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.
