you ever thought about or actually maxed a credit card to use as the down payment?

Is this a dumb idea?
