Basics of a commercial deal

[Matt Faix]

We recently found someone looking to sell a mid-sized commercial property. To-date we've only done smaller deals (duplexes/triplexes), and have self funded everything with bank financing. This is a much larger deal, and at this point we don't have the capital to do this one ourselves. We're still working on the numbers and evaluating the deal, but assuming the numbers are favorable, we're looking for what to do next and how to put it all together. 

We have friends and family that have expressed interest in investing with us, and we're fairly certain that we could get the funds through our network, but we're unsure of some of the basic mechanics for making it happen. 

IE - Do we raise money for the down payment and use a commercial lender for the rest, or do we raise the whole amount? What is a commercial lender looking for in terms of underwriting? What percentage would we, the buyer, typically need to bring to the table? Can we raise money from multiple people or does it have to be one investor?

I know these are rudimentary questions, but any help is appreciated along with any other advice for getting started in commercial properties. Thanks!
