If paid, we leave it at that, if not we will file a case with the city for damagesLESSONS LEARNED:Give someone an inch and they will take a footCredit score and income don't guarantee the quality of the tenant To everyone out there wanting to be a landlord - This is all part of the business and this happens, with more units you will have these things come up, it is almost inevitable People can be great, but might become addicted to drugs while living in your place.

Bottom line is cheap, easy money for so long has created a massive addiction.

It became addicting.

Found out from the property manager the tenants were drug addicts.

This is a bit addicting. :-).

When you're ready to buy your next investment property (it's addictive!)

That is not my business model, but I am not going to judge other people for providing housing to people that have drug addiction problems. 

Buying in a carefully selected growth market where prices have historically outpaced inflation and where economic indicators are strong on the theory that you can achieve a substantial total return over time is not "speculation"; buying a run-down property in a "cheap" market where healthcare is the only growth industry because of an aging, industry-era crippled and/or opioid addicted population on the theory that monthly rents will unexplainably outpace the deteriorating housing stock certainly is.                  

Addicts don't work that way. 

I bought a few buy-and-holds and could tell the addiction was imminent.
