re: Possible to pay off someone's mortgage anonymously?

Mortgages fall under Fair Credit laws. To even speak to a bank about someone elses mortgage you must obtain 3rd party authorization from the mortgagor

So I say legally no.

Now if a local bank lends it's own money and you know someone at the bank....perhaps but I still think it would technically be illegal. JMO

Now if you could obtain their account number of the mortgage than I don't see why you couldnt do it. Or at least pay on it. However I don't think you can find out the payoff without the authorization from the mortgagor.

Sorry i did have my terms mixed up. So duly noted and corrected.
