After Scarfo's mother died who got the property in Ducktown? Nicky Sr? His sister (Phil's mom)? Nicky Jr? Any idea who owns it now?

I know originally Scarfo's father owned the property then i would guess it went to the mother after her husband died back in the 1970's, but then who got it after Scarfo's mother passed away? Wasn't Scarfo's sister in the WPP with her son Phil under a new name? Just curious about the chain of ownership and who owns it now.
