I can’t say that I’m well versed enough with NFCU to know for sure if they’ll double pull. I’ve only been a member with them for a few days. However, based on the reviews I’ve seen and the experience I’ve had with the reps, I’d just give them a call and ask if you can use the same HP. They seem to be very accommodating.
As far as AAoA, and this is totally my opinion not necessarily advice lol. If I had the long history with them that you have, I wouldn’t think twice about it, I’d just go ahead and app. Of course, YMMV and I get trigger happy easily. I hang out in the Approvals section just to get my fix since I’m supposed to be in the garden.
For her they pulled TU. Not sure if it’s the same based on where you live. Most people I see say they pull either EQ or TU.
