Primary Site for Properties

[Eric B.]

I get there are many avenues to finding properties, but general browsing...  I am finding Realtor and Zillow that people listed have gotten good at making everything show up, degrading the use of filters.  As an example, If I search Multi-Family I get every condo/apartment (individual units).  If it is what it is, I'll comb, but wondering if these are the right sites or if I am just the new guy that the rest of you laugh at for using Zillow.
