Should we always seek seller financing first?

[Robert Huizar]

When the end goal is to have a portfolio that provides positive cash flow beyond your expenses and meet your lifestyle, I could imagine a portfolio containing a few dozen properties and more.  Given that an individual person can only hold so many mortgages, would it be an appropriate strategy to always seek seller financing first?  I have zero mortgages in my name, so when the opportunity for seller financing shows up, should I jump on it to keep my mortgage total as low as possible?
