Some quick and obvious ones include: 1) not being able to find a good contractor2) even if I do, not being able to get him/her/them to walk the property during the diligence period to give me a thorough scope of work3) if I need to back out of the deal after seeing the inspection & SoW, that particular contractor not wanting to work with me again and then me having to start the contractor-finding process all over again4) not being in a good position to manage the contractor throughout the process, thereby leading to an over-time and over-budget (and potentially incomplete/subpar) rehab.I could go on but you get the picture.

When we purchased the property, the selling bank was very difficult to deal with and absolutely refused to allow us to have any utilities turned on during inspection, and now I can see why. 

Then I can order an inspection and title search.

Found on the MLS, and as an old home, it did very poorly on the inspection.

When you get an inspection report if you're not aware of those sorts of things or if you don't have someone guiding you that's aware of that sort of stuff you'll probably just get scared off.

ALL BECAUSE OF OF INSPECTIONS .    

I have the owner’s permission to enter the house for inspection, so I know the situation before bidding at auction.Over the past couple of months, I stopped by a few times to look in the windows.

I did let the seller know I would need a home inspection. 

Get a Licensed roofer to inspect it and give you a letter certifying it's condition, show this to the Ins.

@Connor Cushman I'm working on a property using a 3% conventional loan right now and have explored 203k loans for the properties that won't pass inspection.
