The main factor is will rents cover the debt liability and can you sustain 3-4 months of no income to cover the debt? 

Currently, I'm analyzing different markets to see which one will best match my strategy.

I already rent and live in apartment units - which wouldn't be that different living in one of the units in a 4plex.

Is it a position they could keep if they were in a different state than their employer?

So my perspective on how to get started may be different than others who are professional wholesalers (100% of what they do is wholesale).

Kind of a different ballgame but also kind of just like it’s always been.  

They could offer different products for single family vs multifamily so it's a good idea to get with a lender to see what they can do that may not be your typical mortgage type.

Duplex have different zoning that may permit additional units.

Also, it lends itself to unconscious bias because we are more likely to view negatively people who are different than us.

The energy in person is different for me, and I've made some of my best connections and friends at Chicago meetups.Here is a list of the Chicago event from BP: https://www.biggerpockets.com/forums/521-real-estate-events-...I also have a list of ALL THE CHICAGO MEETUPS that I am happy to share with you.
