Should I Rent to Prospects?

[Ayodeji Kuponiyi]

I have a prospect tenant whose father is willing to cosign for her daughter and boyfriend. He agreed to pay $600 towards the rent while his daughter and boyfriend take care of of the balance. The rent is $950 plus $25/per pet per month. They have 2 pets which totals to $1K/month. Should I consider them or move on? I agreed to talk to her father tomorrow to discuss & I want to be prepared. 

Side note: the daughter is in school & is a waitress while the boyfriend is in construction and in school.
