Current PM looking for advice on learning analytical / financial side of RE Development

Hi all and thanks for taking the time to help out.

I'm currently a PM for a major CM firm with ambitions of one day being able to do multi-family development for my own firm. While I have significant experience in construction and its methodology (5 yrs currently), I lack experience from an analytical/financial standpoint of development. I'd like to learn some modeling and financing aspects of the business. I was thinking of getting a CCIM designation as it seems to be a good primer for these skills and it would give me a solid base to work off of for the MSRE or MSRED I plan on doing in the near future.

While my BA is not finance or RE based, I do have a minor in Econ and I have ran through a number of books on development and the financing behind the decision process.

Would a CCIM be worth my time to learn these skills or is there another avenue I should pursue? I'd really like to become more proficient in Excel and financial modeling as well.

Thanks for your input.
