Deep cleaning and fresh air circulation will help with the residual odors, but it just takes time. 

I didn't pull these numbers out of thin air, they are the numbers in the specific area I am interested in. 

.: 50% deposit at the time of booking.If they cancel >30 days before check-in, I refund everything.15 - 30 days before check-in, they forfeit the deposit.Full amount due 14 days before check-in.Cancellations <15 days before check-in results in forfeiture of all funds unless we're able to book someone else for the same time/rate.Both VRBO and AIR have my guests pay in full when booking which I like.

I like podcasts for entertainment but they're often too out-of-date by the time they air to be particularly timely since many of them record one month or more before coming out. 

Hardly anyone had air conditioning - window or central.

For example, having multiple air conditioners or space heaters running for long periods on the same 15 amp circuit.

From hot water heaters, to air conditioners, to roofs, etc - so note the condition of all the major systems in each unit.  

I am a huge fan of Air DNA as we already run an air bnb in San Diego.

I currently have a 625 sq ft cabin on six acres in a great air bnb location. 

If your lease has these terms, then turning off power would be a lease violation, and would potentially justify retaining the security deposit.Yes, pipes could freeze in the winter, but there are also other problems that could occur with no power.Most areas of NC are highly humid, and not having AC and consistent air circulation in the summer could cause issues with humidity buildup inside the house, which could produce mold, rust, peeling paint, and/or wood rot.
