However, most of these properties still cash flow well (or enough to cover PITI). 

Here are the screenshots below of me asking the seller about your deposit as well as the email where I explained the same to your Realtor/Mom or whomever she is to you.

This is a lesson learned for me - I know to look for "missing" rooms for this now but I do feel that there was responsibility on your part as well.

The other hurdle is to find a contractor, that is something that you can do as well.

I wish you well in your project. 

Class C is more work than class B, but if managed well can do great.  

They usually sell for a really attractive price because investment property financing is (obviously) difficult, somewhat limiting the buyer pool to owner-operator small business owners (who in turn are typically great clients, as well).  

You have to walk these properties, understand where the hidden costs are outside of the spreadsheets, and understand the geographic appreciation trend and migration and population as well, none of which will be in the questions you are asking.
