Tell your listsource you're looking for Non-owner occupied homes but owners live in NJ. If you're seeking homes with equity, you can also tell them other than non-owner occupied, you want free and clear homes or less than $100k (or any amount) in mortgage.
When I ordered a similar list, I got non-owner occ who lived in the same State (NJ) where the homes are located as well as, out of state.
Hiring old man, lady, college kid...never really work out on a promise that you'll pay them when they get the info. Motivation is never there.
