I have yet to come across a more comprehensive metric.  

Wow, thank you all for such comprehensive responses. 

General overview is each person would contribute roughly the same amount for a downpayment. 

Here is a short list, probably not completely comprehensive:-Sales, relationship building and negotiation skills-Ability to read and understand most contracts and financial documents-At least a working understanding of common commercial real estate terms and concepts-An understanding of how commercial debt can be structured, what the different loan types and who the different lenders are-Money to fund deals (either in the bank or relationships with passive investors ready to write checks)-Multifamily ownership Experience to sign on the loan and to make raising the money easier (probable possible without, but much better with)-Net worth and Liquidity requirements to qualify for the loan.

I appreciate your high-level overview with the #'s @Justin Silverio Thank you!!

Not to mention the comprehensive, detailed content.

I am a bit lost....Perhaps it is because my reading comprehension and attention span both need work :D

I found the Millionaire Real Estate Investor by Gary Keller to be a great overview that would lead you to more detailed learning.

So hire a competent commercial realtor to save time and give you a comprehensive research on new development, growth, demographics, or comparable lease/sales rates in the area.2.Get pre-approved – when you get pre-approved for a loan, it will save you more time because you know exactly what you’re looking for.

But gives a great overview of development in the city.Cheers,Ben
