Our state we worked this Oregon and Washington have made it illegal to do most anything with a home in pre foreclosure there are very stiff rules and some of it is criminal so we no longer do it at all.

It's about $20 for a basic criminal search and seems relatively thorough. 

You may have civil or even criminal liability issues with non-functioning windows in the event of a house fire. 

However, in that case consider the elements of criminal trespass. 

My background check includes a criminal records check. 

They are fully documented and fully legal.I don't know if a credit/criminal would show anything but you should definitely require proof of their ITIN to verify identity and their legal status.

Less is more some times. examples: Favorable Fico credit score > than 620 (Suggested) No significant criminal history.

We're able to compensate for that by requiring a co-signer (no double deposits allowed in NH), but the inability to validate identity on the screening platform through questions based on credit bureau records prevented him from being able to complete the eviction and criminal history screening.

You still run credit/criminal, check references, verify income, etc.

I get reports back on their credit, criminal background, income, and eviction record and then it gives you a recommendation to rent or not.
