I would be careful about doing something in an effort to "make positive cash flow".Section 8 has its pros but there are an equal number of drawbacks.

Not all agents are created equal when it comes to investments.

I know a lot like to dismiss timing, but it's equally important on the way in & out.

There are a handful of gulf front complexes that still cash flow positively but you need to be very careful as to which complex you choose as not all complexes and especially HOA's are created or managed equally. 

Contrary to popular belief, this is actually an advanced strategy for people with lots of experience and resources, it's a really tough place to start.

If you buy in such a city, you are almost guaranteed to have limited appreciation and rent growth.If a city has significant and sustained population growth, then the current housing supply will be insufficient and prices will rise until the demand (the number of people willing and able to buy) roughly equals supply.Rental rates are closely tied to property prices.

Equity and cash flow are equally important when deciding whether to pull money out.If you can put the equity to work by adding another property while still having a nice cushion on your cash flow, then I would say definitely yes.
