Portfolio management question

[Dave Hart]

I have 4 rentals. All cash flow positive. I’m running out of capital to buy more. One option is I can cash out refi one property that has $400k in equity. 

If I take out $200k, that property will have a negative cash flow of $500, but the overall portfolio will still cash flow positive and I'll have capital for another purchase. My attempt will be to BRRRR and recycle as much capital as possible.

Any thoughts if an individual property can negative cash flow to provide capital as long as the portfolio is still positive? 

Thanks all
