How much do you spend on acquiring lists for motivated sellers

[Daniel Pitta]

I created an account on ListSource and built a list for absentee owners within my area. It's ~$250 to purchase the list. I still need to compile a list for probate, divorce and pre-foreclosure. I'm curious how much money people are spending on just compiling a list of leads. I hear a lot about how much money is required for a direct mail campaign but never hear any wholesalers or flippers mention what they spend on lead generation. I know that there are other ways to find leads (court records, etc.) but I'm trying to go with something as quick and efficient as possible since I have a full-time job. Thanks in advance
