I find it hard to imagine that tenants in Puerto Rico routinely have so much cash on hand.

., it is a matter of routine inspections to discover if they are complying.

Enter the house for a routine inspection (with proper notice) and say look for ANYTHING.

There’s no research at present proving that routine duct cleaning improves the air quality or reduces dust in your home.

That sounds like too much for me to spend right now.In addition, there is a clause in the tenant lease which states "Tenant shall conduct routine landscaping of the Premises, including regular mowing of the grass, removal of leaves and small fallen branches, regular removal of all weeds and grasses in landscaped areas and trimming of plantings, including shrubs, unless otherwise provided by the Owner or a third party such as a homeowners association."

BTW, I routinely have county officials tell me that their placed applicants "easily" meet the payment qualifications for our efficiency apartments. $525 rent, $733 SSI payment.

Same, I can get over the money (though I would love to have it) but I can’t get over the idea of him thinking this is something he can just routinely do to landlords

Costs of cleaningA landlord may properly deduct from the departing tenant's security deposit to make the rental unit as clean as it was when the tenant moved in.241A landlord cannot routinely charge each tenant for cleaning carpets, drapes, walls, or windows in order to prepare the rental unit for the next tenancy.

Even then, the “big boys” playing with leverage in the markets you mentioned routinely run into issues using leverage.

I have one location that routinely attracts young professionals and they consistently are great tenants.
