I am finding myself in their unit doing routine repairs like fixing the dryer duct, repairing the toilet flush valve, etc. at least 2-3 times per week.

When I work with an agent and they aren't panning out, I never want to lock myself in to that person. 

(see below)Above tenants have destroyed our bathrooms due to constant nasty toilet water damages.. and constant noise violations have caused my family to suffer from sleep deprivation.

I need a toilet flange removed. 

But, you never know what might happen in 6 months if the eviction moratorium is lifted and people are still out of work and the economy is in the toilet.

The last part you said is the problem with this tenant, they think we are on-call.We put a clause asking them to address any repairs under $200 just for this reason so they don't keep bothering us for leaky faucets or a toilet that is clogged.

You can't work on the property as it must be a passive investment (e.g. you must hire someone to fix the toilet and can't pay the expense with non-retirement funds).7.

Let them deal with your property manager exclusively, otherwise you will receive calls in the middle of the night about repairs, clogged toilets, etc.Never give your tenant your home address or home phone number for your safety.

These seem like necessary items, but most clogs are charged to a tenant because it is their hair or their excessive use of toilet paper that causes a clog. 

We have one guy that manages the properties, from fielding calls about clogged toilets, to ensuring tenants are taking care of the property, to scheduling the lawn to be mowed, he is the go to guy.
