If you’re comfortable with a bigger investment, a duplex is good for the benefit of additional cash flow and you could house-hack.

I only have 1 property under my belt and am currently house hacking my SFH. 

I'm curious of the current market demand for student housing and appeal to rental investors.

Flipped a house before?

Non-passive to achieve this level of return.Add the addition of the ADU makes the main unit rent controlled if over 15 years old.the work to add an ADU likely exceeds the effort of a brrrr that can achieve infinite return  Experienced investors are adding multiple ADUs by leveraging items like bonus density, committing units to affordable housing, etc.  

@Adam Luepke - Great first house hack! 

When entering the apartment, it just feels like a house full of squatters. 

It’s raw land and no house. 

Are you looking to do more rehab projects like this (either house hack or not)?

In 1-2 years you could save enough to purchase a home to house hack.
