The Chase Slate card has 0% intro APR for 15 months on purchases and balance transfers.
The car loan payment is considered a purchase.
No I won't have every penny paid off on the CC by the time the 15 pay cycles expires.
When the intro rate ends, I plan to transfer the remaining balance to a new 0% APR CC and finish paying it off.
Now if they stop releasing new 0% CC's in the next year and a half, I might get bit, but it's not likely. Risk is low.
Be very careful of this. if you miss the deadlines by one day, or anything goes wrong, then there are lots of loans that kick back in retroactive interest. depends on the exact terms they offer you, each company is different. Even if you plan on paying off the credit card near the 15 months with another credit card, you don't know if you for sure can do that without a transfer fee at this time.
they offer these great deals hoping you will mess up and they will reap the rewards in massive interest. also think, how secure is your job, because what if near the 15 months you got laid off or had other issues crop up, could you deal with both problems at once?
If you do this, yes it will save you interest, but i would only do it for the smaller of the two balances. once that smaller balance is paid off, put all the payments you were using on that to snow ball your student loan away quicker.
