Who Calls on my Bandit Signs

I have used a spreadsheet to track the type of caller who sees my Bandit Signs and calls in. Here are the types of people who call me, with the number assigned as to how many are in that category:

1) people who want to sell their place which likely fits my criteria, but are not motivated to sell really low. (47)
2) real estate agents (14)
3) people who are motivated & the properties fit me (5)
4) people who want to sell a mobile home, etc. (no land) - (4)
5) crank calls (1)
6) zoning officer calls (9)
7) people selling properties that are too high for my criteria (14)
people who want to rent - (7)
---------------------------------

As you can see, I am getting a LOW # of callers who have starter homes that they NEED to sell. I am thinking that going directly to the pre-foreclosures property owners is the way to go. That will likely entail Door Knocking on people who are under quite a bit of stress and edgy. Yikes!!!
