I have an annual bug spray for the property.

I do make weekly trips to water new trees over the summer.I provide filters for tenants and personally spray once or twice a year and write off the chemicals.  

This beautiful wall they painted black and they put this stupid plastic white exhaust hood outlet in the center of it...I ripped it off as soon as the trucks arrived on site so it wouldn't show up in any photos and put it up later after I spray painted it black.

And unless you're in a structured class or training session, HOW will you keep all this info from spraying all over the place and you're getting buried and overwhelmed with info.Action:  Make a new tab on your excel spreadsheet called. 

You are likely going to be sprayed with so much information from a fire hose, and you need time to be able to sit down and review your notes and pick through them and really understand certain parts of what you learned, and how you are going to implement it within your business!

Slideout broke and got stuck open.Water heater element fried from not filling with water prior to turning on the heatWater heater cracked from not draining properly in the winterPump fried from leaving it on prior to closing up the camper then draining the lines at the dump station.Blackwater valve broke, spraying sewage all over somebodyCharging converter went outCable for pop up broke2 people had roof leaksI could probably go on, but you get the point, there is more maintenance with a camper than a house or apartment, and if someone isn't familiar with that particular trailer it's easy to screw things up.

Dense  packing exterior walls in older homes or   adding spray foam to a rim joist and 6 mil poly in a crawl space.

Window screens/wood I'll just spray black.

If the tenant is burning incense or scented candles or has sprayed air freshener just before inspection, it is a red flag.Even with all of this, a smoker sometimes gets through the net.

The only actual service you get for your yearly payment is a cursory spray around the house- once.
