Any pinsiders invest in real estate rentals?

I paid my way through college and grad school on single family houses. I called it the slow flip where I would buy a crappy house and fix it up for 3 years and then rent for 2 and sell to avoid capital gains on primary residence (have to live in it for 3 out of last 5 years of ownership). I then sold those houses over the past few years while putting my wife through professional school.

She is nearing completion and hopefully returning to gainful employment in a few months, which means I am starting to research future investments. I would to stay in real estate as I like the material asset and also the possibility to draw an active income off the investments.

I am only familiar with managing single family and am contemplating either smaller business real estate or maybe a 4-8 unit building for my next jump.

If anyone has any insight or real life experience and is willing to talk, please let me know.

I have a year or so before being ready to jump but am starting to research options more at this stage.

Yeah, I know all the basics. Just was hoping to talk to someone that has been down th path of single family to multiple unit rentals or light business rentals and maybe hear about what they have learned along the way.
Where is the 1000 unit going? That is crazy big!!!

I wondered if that was ever going to pick up steam again. That will likely have minimal impact on my current home either way, but may impact (more steer) where I buy rental property. Similar to stocks I always suggest buying what you know in real eastate so I will likely focus closer to my current home. I am also focused around the rebuilding on 51 and all interchanges which will impact how the city grows for the next 10 years on the eastside.
