If you're looking for fun, it might be here

This conditional construction strikes me as problematic, since the consequence (fun being present) doesn't follow if the condition (that the reader is looking for fun). If the author believes fun exists at a location, hypothetically the fun is persistent whether the reader is looking for it or not.

A conversational tone suggests that the writer means to qualify the reader to have the next part revealed. As in:

"If you're looking for fun..." meaning "Are you looking for fun? "
in that case, I'll tell you that it might be here.

Is this construction proper?
