Listsource: Equity Unknown?

[Stephen Polizzi]

I'm putting together a listsource list for SFR in my target area, and I'm seeing 255 results for my criteria unless I add in Equity Unknown to my equity filter (30%+), in which case it goes to a much more desirable 1052 records.

Am I wasting time and money including the Equity Unknown or is it worth the additional investment to cast a bigger net?

I've searched extensively on this, so if you know of a good post where this is addressed, please link, I'm not coming up with anything. Thanks!
