Also, I found condos with less than 8 units easier to join the board of the HOA and usually isn’t professionally managed.

I've used them for non-conforming condos that were still pre-rehbab and they are pretty flexible with what they can lend on.

You might even find a couple of duplexes as $80 might be enough for downpayment. 

What is the best way I should go about finding a duplex, triplex, or 4-plex?

Some work I would need done would be some tile replacement in a bathroom shower, a leaky sink faucet replaced, and kitchen fan replaced / fixed, and possibly (I am undecided here, depends on how much the previously-listed runs for cost) some framing done - My property was originally built as a single-family home and split into a duplex, but shutting off / sealing off a door, which is still a door.

Am in escrow on a duplex set to close in 2 weeks and went into contract on 2 SFR this afternoon.

This duplex was a whopping $475,000.

If you need any connections to contractors, insurance agents, title companies, appraisers, deals (off-market single families, duplexes, fully renovated turnkey properties, multifamily properties, buy and hold deals etc I have several deals that come across my desk each day), recourse and/or non-recourse lenders, my opinion on potential properties you are analyzing to buy etc I am more than happy to help you. 

Taking on $50K in credit card debt to go through a guru course isn't the same thing as a 30 year fixed rate mortgage of $100K on an income producing (hopefully, anyway) duplex. 

Most have condo fees (I think) so that turns me off a little.
