Memphis, TN is on the other hand is very unfriendly to landlords, lots of crime (I've been personally robbed there haha), and lots of gangs and drug use.

Build routines (no different than dieting, working out, etc.)5.

Facebook Marketplace is full of drug addicts.I used to find professionals on Craigslist 

They recruit, interview, check references, skills test, criminal background check and drug test. 

I had an extremely similar situation last year, it was a property I was fixing up to sell, the main contractor had some issues (maybe drinking, drug or gambling) and kept asking me for money saying he needed to pay the crew and has been working really hard.

You can see felonies, evictions, drug offenses, etc. by doing that.  

(Gambling, drugs, divorce and lust)

Keep in mind GDP is not income and taxes, thus we are far above our economic spending level.Drunks, drug addicts and gamblers have to hit bottom before they will self correct.  

The stigma of bad/crazy/poor/drug-using tenants has always deterred me from considering renting to those who have vouchers.

I suppose if someone's felony was some kind of drug use thing 30 years ago and was a one time thing I might consider it.
