Pre-screening a roommate

[Hyung ku Kim]

Hello I am in process of being a real estate investor but due to time and money, I think the best way to start is to rent out my spare rooms. I have one person who is interested and he seems like a great fit. However, the background check (through Rentprep) shows one eviction record and active. The amount is less than $1500, which is more than double of what i am charging the room for. In a situation like this do I ask for an explanation or do I decline the roommate immediately? The amount is fairly low and there might be other side of story that i don't know. I am trying to be open as much as possible.

Thank you
