Choose the right word to finish the real estate agent's highly dramatic property listing.

We are selling a spectacular Victorian mansion _____ roof has recently been replaced and supposedly hosts a family of friendly ghosts.

The correct answer is whose.

We use whose as a possessive relative pronoun. A common misconception is that "whose" can only be used for people, but it is actually perfectly correct to use it for inanimate objects and animals as well (meaning the roof of the mansion).

Watch out for the trap: who's means "who is" or "who has" and cannot be used for possession!
