Marketing for owner carry notes

[Derek W.]

I just bought a note from a lady who sold her house and carried back the financing. The guy she sold it to never made a payment. She was too broke and didn't know how to get him to pay. I was able to discount the note for a great price and get her some cash to fix her car so she doesn't have to walk to the store anymore. I found doing the negotiation and workout to get the note performing to be very enjoyable and fresh for a burnt out rehabber. Lol

I want to do lots more of these.

Question: How would I find the data to market to more owner carry note holders?
