Well, I wouldn't guess they would close or CLD for it, but stranger things have happened I suppose.
However, if you really pay on it for PIF prior to BT rate expiring, one would think that wouldn't be the case. But one could be wrong.
Let us know what you decide.
I'm actually going to use PenFed's BT 2.99 for life of transfer to fund a home improvement project. Cheap money...got deposit accounts paying more than that.
It is a nice offer. I really want to take it but I'm worried they will cancel me or CLD me.
