Finding Commercial Deals

[Philip Tretola]

Good morning - I am relatively new real estate investor who has purchased two multi-family (2/units each) properties in the past several months.  I am looking to increase the number of units per structure and therefore am looking for commercial real estate (targeting small apartment buildings w/ 5 - 10/units).  However, finding these types of listings/offerings/deals is more elusive than typical residential real estate.  

I was wondering if anyone has guidance and/or advice please on how they got started and any other wisdom?

Thanks in advance for your valuable time!
