Are you saying "the corporation" owned the land that the mobile home was on, but that the corporation did NOT own the mobile home?

If the corp didn't own the mobile home, there's no reason to present that irrelevant info.  If the corp DID own the mobile home, your client didn't inherit it.

I'm a bit confused on the fact pattern.

And, off topic, WHY is the real estate in a corp?  BAD, BAD idea.
