Best Process for quickly screening out props in MLS?

[Neil Polehn]

Hello All,
How do you quickly separate the wheat from the chaff so you can do a deep drive analysis on on the few?  I am looking at 40 mls listings of MFR and I need a quick way to eliminate the losers, some of which do have rents listed so I will have to look them up.  How you quickly eliminate the losers so you can focus on the deals when looking at the MLS or alike?  Thanks!
Neil
