Investing in homes with chinese dry wall? Any experience with this?

[Jaime Penix]

I use to see homes listed with CDW but the walls were still up. Now I see a lot of the homes with CDW have been gutted, usually sparing the wiring and tubs. The prices are discounted but not as much as I think they should be. My cousin own a home tainted with CDW and he got an estimate for 90k for a 2200 sq/ft home. Surely this cannot be the best deal out there.  Silly me, I have been tempted to dabble with this, however all of the contractors I ask about it say the say thing. "I can't tell you until I see the house". Some even admit to not doing a CDW home before. And of course when you are available to see the home they are not. Nonetheless, the question is has anyone had any experience rehabbing these homes? The pitfalls of such an endeavor? What was the cost of the finished job? Is there some type of chinese dry wall remediation certification needed at the end of completion?
