$224k in equity, $800/mth cash flow - how do I grow?

[Nathan Shankles]

I’m 32 years old, and a full time teacher. My wife and I own two investment properties with $224k in equity that are currently cash flowing $800/mth after all expenses and after accounting for vacancy/maint/capex. Our goal is to be at $12k/month cash flow in 8 years. What would you do to grow if you were in my shoes?
