From what I see all the people answering to me here (and there are so many) are just coming against and refusing to agree with my simple statement: "a landlord is not above the law or norms by its personal choice or presumed capability to judge what he don't know" or as well "a landlord cannot deny or miscarriage a service to a stranger without a known valid reason and at the same time pretend to be operating professionally or loyally to the moral"Basically I'm telling if you are not able to do your business correctly it would be better to find someone else than you, mainly when your ideas about "squatter" or fair treatment are coming from ignorance or completely invented. 

This self claimed "Drug Addict to CEO" doesn't pass the sniff test in my opinion.

Can I purchase the rods and charge back to tenant as missing/damaged window treatments when originals were blinds?

I'd venture to guess your tenant is a criminal or drug addict of some sort.There's some truth in your thought but he's actually a really nice hard working young man. 

No problems with rust but do have to deal with hard water; they have a chemical treatment called a pillow that takes care of that.

Negligent forest management, drug addicts, or illegals? 

@Tom Rairdon If you’ve owned your short-term rental (STR) for over a year, it likely qualifies for long-term capital gains (LTCG) treatment, taxed at lower rates (0%-20%) compared to your 33% ordinary income bracket.

I cannot, in good conscience, support a mentorship program that fails to prioritize the well-being and fair treatment of its employees.

We run a background check to look for drug distribution charges and sex offenders3.

Every adult should be fully screened to ensure you aren't renting to a violent criminal, drug dealer, etc.
