Do You Buy Real Estate Lists to Market to? If so, what kind and who from?

[Joshua Dorkin]

Hey guys - 

I wanted to get a consensus about those of you who buy lists for marketing purposes. 

If you buy real estate lists (e.g. probate, absentee, properties with equity, etc.), can you chime in with:

1 - What kind of lists do you buy?

2 - How often are you buying these lists? 

3 - Who do you buy your lists from?

Thanks everyone!
