Understanding How to Calculate a Commercial Mortgage

[Mike Louis]

I'm new to investing and made some calls to lenders to try to understanding more about commercial lending so I can properly calculate and estimate monthly payments. I spoke to a gentleman that told me for multi family properties, I would get: 30 Year Amortization 5+5 or 7+5 maybe 10 Term 3.5% and Up Rate This confused me because I'm used to calculating with a term and a rate. Can someone explain to me how I would calculate the above and what they mean? I appreciate your time!
