You can learn that by either taking a real estate license prelicensure course or, better yet, just go burrow a book on real estate fundamentals at your local library!

Some posts mention fundamentals of a market or growth vs declining markets. 

However, they are not designed on the fundamentals of the business.

Everyone who knew better, who had lived outside Greece and understood that nothing as thoroughly corrupt and also as fundamentally weak and helpless as Greek society survives long, was dismissed with a small smile as naive, as a dreamer, as little boys crying wolf.I was told dozens of times to stay in Greece by the Greeks there.

Reading "Fundamentals of Fluid Dynamics" doesn't make doing the problems simple, interviewing recent graduates about the struggles of boot camp doesn't make a 15 mile hike with 100lb easy, taking advice about how to fly in formation 100ft from another aircraft at night doesn't make it easier (or any less risky).

Fundamentals don't really change.
