Credit Card for Forclosure Court? NY

[Sean Brady]

Hey all, I've heard different things about this being legal or not so I wanted to know if anyone knows anything. 

I figured if I can do a cash advance on my Credit Card, and roll that into a 0% APR promo card why not just use those proceeds to fund the purchase in court for the 10% down payment. Then I got 30 days to close/ find my end buyer or I lose it all. So whats to stop me with taking that cash to the bank and Bid away at auction?

I've heard using credit cards for down payment assistance is illegal. Is that illegal for court bids?
