Pay off Student Loans or Keep Real Estate?

I have $80,000 in school debt. I'm paying ~$1,000/month for 10 years. I have a condo (paid off; $120,000) that is bringing in $850/month. I also have a mortgage on condo I'm currently living in. I pay $650/month for 30 years. I just started a business and I hope to break even by the end of the year. 

Should I sell the condo that I have renters in and pay off my school debt or keep it?

Thanks, Rookie.
