How can I better automate finding of pre-market deals?

[Lincoln Bartlett]

Hello! I am trying to find more properties that are good flip or BRRRR candidates. Everything my realtor sends me is already on Zillow and has many eyes/bids. Therefore, I'm trying to use technology to get an edge.

Aside from grass roots networking, what technology can help me find pre-market deals? For example, houses where the homeowner needs help and may consider selling to me. 

I have seen services like Likely.ai, PropertyRadar, PropStream etc.

I'm also open to coding via Python based on publicly available APIs. 

Any tips on where to focus my time is greatly appreciated!
