My recommendation is that you screen tenants using a service which offers the full spectrum of reporting (job history, rental history, income verification, credit score, any adverse items as a part of their full credit history, nationwide criminal background check, terrorist list check, sex offender list check and eviction history).  

His "past" is just as damaging  to his reputation as someone who's a convicted sex offender.Just something to think about.

This was before premarital sex was invented.

The property owners have no idea if I'm a burglar (I'm not), a sex offender (I'm not), or something similar.

There is also tons of white collar and real estate crime there as well as narco-trafficking, cartel activity, violent crime, sketchy ex-pat American fugitives on the Lam hiding out, sex trafficking, etc. that gets overlooked.

Know what you are willing to "let go" of and I say that because one of my owners ended up selling because she really had a hard time letting go of the fact that guests/strangers were sleeping/having sex in the beds. 

I still don't rent to anyone on the sex offender registry or that has been evicted in the past five years.What, specifically, is encouraging you to change your standards?

I have a certain ratio per100 headcount (not households, not age, not sex) I use when decidingto buy or build in a town.

You don't ever want to accept a renter and then let them move in an unknown person because that's how many renters will sneak in their sex-offender boyfriend or drug-dealing cousin.

They compared LL to sex workers with the LL being thought of as the worse of the two (at least the sex workers work for the money).
