The real estate guru's will tell you that you should call the credit card companies (3 separate companies) who offer the 0% APR and request to get the maximum amounts on all three. Then you can use one CC for anything you need and use the second CC to make the monthly payments along with the interest. The guru's also promote talking to the representative and having them remove all yearly fees. Once the rep helps you with this, then you ask for their supervisor (since they make more money on having calls transferred) and promote how well that rep helped you; then, you ask the supervisor for the same thing.
This was told to me in a seminar (a guru one at that); however, this is dependent on your personal ability to not spend the CC's. I might be the right thing, but I do not know. Also, I am not positive it is 'legal' to use one CC to pay off another. That is what the guru company said to do because the banks cannot tell you that you can use CC to pay off another.
**This is not legal advice, but is what was promoted to fund a guru company class**
