How to acquire more than 10 SFH?

[James Wierzba]

I have been acquiring single family homes over the past 2 years. I have 4 right now. I basically just save money from my job and the cash flow until I have enough to purchase another with a cushion and rinse and repeat.

Question: After I get to 10 properties/loans, and I can no longer qualify for the standard Fannie Mae / Freddie Mac -- how can I finance additional single family homes? Is it possible to roll all of my individual mortgages into a single mortgage?  

I have a high paying job and very good credit score. Not sure if this helps at all, since it seems financiers don't really care about your 9 to 5, they care about the investment property itself.
