Potential Meth House Rehab

[Justin Johnson]

Hello!  So, I have an opportunity to buy my first off the market property and I wanted to first get some advice from some people who may have been down this path.  The property is a quad, which is exactly what I have been looking for, but the neighbors have lovely dubbed it "meth mansion".  My questions are

Is it worth trying to rehab a known drug/meth house?

What kind of work and rehab needs to be done?  Is it a *total* rehab of everything (completely gutting the place and redoing it from the inside out)?

What questions should I ask the current owner who is extremely motivated to sell the place?

What kinds of environmental studies/inspections should be performed?

I am just trying to get good grasp on things to see if it even is worth looking at.  I could make a huge impact on the neighborhood, but at the same time, it could be a horrible nightmare of a project/property.

Any help and advice would be greatly appreciated!

Thanks,
JJ
