I'm relieved to see that my paranoia has a purpose.
I should probably push the money to them instead of letting them pull it. The "good" news is that it's just the P&I payment, no impound account or add'l principal payments, and we're not going to pay them a penny more than we owe them until we pay it off after my 80th birthday...
Your post reminded me that we got a letter last week from Fannie Mae announcing their ownership of our mortgage but cautioning us that PenFed was still the servicer. I've never received one of those letters before.
