I only have experience with regular single-family homes as STRs.

After that I would read every single book on fixing up properties that you can find, and how to find off market properties and then start implementing those strategies.  

But it is very much applicable to single family rental and residential units simply by getting bridge financing and a post transfer cash out refi.

I was using Cozy and it was super simple and easy to navigate.  

@Cameron Gomez are you looking to house hack a small multi family property or single family and rent each room?

@Jennie Berger The RS-3 Zone allows for Single-Family residences & 2-Flats as "Permitted Uses"; however, the RS-3 Zone still requires 2,500 sq.ft. of lot area per unit (i.e. 5,000 sq.ft. for a 2-flat) unless the lot meets the exception for the characteristic of the block as previously mentioned by Nicolas; then it can be reduced to 1,500 sq.ft. per unit in order to construct a 2-flat.

Now all taxes are based on a super low rate you can’t fight. 

Possibly set up a single website and consider driving early business there from VRBO or AirBNB to get some initial views.

We both live in MI and my current plan is to invest in single- and multi-family in solid, path-of-progress neighborhoods in metro Detroit, and also get some larger SFH's in the more expensive market where we live and do rent-by-the-room/co-living.

Not for a single airbnb like you are seeking (you and everyone else) but because if you start a BNB or a guest house or a hotel, you can get 40% of your investment back in the form of a tax CREDIT that you can sell for about 90 cents on the dollar.
