Is Navy Federal Credit Union a good lender?

I've read some reviews, and it seems it's best to go through a broker when choosing a lender, but we're not in a position to pay another fee. We need to get a house fairly soon because my brother-in-law loves with us and has a lot of needs. I'd be able to get a loan through NFCU, and their rates look pretty good. Has anyone used them and have any insight? We'll have to do most things online or through the phone because we can't both be away from my brother-in-law. He has to have someone with him 24/7, so it'll already be maybe a bit more stressful.
