Just starting out. My situation. Help!

[Account Closed]

I am a new investor in Portland, OR.  I want to make flipping houses my primary source of income for my family. I am working on getting financing going. I want to be doing 2-3 houses at a time. I personally have 500k of my own cash ready to use anytime. I will need access to more money if I want to do multiple properties. I have excellent credit. What type of financing would be best for my situation to get at least get two or three houses going in the 250-300k range. 

-Traditional mortgages?

-Line of Credit?

Other?

Any information would be much appreciated. 

Thanks,

Neil
