The banks are really surprisingly good about forwarding payments, I found that a mortgage had been sold months before but the autopay from my bank kept working; it wasn't until I went to login that I realized it had been sold off.

Exactly. I've had a bunch of different mortgages over the years. Plenty of them have been passed around, but I've never had to sweat the details. I just set up autopay and forget.

So it isn't so much about the mortgage being sold, but whether servicing is transferred. If servicing is kept them the servicing bank forwards your payments onwards.
