We have checked every sex registry we can find. 

@Armand SotoI seek out felons and sex offenders they make the best tenants they only have one goal and that's to pay their rent and repair their life

Heck, I even had tenants complain that other tenants were having sex too loudly. 

With stocks.... a story from the main stream media about a CEO’s sex scandals can reduce the value of your stock for that company.

Just by asking this question in a public forum you're butting up awfully close to discrimination pursuant to The Fair Housing Act.FHA prohibits discrimination in housing based on race, color, national origin, religion, sex, familiail status, and disability.There are some exemptions, but you'll want to be certain you're on the right side of those if you're going to use them.Now, with that said, you aren't required to bend over backwards and make obscene concessions just to make the property usable.

Like a sex offender or violent criminal?

The law make it unlawful to discriminate on the bases of race, color, religion, sex, and national origin, disability, and familial status."

I do not go on any appointments where I will be alone with the opposite sex without my wife or one of my older children with me.  

I don’t want anybody to visit me for one day, have sex, abuse the cabin and leave the next day.

Especially with sex offenders, and habitual offenders in certain types of crimes.There is a reason why the entire community usually gets notice in the mail when a sex offender is moving into where you live.
