Amount of properties and Monthly passive income

[Joe Sniadowski]

Spent the last year studying these boards and podcasts and BP books before i make the leap into investing, but just out of curiosity, im wondering how many units you guys have and what you collect monthly on average with those numbers?

I live in the philadelphia suburbs and realistically in next 5-10 years would like to own about 5 properties and collect about $300/month on each or more.  Thats $1500/month not to mention equity.  Then eventually houses paid off and collect possibly $1k/month per property.  

Some of you seem to have dozens if not 100s of units and i just cant fathom how much passive income you collect monthly.  Am i missing something or are a lot of you multi-millionares?  

Just wondering if im setting my realistic bar too low
