No offense intended, but "nonfiction novel" has a rather specific meaning. The prototype (or at least most-often-cited example) is Truman Capote's In Cold Blood, a fictionalized telling, at novel length, of a notorious murder case. The term "creative nonfiction" is sometimes applied to the genre. By definition, a novel is fiction. But Capote, by using techniques of fiction to narrate fact, created an influential sub-genre. If you refer to what you intend to be a nonfiction book AS a "novel" in any communications with a literary agent or a (legitimate commercial) publisher, you will be shooting yourself in the foot. In other words, it is not a small thing.

Clarification of terminology is one of the ways in which folks here seek to help aspiring authors.
