My first home purchase was a duplex, and I have enjoyed it so far, although in Massachusetts it's very difficulty to cover full Mortgage cost in a duplex.

Charge something extra to use it? 

So from start to finish with one extra R in my BRRRRR it was 18 months (first loan after 6 months and another loan after 18 months).

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

Win, win - I got amazing interior design help & she got extra money to feed her kids.

In gentrifying areas - Wash Park  or the Highlands in Denver, West Port in KC, the old North East  in St Pete, (name any other of 1000 old neighborhoods that are suddenly hipster friendly)  this can be a gold mine.So, if you've got an extra lot you need to think about. 

Even then, doubtful they will do it due to the extra risk and hassle of dealing with a superior lien in the event of foreclosure.3) Hard money can sometimes be secured by other assets. 

@Chace Fraser I’m looking to build a small portfolio that would bring in extra money each month and eventually help me retire early.

Stay an extra day and come to @Andrew R.

Best way to go is just to fork over the extra 10% per month and get a property manager.
