The electric company plugged in the new meter and drove off, the fire started shortly there after (no interior inspection occurs and the tenant doesn't have to be home).The investigation identified the kitchen stove wiring as the source of the fire (I personally think the stove may have been in use at the time of shut-off and was left on so the sudden restoration of power caused arcing), wiring was not ruled out so an electrical inspection was required by the city and they concluded all wiring in the unit (romex) would have to be replaced due to ambient heat exposure. 

No matter the fan you will have some ambient noise.

If it's ambient air, consider providing a dehumidifier or a/c.  

Aloha,You have already gone FAR above and beyond, given the ambient temps.

But then installing an endless amount of ambient tube lighting.

The biggest risk you actually run is not the failure of appreciation beyond the ambient inflation rate but the fact of depreciation such that you fall below it.   

All-electric house = cost us nothing.By the same token - you and your tenants should be aware:  A/Cs can only cool so far relative to the ambient temperature. 

Derek your neighbors can hear and feel your "thud thud thud rumble rumble" on top of their own music and through their earplugs and over and above an other ambient noise.

I have to agree with the above regarding sealing the crawl space due to high humidity in ambient air.
