Package Deal Analysis: Separate or Combined?

[Dan Nieves]

I am trying to figure out how to analyze a packaged deal.  The proposed example is 4 duplexes and 1 quad.  With regards to analyzing the deal in the BP calculators, would it be better to separate each property and combine the results with averaging the returns? or combine all parts of each property and treat it as one giant deal?  I am a newbie in all sense but if I can focus on trying to grasp this concept, I may have a chance at a real possibility like this sooner rather than later.

Thank you all in advance who reply.

Much respect,
