30yr vs 15yr fixed conventional mortgages

[Bryan Blancke]

I plan to build a portfolio in cities near Royal Oak Michigan for cash flow and equity with a buy and hold strategy focused on small multifamily units. I work as an engineer with a stable salary and I am planning to finance my first four deals with conventional bank loans. My first thought is to go with 30 year fixed mortgages, but would it be unwise to not consider a 15 year fixed mortgage? I wonder if I could even cash flow with a 15 year mortgage in this area and if it would work with my overall business strategy. I would be trading higher cash flow for equity, which I don't think would be worth it starting out. I expect the higher cash flow to more important than building more equity to leverage for future deals. I don't need the cash flow for my living expenses and plan to use it for reinvesting in my properties or into new properties.
