I'm questioning Propstream's accuracy, help!

[John Mucilli]

Not exactly a wholesale question, but figured the wholesale forum would have followers that are savvy with Propstream.

I've been getting familiar with the software by doing research on local properties. I am finding that there are TONS of errors, and its making me second guess sending out a marketing campaign to a list. I have a particular list set to exclude any sales after 01/01/2017, and after cross referencing some properties, I've come across plenty that have been sold recently. Also, I have "off-market" selected and there are plenty of properties that have been listed this year and are now pending or sold - but they show as a failed listing. 

Is there anything I can do to make my searches more accurate, or do you just market to the list anyway and take the losses on properties like those?
