Though I appreciate the idea of finding online resources and studying them, I find that a curated, tried and true formula (if it works) is much more worth my time than spending time trying to find which resource works best and then spitballing the ideas until something sticks. 

There are some resources available for flippers.

The PadSplit platform should be used as a resource/tool but please engage with the people in the organization.

The Rental Property Association of Wisconsin is a resource for connections with contacts that own rental portfolios, legal presentations and resources, and contractors.

Do you have any recommendations for real estate agents, contractors, or other resources in the area?

Some tips:1.

If you really want to supplement your income, my thought would be to take out a HE loan (or some other 2nd position loan) and use that to fund a down payment on a property.

The second offer is both insulting to you and also tips their hand because if they have ~$50k in cash then they should be able to put down a higher down payment if they are serious about the property. 

Welcome to the community and be ready for a huge amount of information at your finger tips.

Can anyone suggest training videos, books, or other resources that would help educate me on the topic?
