Also, controlling more property through leverage maximizes your after/tax income, due to all the depreciation, so you really need to do all your calc's after tax.As a risk management step, it makes sense to ensure that each property has a minimum $ amount of cash flow that you're comfortable with (using 50% expense guideline), and has a Gross Rents:P&I ratio that is healthy (at least 3.50, possibly 4.00 if you're a bit more conservative).

Regularly review and update your strategies to adapt to changing market conditions and maintain a healthy cash flow position.

I would most definitely do a cash out refinance provided that your cash flow is still healthy enough including maintenance and CapEx reserves.
