Pricing Multi Family Properties

Hey everyone.  I'm new real estate agent that is looking to specialize in working with investors.  My goal is to work mostly with multi-family properties.  From what I understand, these properties are priced differently than the average single family home.  I read an article and I am curious to know if anyone else uses this this method, or do you price them a different way?  

Here is the excerpt from the article:

For instance, if the property had an NOI of $150,000 and the cap rate was 6, the property value would be $2,500,000 (150,000/.06). If the NOI increased to $180,000, the value would increase to $3,000,000. A $30,000 increase in NOI generated a $500,000 increase in value.
