What’s a better leveraging options for all experienced investors

[Dorian Guin]

I'm a relatively new investor, debating which strategy would work in leveraging some properties I own free and clear. But with recent changes in the markets I'd love to move in moderation. Options I'm considering is, would I be better off taking out HELOC options on the properties. Or taking out a mortgage on current properties that is already tenant occupied? Thanks in advance for all insight available.
