How did you build a pipeline for deals coming your way?

Hi everyone!

My partner over the years has been able to build a really solid network of hard money lenders, and we have access to a few mill now. He also built a really good team of workers to do flips (he's a general contractor himself). We now need to work on building a steady flowing pipeline of deals. I'm going to help with this. Wondering what others have done and what types of businesses they networked with to access good deals pretty regularly? Other than looking at the MLS or networking with wholesalers and realtors? Anything else?

thanks!
