I sold property this year (not primary res.) For 90k. I am holding mortgage. 20k down, payments for 10 years. Does this count as investment income to make me lose EIC?

I recieved after fees 13k this year, buyer has been paying for 6 months. Have 40k into property. My gross income from all other sources is approx 48k. Married with 4 children. Trying to figure if anyway to still claim EIC this year. Thank you.
