I'm choosing to pursue a Facebook marketing campaign instead of a direct mail marketing campaign.  However, i'm trying to figure out the optimal list to build for this purpose.  I'm using ListSource and I know what I want to choose geographically, but the other aspects of the list criteria are a little confusing; mortgage types, demographics, property types etc.

What sort of things should I be considering in building a list to target possible sellers?  What would be the best way to build this list? 

As always, all assistance is greatly appreciated.

@Craig Noyes you basically want to limit your ListSource list down to the qualities and characteristics that will make a deal happen. For example, if you know your buyers want houses and not multi-family, narrow your list down to that. If you know you have to buy houses at 50% of ARV then you should probably make sure they have enough equity in their homes to be able to sell them to you at the right price. Hope it helps!
