Low HOA  include water, sewage, cable, internet, and garbage.  

For example, this time I had to install cable clamps in various places where electric wires ran along a wall; for the service cable drop up near the roof; for some conduit that ran electric for the dryer in the basement.

Make sure the equipment being used has a camera at the end of a snake-like cable which can be tracked by someone at ground level.

Used utility vans even with racks are cheap, an old telephone or cable truck, just for properties as your company truck or personal, depreciate with mileage and run the wheels off and just replace it.

What is happening here for some companies is no where near a v shape recovery potential.

Landlords typically dont pay for Electric/Gas/internet/phone/cable TV/oil, so why water?

Comcast cable charges everyone a sports fee so they don't have to charge extra for the sports package and I hate football, baseball, basketball and don't ever watch them.

@Scott LennonAs far as the stock market goes, some stocks have done great because of COVID and others stocks have done bad but in general the stock market has done great with a V or Nike check mark symbol recovery chart.

Cable boxes or cell towers outside you obviously can't fix, but  it could show a possible  non-paranormal source of the situation which might put the tenant  at ease. 

I base that on the fact that you have all of the same expenses as a normal rental so start at 50% and then add in higher management fees, cleaning, extra maintenance, owner paid utilities including cable, phone and wifi, consumables like paper products and higher wear & tear.
