Cash out refinance vs. HELOC

[Walter May]

Im a new investor in the Tulsa/ Broken Arrow area. I plan to buy my second investment property soon with the equity I built in my first. I owe $60k and it will appraise around 115k. I was thinking on a heloc instead of a cash out refinance so I'm not paying interest in the money while I'm waiting on the next deal and just paying the heloc back when I refinance.......thoughts? Thanks in advance!
