Listsource/Propstream for First Time Homebuyer Leads?

[Noah Kanter]

I live in Burlington, VT and want to get out of the rental market and into a home. I know, bad timing. I'm tired of passively waiting around using the MLS as my only lead source and I'm wondering if/how to use Listsource/Propstream for my purposes.

I'd like my first purchase to be a duplex or SF live-in flip. I'm a paint contractor and I'd be comfortable handling everything from flooring to sheetrock plus some carpentry. 

I'd like to build a list and send out postcards, and my biggest question is which search criteria to use. With low inventory and the potential for insane bidding wars, what kind of person might be interested in selling their home, but for whatever reason doesn't want to list on the MLS? Which filters do I use on these sites to increase my likelihood of finding them?

Any advice would be greatly appreciated!
