Should I expand my search from 2-4 units to single family?

[Matt Ashbrook]

I've been looking for my first investment property for 4-5 months now.  I've put in a few offers, but been unsuccessful so far.  I have been looking for 2-4 unit properties for the same reason everyone is, but mainly for me is the security of multiple rent checks coming in.  I just got outbid on a triplex, and I'm getting discouraged.  I'm considering looking for single family just to get started, as I know that's an important part of getting started (you know, actually getting started).  All of that said, I'm starting to feel like building a portfolio of 3-4 single family homes is similar to having a 2-4 unit property.  What are everyone's thoughts on this?

I'm in St. Petersburg, FL, looking in the St. Pete, Tampa, Clearwater, FL area; looking to BRRRR.
