What is the market for selling list of bird dog leads?

[Clayton Smith]

In between my day job and keeping busy while bored, I stumble accross houses that would be great investment candidates. Essentially, I am finding "driving for dollars" leads. I'm not yet committing full time to wholesaling for myself, so, I'd like to see if there is a market out there to sell the leads I find...

Example would be I am in an area of town for work and I take a stroll through a neighborhood and find 5 houses. I can get the addresses, take a photo, and get the mailing address from the tax records, etc. Can I sell this package of 5 addresses? 

Then what would be a good price per lead? Then I can guage if my time is worth it to put together larger lists, more detailed, etc...

Hope this makes sense. And I know this would be a very localized project, not for everyone.

I've seen plenty of ads on CL, and people at REI groups looking for bird dogs. Never seen one that paid by the lead or hour. They all paid on closing.
