Listsource told me that their equity range criterion is an estimate/calculation based on the date of purchase. 

I'm interested in obtaining a "100-to-100" percent equity list from them, where there is 100 percent equity in each property in the list. 

To me, by definition this should include:

1.  Properties purchased w/ mortgages that have subsequent mortgage discharges on record with the respective county, and..

2. Properties bought with cash.

My goal is to have confidence that the list I want (of properties with 100% equity) includes properties bought with cash.

So I understand how they identify properties that meet the first criteria; but what about the second one?

The only thing that makes sense to me, is that they single-out purchases where there's no coinciding mortgage on-record.

I asked Customer Support, and they say they're going to "research" this and let me know how they identify cash purchases.  

But I was just wondering if anyone on this forum might know the answer, in case I never hear back from them.

Thanks
