Run criminal backgrounds....you may not want to lease to a sex offender or bank robber.

I once picked up a DW with used needles, a penis pump laying around, and a sex swing in the living roomTrailer people have all the fun

We discovered it, did a quick Google search, and learned he was a felon and registered sex offender.Another woman with two young daughters moved in a boyfriend that was a registered sex offender.

Again, there's the general tenant screening and lease creation info you'll find out there, but some online solutions do provide the full spectrum of reporting which can typically include Criminal Reports/Background Check, Residence History/Eviction History, Employment Verification, Sex Offender List, Credit History; along with state-specific residential leases. 

.; any sex offenders, felons etc.

The first one had dealt with 3 management companies in 4 years, the last of which rented one unit to a sex offender who was molesting a 14 year old girl in the apartment.

Bad neighborhoods require 3x the due diligence, on vacancy rates, expected turnover, crime/sex offender rates, gang activity, potential deterioration in surrounding properties, possible exit strategies, on and on.

Whether it's race, sex, age; someone is going to be biased.

If the education turns out to be a good investment perhaps a portion of the cost could come back from the next 6 deals you guys do.We always pay for our learning one way or another.Remember a partnership is like a marriage without sex, but that doesn't mean you can't get screwed!

@Chaunna Henry: I look at the crime maps and the sex offender database to get an idea of crime in the area.
