Applicant with questionable girlfriend

[Joyel Curtis]

Hello, very new to this!! Finally received an applicant that fits all my criteria, it's been a long process! He has a girlfriend though who has three kids but has no information for me to verify. He has credit, job and past landlord but she has nothing. I wasn't even going to run a credit report on her because she said she has never had a job, credit card, or past landlord...He says he will cover everything but do I still put her on the lease? What if they break up?
