Cash out refinance or sell

[Jordan Blanton]

Looking for opinions on what my next move should be. Own 2 investment properties plus my primary residence. Here's breakdown:

1st home: paid off (paid 56k) now worth approximately 140k, cash flowing $650.  

2nd home: purchased last year and is cash flowing $715, approx 50k in equity.  

Primary residence has appreciated well and now has approx. 120k in equity. 

Curious if I should get a cash out refinance on my paid off property to acquire two more homes, even if they're not cash flowing all that well. Or should I sell the property outright and use a 1031 to acquire more expensive homes.  I'm 30 years old, so ultimate goal is to build control and wealth over as much real estate as I can. Any thoughts and opinions would be greatly appreciated!
