The depth does vary somewhat, though the biggest variation deals with the "rough in depth".

For @Chad Lubke , it would help to understand why the variation, so that he can explain to potential buyers of his property, and reference it to any appraiser involved in appraising his property, if there's square footage that isn't actually livable or was measured incorrectly, etc.  

However, there are slight variations.

Try different word variations to see if something else comes up.

There are many programs and variations on the concept but I figured out how to implement it in a spreadsheet model.  

Typical price variation, average or median, will carry an error margin around 10%.

Oh and I'm mostly showing it evenings and weekends because I work full-time, so far that has been ok for everyone.This is what my ad says now (with minor variations), suggestions appreciated!

This really sounds like a question for a lawyer, given variation in state and local laws.  

It's one thing if unpredictable events arise and your put in a bad spot (I almost always waive the late fee in this case), but it's another issue entirely when tenants don't pay on time because they don't see it as being important, they think 'he's a landlord, he's rich, he can wait,' or any other variation of this moronic line of thinking. 

Then a lot of them got cut off after graduation and had no clue what to do or even where to start, no doubt in my mind that my parents variation of financial support made me the way I am, and I'm very thankful for it.
