For example, you have to understand that some real estate markets are driven by jobs, with buyers making the decision to move to an area depending on how close it is to where they work.

You also have to realize that a lot of markets are completely unbalanced and uneven. There are many different price ranges in the same area, and they depend in large part on supply and demand.

Neighborhoods make a huge different as well. White collar neighborhoods will typically see houses with higher value. Middle class and upper class neighborhoods will have much, much higher values.
