Why do some investors allow unpermitted work?

[Sophia Boro]

There are obvious benefits to acquiring properties that have permitted work, but I want to see if anyone can explain why some folks allow unpermitted work. My curiosity includes how timeframes are affected, the listing price of the home, quality of work etc. 

Anyone have any insight?

Personally I don't care of someone got permits to do something.  If it's done right, I don't need the government having been involved.  Plus, I see all the reasons someone wouldn't want to bother with a permit so I'm not going to lose sleep over their decision.
