As long as you follow fair housing rules, and don't use race, color, national origin, religion, sex, familial status or handicap in your criteria, it is your decision.

They are not allowed to discriminate based upon race, color, creed/religion, sex (though it does not state it, I am assuming this includes sexual orientation), disabilities, familial status, or national origin.

I always do a sex offender search.  

the pay really is more equal for sexes than most other professions. 

They schedule the BPO, I'm there everytime to influence: low comps, repair estimate, reference to the declining local job market, list of sex offenders in close proximity....

Cops can be called, one of them can get looked up, and they can be having passionate "makeup sex" and professing their love for each other within hours.Especially if he is a narcissist, and/or she is a Cluster-B personality type.

ok,it has public records, credit history (of course), employment, collections, criminal report, (most wanted, sex offender, terrorist), credit scores.let me know if you have any specifics and i will ask her for the details.

[if they have sex in their bedroom without their animal in the room, in the bed in fact, with them, are they not disabled enough for you?] 

I have also had the name associated with the number come back completely different, or of a different sex.
