Why would you have stock in someone else's mortgage?? Stocks are something that trades in the financial markets. Mortgages are on a house or a business or piece of land. Unless you are on the title (of a house or business, etc), you have no ownership.

Why exactly do you think you would have stock in a mortgage?? Are you a spouse or something?? Any reason you aren't asking them??

how do you have stock in a home and NOT have your name on the Mortgage?

Yes

What's the issue here?

I believe you can take over the home and you need to talk to the one who owns the mortgue? mortgage?

Yep that's basically it.
