Real-estate finance courses online

[Matt Laird]

I'm looking to further my education, granted you can get a ton of knowledge from reading the blogs here and their are tons of non fiction books. Have any of you found an online course or set of courses that is a must have to further your investing potential. I'm not worried about a degree to show my friends, I just want the knowledge.. I'm thinking ill need it to cover Excel, Basic Accounting, Macroeconomics, demographics & possibly investment specific market analysis. I can find these courses individually just curious of a better resource..

Thanks in advance
