Real Estate Financing

[Wendell Clark]

I am looking for a free online Real Estate Course that teaches financing.  Does anyone have any suggestions?  Is there a book that someone would recommend?  I read some of the online discussions about financing, cash flow, and the best way to purchase a property.  It seems to me that there are different views as to which is the best way to go.  I am looking to educate myself, so I can decide the best way to proceed.  Thank you in advance for your recommendations.
