Here's my thought process in (a condensed version of) pros and cons.Pros:-I have an agent I trust, with whom I served with at the end of my enlistment.

They said they could cover the condenser, which was bad. 

That might help me figure out how to better explain the plan, or help me condense the explanation. 

Great statement Don - there’s a wealth of wisdom condensed into a single sentence!

For example, if the AC condenser and plumbing somehow fail at the same time 5 months in (extreme example, I know), that $130 a month won't mean anything as you'd need 5k-10k to remedy this problem.

If I don’t get any replies, I’ll try condensing it.If I need to, I’ll pay for help on this matter.

Took him ONE minute to flip the breaker in the basement for the AC unit (the blower was still running on a separate breaker, but the condenser was not).So, the first time I had a tenant tell me that their dryer stopped working and that they need a new one, my immediate response was “did you check the breaker?”

water heaters:  flush them every two years, replace anode every 4 years.dishwasher : clear food trapa\c pour clorine through condensate drain etc

When you say no AC do you mean it doesn't have a condenser presently or the home was not built with central heat & air. 

Invest on a moisture sensor for the A/C system which automatically turns off the A/C when water accumulates on the bottom of the condenser.
