How do you find buyers ( in and out of state ) to help move off market inventory?

[Brandon Auberry]

I am a new REI agent and I am just getting my book of investors started. What are some of the best practices to find new buyers in a market such as Missouri? I have found a lot of use with Facebook groups, but it is not bringing in leads at the rate I would like while trying not to spam the feed. I have networking events in the future, but am looking for something I can use online until then. Our deals move quickly and I don't want to miss out on making good deals.
