Is it possible to find good deals on MLS?

[Alexander Schwartz]

I have a simple quick question. I'm a realtor in St. Louis and aspiring investor. I have access to MLS and am mostly looking for commercial property. Is it unheard of to find good deal on public MLS? I found a 5+ unit apartment building that seems to net 35k~ a year, fully rented, selling with some other property included near by if buyer is interested in that as well, seems pretty solid and i know the area and it's a good area and what not.

Is it just too easy/good to be true on public MLS or worth looking at?
