A boy pushing a girl on a toy SUV.
A boy is pushing a girl on a toy SUV inside of a nice house.
There is no evidence from sentence 1 that the boy was pushing the girl on a toy SUV inside of a nice house.  He might have been pushing her in the park or in the backyard outside.  I he was pushing her inside it could have been in a run down house.
Doesn't mean that the nice house is theirs.
The boy and girl are inside of a nice house
