Getting the List of motivated sellers

[Jonathan Mariscal]

I wanted to know if y'all would have any tips on how to get leads and motivated sellers to get deals for wholesaling. I am having trouble on where to start at to find sellers. I wanted to buy leads from those websites but i heard i could get those list from the tax assessors office and by doing other things like making signs and mailing post cards. My biggest issue is just getting the list with possible motivated sellers so i can start mailing postcards and taking action. 

Also if I drive and look for rundown, abandoned, old homes who might be owned by motivated sellers, how would i go about and finding the owners of those homes to get in contact with them.
