How to decline?

[David Albertson]

I'm new to the rental thing. I had a couple come and see the house and they seemed very nice, educated, drove a BMW and seemed very sincere. They filled out a rental application and I decided to do a background check. All I have to say is WOW! The only thing that E-renter told me was that the DOB for the SSN he gave me was 1936. The dude was in his 20's so I know it was BS. Anyhow, I did some more searching and found that here in kansas criminal records are available online. This guy has something like 8 pages! CC fraud, theft, burglary, collections, DUI, contempt, etc.. The girlfriend also has a recent eviction. Obviously I can't rent to these people but how do I tell them without pissing them off?
