What is a good way to find motivated sellers?

[Christopher Verissimo]

I got a new job as a Acquisition Manager for FDR Homes. And my job is to find distressed properties that we can buy, fix and flip. I'm walking around every day with a note pad taken down the addresses I think would be a good fit. Then calling them the next day from the yellow pages but I get a lot of no pick ups. Or out of service phone. Any one have any advice for this beginner?
