To scale successfully you have to get past the point where your newly increased expenditures exceed your increased revenue; past the point where your ROI allows you to “break even” on your investment, and past the point where the ROI is worth the increased risk, the increased aggravation, time, and “lifestyle” change, and past the point where you can step back from “operations” and concentrate on management.  

But after an exchange - sign the purchase documents with one pen and pick up another pen to sign the refi docs :)Another strategy you could consider is reinvesting into multiple properties, where you purchase the first property cash (ensures some security and concentrates the equity) and the second property with a mortgage.

@Randall King If you find the property isn't performing well, a 1031 exchange would defer the tax and concentrate that equity into something that has a greater cash flow potential, like what @Corby Goade said.

Your equity is concentrated and not costing you anything.2.

This could allow you to concentrate your equity in one purchase by doing it in cash.
