I've had two "incidents" through AirBnB guests, which I honestly don't think would have happened through VRBO, so I would like to see AirBnB up their security and background checking.

The seller has been arrested for alcohol/domestic related incidents.

He did not, and blamed the incident on them and did not repay the debt.

Although eviction is a necessary evil focusing on exceeding the customers' expectations can be more profitably and reduce the incidence of eviction.

Most incidents in the southeast of town. 

So after that Incident didn't want to go through it again without knowing if its going to work or not.

(doing it from memory but it was something like 2x's for conventional resistance heating vs electric)As long as the furnace is properly vented (ie no birds or rodents have climbed into the stack, I would stick with natural gas.)Contrary to the isolated incidents that hit the news, natural gas is very safe, and carbon monoxide poisoning from a natural gas furnace is almost non existent. 

Make sure you have a solid lease agreement with every incident you can think of and let them review your lease to make sure that they are aware on the front end about their responsibilities as a tenant.

But taking everything at face value...(1) The letter states that the incident took place 6 weeks ago.
