The inspection clause seems like a clear walk away situation, so from the buyer's side it seems like no harm, no foul.

Saw this while trying to research how to get rid of cigarette smoke https://www.epa.gov/indoor-air-quality-iaq/ozone-generators-are-sold-air-cleaners#ozone-health anyone have thoughts on how harmful ozone generators really are?

It seems to me this is a common occurance...  

My understanding of ground is that if a fault occurs in a metal object like say those old clunky drills the electricity will use the third copper wire, which must be grounded to something like the water entrance pipe, instead of shocking the person holding the metal tool.I just do not see how grounding or lack of grounding would cause a TV to burn out.

The longer the drainage problem continues unresolved, the more likely property damage will occur.  

That is probably what the squatter is attempting to do.I've actually tracked deals in Chino Hills, which not common, however vacant abandoned properties occur everywhere; even in upscale canyon area where I live.

I know about the potential terror tenants who destroy the property, but that can occur anywhere right?

We take full responsibility for the schedule and do the best we can, but delays do occur. 

As you are doing, get roofers out to give you an estimates so you know what is occurring and what is NOT occurring. 

Since you have already talked to your landlord and since this is not a one time occurance, if I were you, I would contact a tenant advocate in your area to help you resolve this.
