They hop from one dwelling to another in a parasitic pursuit of a host, enticing you with the promise of the simplest long-term behaviour of paying their rent at the beginning of each month and keeping your house clean, just enough to ensnare their unfortunate host, no matter how good his intentions or faithful his actions.They show their welfare stubs during their application to indicate that all they have to do is sit and breathe, and out of your own tax dollars will flow in the rent to which they agreed in writing.

Well, perhaps they might decide that the best use of our tax dollars was to fight malaria in Africa and the worst use was the war on terror?

I have made the point I intended to make - parasites absolutely do screen their potential hosts and with certain steps can be avoided, whether you realize that or not.  

No you don'ti won't make friends on BP saying that but real estate in itself is already a parasitic activity heavily weighting on households, but realtors and wholesellers are the epitome of a parasitic cartel providing almost zero value to society and the economy from a general standpoint.

Venture capitalists may be projected as parasites on their image, but it certainly is one of the best ways to extract money.

There are many nasty diseases you can catch from the large populations of insects such as malaria, dengue fever, zika, typhoid, yellow fever, bacterial infections, etc.

To kill the parasite you risk killing the host.

I'm not a human doctor but I am a veterinarian, so I have a pretty good knowledge of the medical field and parasite issues :)The tenant should be examined by their own doctor......

Doors (or clients) that require extensive and constant attention from my staff are not long for this world and will be cut loose.As @Richard F. mentioned, clients fall into those two categories (micromanaging, time-sucking parasites who place zero value on the value of your time, or the "don't bother me unless the house burned down" clients).   

Instead of sinking so much money into Dead Equity, maybe instead: fully fund their kid's college fund pay off other non tax deductible higher payment debt that's eating them alive like a fresh eating parasite!
