I personally recommend searching around BP (& Facebook/Instagram/LinkedIn if you are on social media) for RE investors in some of those markets that you are very interested in as specific as you can find and sending them a direct message simply looking to connect.

@Shai Dahari BiggerPockets has an agent finder tool, I am not sure if you saw it: https://www.biggerpockets.com/...I would also ask other out of state investors who invest in Indianapolis for their recommendation. there are a bunch of Indianapolis real estate investment Facebook group that I would also check out and ask for recommendations 

When you find a buyer, there are people who have good deals on Facebook and you can easily make a JV with them. actualy you hitting two birds with one stone.

Start growing your network, look on Facebook/BiggerPockets for different events, find a mentor doing what you want to do, and get to know the local lenders/brokers.
