Did René ask this question correctly?
Instructor: Así se pregunta Had the owner rented the theater before to other people?.
René: ¿Había el dueño alquilado el teatro antes a otras personas?
Is the question by René correct with " el dueño " coming between había and alquilado?

The subject could go before the verb without affecting the meaning of the question:
¿El dueño había alquilado el teatro antes a otras personas?
In fact, this construction sounds more natural to me. Your version sounds a bit anglicized.
If el dueño is already know from prior context, all you need to say is ¿Había alquilado el teatro antes a otras personas?
If he is unknown, the phrase could be said the first two ways mentioned and in addition: ¿Había alquilado el dueño antes el teatro a otras personas?
Sentence structures are many times regional.
