Credit Card in Real Estate - good or bad?

[Jon Elson]

What would happen to my credit score in the end if I were to use an interest free credit card to finance a flip, flipped the house, and paid back the card?

I understand that my score would initially go down b/c I am using more than 75% of my available credit, but once it was all paid back off, would my score go back up to it's original level, higher, or lower?

Any ideas @Albert Bui ?
