The Airbnb calculator estimated higher returns than in most places I've looked, as did local property managers.

Find a few GC's local to the market you're interested in. 

Talk to some local property managers on their screening guidelines and even inquire how long they are seeing their properties sit on market to really sharpen your decision!

Bank Five Nine just launched a new DSCR product last week, but there are several local banks in Milwaukee that are great to work with.Have you been to Milwaukee and have you seen this property in person?

I would look into local and state apartment associations.

Trick that I am learning:  work on overcoming your fears, pull leads, get on the phone, talk to sellers, local brokers, other investors, other RE partners, etc. 

I'd start locally doing BRRRs, use your experience.

This team should include professionals like agents, lenders, contractors, and property managers.Lastly, connect with other investors and attend local REI networking groups and meetups.

I'm a total newb, but I believe MLS-access in MO is controlled by your local Board and NAR.  

A few local investors I talk to say it is normal (for them), but I am looking for other input as well.
