Newbie investor need advice

[Mark Weinmann]

Just purchased a four unit with the goal to purchase more properties more so commercial. So I would like to know what's the best strategy as a newbie to increase my portfolio. My strategy as of now would be to do a cash out refinance of my current four plex then buy another four plex as owner occupied then in a year repeat. But I want to decrease time spent doing this if I can jump into commercial 5+ units. Any suggestions?
