Lenders for Line of Credit? (secured against investment property)

[Tyler Bobo]

Instead of a typical BRRRR deal where I'd refinance and get my money out, I'd like to get a HELOC style loan but on a 4 plex I'm considering buying, not owner occupied. I'll check my local banks and credit unions as well but just putting it out there, does anyone have a lender who would lend nationally (I'm in Alaska) that might be a good fit?
     My HELOC on my personal house has been a great tool, and even as a second position, the interest is super cheap compared to my private money alternatives. (variable, currently 3.6% or so)    Any suggestions or should I just shop local?
