I now exclusively invest internationally so I was never interesting uninteresting neighborhood stories.

Slowly build out a repeatable process...if you continue to change things (as in different types of properties, different levels of renovation, different finish material, different neighborhoods, etc.) you create more variables and make it harder to solve to the problem.I am a math guy and less unknowns/variables you have the easier the problem will be to solve. 

But, each has their own differences.That being said, in the neighborhoods I invest in, duplexes and quads have appreciated slower than single family properties.  

- You can find this out by going to Zillow, selecting your Zip code or Neighborhood, and looking at current rental listings.

@Kwok Wong With limited exceptions its customarily the lower tier neighborhoods that present both BRRRR and cash flow.

Quote from @Andrea Ward: I recently purchased a small tract of undeveloped, heavily wooded land in North Mississippi in a neighborhood.

If you are not in a good neighborhood, you will not be attracting great tenants and sharing a duplex with someone can be a highly stressful and unpleasant experience, especially if the structure is not truly conducive to being a duplex.

Like Adam mentioned, it's not a good neighborhood.

In February of 2022 we purchased a newly renovated 3 unit building in the South Austin neighborhood of Chicago.

You can organize your entries by unit, and it's all free to use.
