What lead source is working for you? (probate, tax delinquent,..)

[Matthew Burns]

There are plenty of lead sources available, but what has been getting you the best success rate? Probate, tax delinquent, driving for dollars, absentee owner, etc.?

In my market, I've been using tax delinquent since it's freely available, but it's clearly being used by several investors/wholesalers for that reason. I prefer cold calling to get directly in contact with sellers, but I'm looking for another good lead source. What lead sources do you recommend?
