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

If the Minnesota market has duplexes or 2-4 multi-family units, this could be a great way to get started.If you already own a home, then I would say to do some research on the top places around the country to invest in and build a team and a network of experts in that area. 

Maybe selling into something with better numbers or lower headaches is the right decision for you, however I want to encourage you to speak with a few different experts along the way so that you can account for all of the important variables. 

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.
