How does new western find their off market properties?

How does new western find their off market properties?

I’ve join a brokerage not too long ago and learned how to cold call. The problem for me is that it is pure cold calling. The lead gen just has their number, no info about the properties nor their names. 

So I wanted to ask how do new western agents and other people find off market residential/commercial. I’ve been dabbling into d4d and direct mails, but I’d like some advice if you guys use other methods or even softwares like propstream 

Thank you
