First time screening tenants

[Joe Nguyen]

Hello folks,

I'm renting out one of my properties for the first time. After a few applications I've finally narrowed down to one applicant (with his gf). Besides the information Zillow provides (emerging credit score in the mid 640s), I'd like to issue a background check and credit inquiry - question is, can someone please recommend some of the good platform to run a credit and background check? Also, I understand that there isn't one single platform that can be reliable 100% and provides 100% of someone's information... so of course I'll take the best judgement possible of the information being provided. I've heard of Smartmove and TLO... anything else? 

Also, one of my tenants does not work (the gf) and she receives ss disability, albeit the male tenant has decent income (4x rent) - should this be a concern for any future issue should I decide to sell the property and ask the tenants not to renew their lease? 

This is in the state of Texas, btw.

Thank you everyone for your inputs.

I used Transunion SmartMove 10+ years ago and was pretty happy with the results. They are still one of the top results in a Google search, so it must be liked.
