JMT21, it takes about 45k from Private to Multi Instrument CFI at UND, plus school. It takes about 20K for all the ratings at my FBO excluding the additional hours I have to fly to reach the commercial license requirement of 250 hours. I was accepted into the program for this year but decided not to go when I found that past flight experience and hours do not count toward the UND flight training.
Now that I think back, I am so glad that I didn't go to UND. Can't beat the SOCAL weather, the nice mountains and elevation changes, flying is never boring here.
