Navy Federal Credit Union Home Loan Questions

[Cody Tittle]

I have a few questions, some may be simpler than others. For starters, I am in the Army Reserves, just commissioned last year though, so I'm not eligible for a VA loan.

First, does joining the NFCU effect my credit score?

Does anyone know if I'd be eligible for the zero down mortgage on a primary residence?

Also, what does the rate increase look like for their ARM? I've heard that some are 1% per year after the first 3-5 years of fixed rate?

Yes I know I shouldn't go into a deal with no money, I basically have enough for reserves or a down payment, but not both. That's why I'm looking for a zero down loan. Thanks!
