New to REI - SFH vs.MFH

Hi All! I'm Eric and I'm looking to start my journey in REI. I've done a lot of research and plan to untilize a HELOC on my own home for a down payment and finance the rest. We have some reserves as well in case things come up but that is our plan to start. I'm torn as I've done a ton of research and I'm wondering what the best first rental purchase would be (single family vs. multifamily/duplex )? Was initially thinking MF but now am considering SF. This wouldn't be a house hack with me living there, it would only be for renting it out. Just Looking to get your opinions to gauge which direction I should head. Thanks in advance!
