Struggling in finding deals

[Xai Xiong]

I have been searching for properties on the MLS and talking to realtors and getting our offers rejected more than several times on several properties, I'm guessing due to competition of other people being in better position than us. So I've recently have been looking into starting my own yellow letter campaign, but can't seem to purchase any lists on listsource.com. Is this site out of date/order now? Is there any other sites similar to this? Am I doing something wrong? I'm really kind of stuck and any tips or advice will help!?
