Investment Performance Analysis (financed -> loan paydowns)

[Jerry Poon]

I have been financing all my properties, and analysis via Cash on Cash has been serving me quite well. With the market being the way it is right now, I've moved onto cash buys and paying down my loans for now.

Since the properties will all get an artificial bump in performance once the loan is extinguished, Cash on Cash doesn't seem the most appropriate for my situation.

What performance analysis metrics would you suggest to capture loan paydowns appropriately?
