Finding Properties to Wholesale

[Austin Ralls]

I am a Fix and flip investor in Oklahoma, but I am wanting to get into the wholesale side of everything and I am curious how do I find the properties to send my letters too. I have been on the side of contacting the wholeseller and receiving the property they are listing for someone else, but I am wanting to know what strategies I can take to find properties and owners that are looking to get rid of their properties. I know I can do the street signs and put my number all over the place, but was wanting to know if there were any other strategies that could help me find properties that I'm not thinking of. 

Thanks in advance.
