How would I narrow down the criteria for absentee owners on list source to get better results?

To merge Marcel's and Bob's ideas some (and I think Bob is spot on that most association managers would feel this is their job and maybe even some encroachment on it, as working with vendors is right in their wheelhouse)....Maybe narrow your target market to (1) Self managed condo and homeowner associations.

It's an extremely narrow minded viewpoint. 

To narrow down this demographic, you will start by choosing the "Geography" of where you're looking (I'd pick the State and County of whatever market).Next, you'll search under the "Property" tab and use the "Equity%" filter.

Appears as if you have begun to narrow down the niche of real estate you wish to embark on.Bigger Pockets has various resources: ebooks, blogs, forums, podcasts, webinars, colleagues, keyword alerts, an awards system, s learn section, informative people in many fields of real estate, and more.Consider spending 30 minutes for 30 consecutive days on Bigger Pockets.

No way to get to legal code,,,too narrow,,, too short on headroom...Aim was to make "better" and it has,,,greatly.Been wanting to do this bucket list improvement for 35 years,,,finally had the brainstorm to design and DO it!!!

There is a bunch of "criteria fields" you can use to narrow your search, but agents don't always fill out everything on their listings so it might cut out something that could have showed up.

You narrowed down the niche you interested in.

We focused on a 40 block area, and in hindsight I wish we had narrowed it down even more.  

A friend of mine said "you need to put that money to work & live on the interest earned at 10% so this person that narrowed my money secured it with a note that had 40 acres of new almonds.
