Equity % for Direct Mail

[Taylor Ernster]

I use ListSource to create my lists and unfortunately it appears in South Dakota, or at least my part, it does not pull equity information. Whenever I add this criteria, the results drop to 0. Has anyone else experienced this and is there any better work around besides using length of ownership criteria? 

Is it more of an information missing problem or what are some other websites to purchases lists from? This is a major criteria to find qualified leads and if I cannot access this, I'll be mailing many individuals with little or no equity .

Any advice would be appreciated!
