Cash out refinance OR line of credit?

[Alex Stariha]

Hi everyone new to bigger pockets and hoping I can find some help. I'm a young guy just starting to invest and in my mind I have a few options but don't know what the best way to go is for long term investing. I've got a 3 unit in chicago right now that's an fha loan that has 25% equity in it today. Then I have 4 single family homes in Indiana three of which I own free and clear. I want to purchase more but don't know if I should cash out refinance the 3 SFH's or get a line of credit on them.
