I am trying to educate myself on the process and effect a property with this "stigma" would have on resale.If you were to find a property with structural repairs that the seller discloses, how comfortable would you be in proceeding?  

Look into house-hacking, sub-leasing when it's legal, options like these are lower cost effective ways to get started that you can actually leverage to successfully invest long-term.Otherwise, there's no golden goose, and no get-rich quick option in real estate, same as everywhere else.I hope this helps, reach out anytime with questionsBest,Ryan

Is it more cost effective to repair cracks and apply stucco/paint or to place sheet rock over it?

Yes, they are better, but rehab the ones in the other less desirable areas nicely (and cost effectively) and you'll easily rent a 2 or 3 bed for $800-$1100 in the other C neighborhoods.
