Carson Dunlop material isn’t bad. It’s not at the level InterNACHI’s courses are at, but there isn’t anything wrong with it. Carson Dunlop is much better than AHIT IMHO and CD’s material is much more in-depth than AHIT’s. Don’t get me wrong, AHIT is a good school for people who have zero construction experience; very basic/entry level.
Regarding the currency of the Carson Dunlop courses, I can tell you that the courses are substantially updated from what they were a few years ago, and are reviewed and updated on an annual basis.
Nick, I appreciate that you indicated that your opinion was based on a few years ago, but I can assure you that being up to date is very important to Carson Dunlop, and that there are processes in place to make sure that this is so.
I used to work at Carson Dunlop, so I have first-hand knowledge of this. And I don’t work there anymore, so I don’t have any reason to lead anybody on.
