Advice appreciated for financial situation

[Ally Alvarez]

Long story short- I am wondering if I am in a position to get started with real estate investing or if I should take care of debt first. 

Single income (married with kids) and own primary house with $250k+ in equity. Also fair amount of debt (2 car notes, Heloc used to remodel primary house). 

With those details, I am wondering if we should use the equity in our home to purchase an investment property? Or wait until we have 2 incomes to build more of a solid financial safety net.
