Also the metal duct work in crawlspace has leaks which tapped by one HVAC contractor.

This company charges 15% on top of any maintenance requests in addition to their normal fees but all I need to do is approve the estimates - they do all the work/communication with the contractors.Recently my PM sent me a few maintenance requests: a $1400 to fix some plumbing in a bathroom (clogged and leaking - contractor says they need to cut the pipes, reroute and replace some plumbing, recaulk.

I have lengthy conversations when tenants move in about letting us know immediately if there is a clog, to stop using the plumbing if things are leaking, that they will be responsible.

The reason for the water to be away from the house is water movement from surface water soaking in, such as poor grade or leaking gutters, is it will move the subsoil causing the settling.

These include accidents (I recently had 2 units destroyed by fire), natural disasters (I have had two units each hit by 2 hurricanes), property management turn over (they sell or stop being as good, I have experienced both), or turn over of team (I am turning over at handyman and I suspect plumber), or just wear n tear of property (slab leak in poor location, sewer pipes rotted out (one unit this month), roof, foundation issue, etc.).  

@Sidra Amir I work in a group home that regularly has a pest company come in and inspect for bed bugs with a bed bug detection dog.

For the leak, drywall replacement and so on I offered to pay partially I was not legally bound but I had a booking and needed it fixed fast but I didn't pay much about 20% of the fix for the drywall.

The water department told them that they were seeing continuous usage—AKA a leak.

Water leaks, problems under the trailer ie insulation falling, a tub cracking, a new roof, frozen/cracked pipes (usually in January- and plumbing companies simply will not respond to mobile homes), rotting siding, bad exterior doors etc.
