I never thought of that even though I have put in for that in the past (I’m in the Air Force) without success yet.

Please be aware that with this type of occupant, you must consider the 'retribution damage' they might inflict on the property before eviction takes place. 

There are bathroom fans that you can buy which also act as a whole-house fan (run on a low and quiet setting even when not turned on) and it's really good for any unit to recirculate the air. 

Just pulled the 7% out of thin air :)  Plus if you can avoid a Realtor that saves you 6 or 7%. 

And this ride is only partly dependent on the real economy as long as we can create more money out of thin air.

They are set to replace the main line to the house next week and I will be taking before and after photos to make sure nothing is damaged. 

I found his company works well, efficient and respond reasonably quick.I had one issue previously where tenant moved out and I have to pay for the entire damage. 

As a fire-damage Restoration contractor myself, I’m very sorry to hear about this, however I agree with @Chris Seveney’s assessment—probably not a fight you are going to win.

Just go replace the air filter once a quarter to check in on it and if any maintenance comes up, you can call the plumber, electrician, handyman, etc.

It has forced air heating but no cooling unit, is having a cooling unit a necessity?
