There are numerous items that can fail a home inspection and not be a deal breaker like outdated appliances, wood flooring that is slightly warped or a few electric outlets that need changed.  They'll annoy the buyer but you just need to adjust your prices to cover the repair costs and the deal will still likely come through.  Other items like foundation, HVAC, infestations or roofing issues could be a deal breaker for a home buyer, but not for a real estate investor.
