Tenant Screening single mother of 3

[Jerry L.]

No offense to you single mothers. I'm in the process of screening and one interested person is a single mom of 3, she's rented her current place for 5 years, has excellent credit, and no criminal history. At least she says that, I haven't ran a background check but I will when I'm done choosing the tenant pool. Her only source of income is from her ex-husband from a maintenance package (child support), and by working part time as a substitute teacher. 

This is my first time looking for tenants, for your experienced Landlords, would you consider her as a tenant if her background checks out or is that already a red flag knowing she doesn't work and mostly relies on child support?
