An important factor in horary (as well as any branch of astrology) is the concept of angularity.

Houses are angular, succedant, or cadent.

An angular planet can act, for better or worse. It’s dignity tells us what it’s capable of whether good or bad.

A cadent planet has much difficulty acting and needs a lot of dignity to accomplish its purpose.

A cadent planet in its own house is still pretty strong but has a difficult time getting things done, although capable.

A planet in detriment or fall, also angular, is capable of acting but not in bringing any good.

A succedant planet is a middling of these two.

With horary stick to the original question and answer it, house placement is more important for deciding the answer to your original question rather than gathering additional info.
