I would get a complete credit report. And, how long have they been at their current job and what sort of income? My past tenants had gone through bankrupcy because of medical bills. They moved here and left one place because it sold, the next because our rental came up and it was nicer and closer to their work. They always paid on time. In fact, the next renter who also went through bankrupcy have paid on time. That being said, I would still be careful in checking employement and income. I wouldn't completely count them out because of the credit "number".
