Become Consumer Debt Free Before Investing?

[Bri Deel]

I've been contemplating if I should pause heavily paying down my student loans to save up for a down payment on a property to invest? My hopes are to speed up the process of paying down my debt...but I haven't found anything higher than an 8% cash on cash ROI with $460 monthly cashflow. With those numbers, I won't be speeding up my process any, I'll actually be pushing my timeline back two months. Any advice? What are the bottom-line ROI % / mo. cash flow amount that you invest in?
