Finding Apartment Buildings

[Glenn Clapp]

Greetings all!

I did a few searches on BP, but didn't see this specific topic, so I thought I'd give it a try.

In this world of big data and the "interwebs" I am curious of anyone knows of a search that can list all-- say 20+ unit apartment buildings that exist in a city, or region.  I've seen lots of different ways to search generically, but not having much luck in finding addresses and owners of specific property types and sizes. 

No, loopnet doesn't count. 

Admittedly, I'm pretty new at searching for general property details in any shape or form, so it would not surprise me if a search like this is super obvious and I can slap myself in the head.  At the same time it wouldn't surprise me if such a search was entirely manual or doesn't exist (yet).
