Applicant with Massive Student Loan

[Sean Pour]

My applicants are partners, currently living in a one bedroom apartment with about $2,000 monthly rent. They are applying for my 2BD condo with monthly rent of $2,200. One applicant (She) is making a good salary (x3.8 rent) and have a relatively low debt ($570 obligation per month). The other applicant (He) has unstable low income (x1.3 rent) with about $300,000 student loan ($2600 obligation per month). My challenge is when looking at their total net income, they are making about $6,800 net, but after deducting $2,200 rent, $3,200 total debt obligations and $100 utilities, they are left with only $1,300 per month to live with. I would consider $1,300 per month a very low amount given the high living expenses in California. They seem to be doing fine as they have managed to keep a balance of about $6k in their bank accounts but would I consider them very risky and I don't think they can afford paying $2,200 rent without facing financial hardship. Any thoughts would be helpful. Thanks.
