In doing my homework, I found that two of the tenants are on the sexual offender list (they have lived in the complex for 9/10 years).

Imagine someone having gotten a key (for whatever reason, however, doesn't matter), and using it to go in and commit a sexual assault, murder, etc because a landlord didn't change them between tenants.

It contains a notice to the purchaser instructing that all due diligence with respect to adjacent parcels be performed and includes instructions for obtaining information on sexual offenders from the local police department.Have any of you run across similar statements in property disclosures before?

Family Member is defined as follows, regardless of actual or perceived sexual orientation, gender identity, or legal marital status:  child, parent, or grandparent; o a child is defined as a son, stepson, daughter, or stepdaughter; o a parent or grandparent includes a step-parent/grandparent or foster parent/grandparent;  spouse or domestic partner;  legally adopted son or daughter, including a child who is placed with the Borrower by an authorized agency for legal adoption;  foster child;  brother, stepbrother;  sister, stepsister;  uncle;  aunt; or son-in-law, daughter-in-law, father-in-law, mother-in-law, brother-inlaw, or sister-in-law of the Borrower.Or these other exceptions:(3) Exceptions to the Maximum LTV The 85 percent maximum LTV restriction does not apply for Identity-of-Interest transactions under the following circumstances. 

Do they only check for violent/sexual crime and threats to other tenant, or is a marijuana felony usually enough to keep a tenant from renting a place to live?

There was one sexual offender that was registered with the county that lives there.  

Any crazy neighbors or maybe look at the sexual offenders map and see if anything is close to disclose.Killing a deal isn't too difficult if you are getting fair market value.    

But now my wife found stories in the news that the guy is facing felony charges surrounding his use of computers to solicit sexual contact with a minor.

Also, are there any sites that some of you use to screen tenants (i.e. credit, background, sexual abuse, etc. hopefully country wide)
