- Buy a cash-flowing, turnkey duplex in a C+ location in a growing city like C0lumbu5, 0H.

If they are in a mobile home park, there will be restrictions as to what you can do (same as if you had a condo).

Single boiler serving a duplex- landlord paid water / natural gas because there's no way to split it accurately. 

Not earning a high income I have slowly invested in duplexes over the years.

I'm on my second house hack (condo) and then my wife and I house hacked our ADU/Main House.

Noise and parking are always an issue with duplexes and multi-unit housing. 

Same with condos in my opinion.

1 Bed 1 ba condos can be difficult at times, making the design as unique as possible such as adding accent walls or expensive finishes throughout the home that matches your towns aesthetic/niche are valuable additions to smaller homes where you can't usually add a pool table or other amenities you would find normally in a house. 

One of the main reasons is that almost no one will actually have a property manager on a duplex.

I have a duplex near a Mini Mart gas station and people are constantly throwing their trash on my property.
