List Source pre foreclosure - very small numbers

[Declan Shanaghy]

I created a pre foreclosures list in listsource for my local area (SF Bay east area) I made it very specific - sfr,duplex,tri,quads, auction date within 2 months. 

It filters down from 1.5 million to 57 addresses. Now, even with the given that these 57 people should be highly motivated I'm wondering if it's going to pay off. This is my first time endeavor and I'm planning on setting up a website with squeeze page and call tracker to help out since I'm also working full time. So there are other expenses involved.

What are your thoughts on on the potential?
