Skip the inspection, bring in a contractor?

[Sam Mitchell]

I've made an offer on a duplex that is in terrible shape. It most likely will need to be completely redone, though the structure itself is only 18 years old. During due diligence, I'm wondering if there's any use in paying for having an inspection done. The property is sold as-is, and I know it's messed up. Would it not be more cost and time efficient to use this period to bring a couple contractors through to get estimates on a rehab?
