Using Craigslist to find motivated sellers

[Heath Thomas Jr]

Has anyone in the DC area found craigslist an effective source of finding motivated sellers? I did it for 3x a day for 2 months, a few months ago. I didn't really get many results, a couple of people visited to my website, but it led to nothing. 

I see many other investors do it in the area. I'd like to give it another try but wondering if it's worth it ( either the time to post, or the money to hire a VA longterm to do it)
